This error event is captured by the EXCRCERI bit and is forwarded to the Performance Monitor. 4. Severely Frame Alignment Bit Error: When 2 or more frame alignment bit errors are detected in a 1-ESF-frame fixed window, the severely frame alignment bit error occurs. This error event is captured by the SFEI bit. When the Frame Alignment Bit Error number exceeds the ratio set in the M2O[1:0] bits, it is out of synchronization. Then if the REFEN bit is `1', the Frame Processor will start to search for synchronization again. Additionally, the Excessive CRC-6 Error also leads to out of ESF synchronization. In this condition, both the REFEN bit being `1' and the REFCRCE bit being `1' will allow the Frame Processor to search for synchronization again. If the REFEN bit is `0', no error can lead to reframe Functional Description 3.8.1.2.4 Switch Line Carrier - 96 (SLC-96) Format (T1 only) In SLC-96 format, only one kind of error is detected: 1.

Generally, it is performed by detecting a successive FAS/NFAS/ FAS sequence. If STEP 2 is not met, a new searching will start after the following frame is skipped. If STEP 3 is not met, a new searching will start immediately in the next frame. Once the Basic Frame alignment pattern is detected in the received PCM data stream, the Basic Frame synchronization is found and the OOFV bit will be set to `0' for indication. STEP1: Search for 7-bit Frame Alignment Sequence (FAS) (X0011011) th in the N frame No (skip one frame, N=N+3) No (N=N+1) Yes STEP 2: Find logic 1 in the 2nd bit of TS0 of the (N+1)th frame to ensure that this is a non-frame alignment sequence (NFAS) Yes STEP 3: Search for the correct 7-bit FAS (X0011011) th in the TS0 in the (N+2) frame No (N=N+3) Yes Basic Frame Synchronization Found Figure 12. Basic Frame Searching Process Functional Description 43 August 20, 2009 IDT82P2282 DUAL T1/E1/J1 LONG HAUL / SHORT HAUL TRANSCEIVER The first bit of TS0 of each frame is called the International (Si) bit. The Si bit in each even frame is the CRC bit. Thus, there are C1, C2, C3, C4 in each SMF. The C1 is the most significant bit, while the C4 is the least significant bit. The Si bit in the first six odd frames is the CRC Multi-Frame alignment pattern. Its pattern is `001011'. The Si bit in Frame 13 and Frame 15 are E1 and E2 bits. The value of the E bits can indicate the Far End Block Errors (FEBE). 3.8.2.1.2 CRC Multi-Frame The CRC Multi-Frame is provided to enhance the ability of verifying the data stream. The structure of TS0 of the CRC Multi-Frame is illustrated in Table 18. A CRC Multi-Frame consists of 16 continuous Basic Frames (No. 0 - 15) which are numbered from a Basic Frame with FAS. Each CRC Multi-Frame can be divided into two Sub Multi-Frames (SMF I & SMF II).

After the Basic Frame has been synchronized, the Frame Processor initiates an 8 and a 400 ms timer to check the CRC Multi-Frame alignment signal if the CRCEN bit is `1'. The CRC Multi-Frame synchronization is declared with a `0' in the OOCMFV bit only if at least two CRC Multi-Frame alignment patterns are found within 8 ms, with the interval time of each pattern being a multiple of 2 ms. Then if the received CRC Multi-Frame alignment signal does not meet its pattern, it will be indicated by the CMFERI bit. If the 2 CRC Multi-Frame alignment patterns can not be found within 8ms with the interval time being a multiple of 2 ms, an offline search for the Basic Frame alignment pattern will start which is indicated in the OOOFV bit. The process is the same as shown in Figure 12. This offline operation searches in parallel with the pre-found Basic Frame synchronization searching process. After the new Basic Frame synchronization is found by this offline search, the 8 ms timer is restarted to check whether the two CRC Multi-Frame alignment patterns are found within 8 ms, with the interval time of each pattern being a multiple of 2 ms again. If the condition can not be met, the procedure will go on until the 400 ms timer ends. If the condition still can not be met at that time and the Basic Frame is still synchronized, the device declares by the C2NCIWV bit to run under the CRC to non-CRC interworking process. In Functional Description 44 August 20, 2009 IDT82P2282 DUAL T1/E1/J1 LONG HAUL / SHORT HAUL TRANSCEIVER 3.8.2.2 Error Event And Out Of Synchronization Detection After the frame is in synchronization, the Frame Processor keeps on monitoring the received data stream to detect errors and judge if it is out of synchronization. The following ten kinds of errors are detected: 1. FAS/NFAS Bit/Pattern Error: The criteria of this error are determined by the WORDERR bit and the CNTNFAS bit (refer to Table 19). This error event is captured by the FERI bit and is forwarded to the Performance Monitor. 3.8.2.1.3 CAS Signaling Multi-Frame After the Basic Frame has been synchronized, the Frame Processor starts to search for CAS Signaling Multi-Frame alignment signal if the CASEN bit is `1'. The Signaling Multi-Frame alignment pattern is located in the high nibble (Bit 1 ~ Bit 4) of TS16. Its pattern is `0000'. When the pattern is found in TS16 and the high nibble of the previous TS16 are not all zeros, the Signaling Multi-Frame synchronization is acquired and it is indicated with a `0' in the OOSMFV bit. The frame containing the Signaling MultiFrame alignment pattern is Frame 0 of Signaling Multi-Frame. The TS16 structure of the Signaling Multi-Frame is shown in Figure 13. The entire content in TS16 of Frame 0 of Signaling Multi-Frame is `0000XYXX'. `Y' is for remote Signaling Multi-Frame alarm indication and `X's are extra bits. The codeword `ABCD' are the signaling bits for different timeslots.

TS16 Structure Of CAS Signaling MultiFrame Functional Description 0 0 1 1 1 Error Generation Each bit error in FAS is counted as an error event. A FAS pattern error is counted as an error event. Each bit error in FAS or NFAS error is counted as an error event. A FAS pattern error or NFAS error is counted as an error event. 2. CRC Multi-Frame Alignment Pattern Error: The received CRC Multi-Frame alignment signals are compared with the expected ones (`001011'). When one or more bits do not match, a single CRC MultiFrame alignment pattern error event is generated. This error event is captured by the CMFERI bit. 3. CRC-4 Error: When the local calculated CRC-4 of the current received CRC Sub Multi-Frame does not match the received CRC-4 of the next received CRC Sub Multi-Frame, a single CRC-4 error event is generated. This error event is captured by the CRCEI bit and is forwarded to the Performance Monitor. 4. Excessive CRC-4 Error: Once the accumulated CRC-4 errors are not less than 915 occasions (915 is included) in a 1 second fixed window, an excessive CRC-4 error event is generated. This error event is captured by the EXCRCERI bit. 5. CAS Signaling Multi-Frame Alignment Pattern Error: The received Signaling Multi-Frame alignment signals are compared with the expected ones (`0000'). When one or more bits do not match, a single CAS Signaling Multi-Frame alignment pattern error event is generated. This error event is captured by the SMFERI bit. 6. Far End Block Error (FEBE): When any of the CRC error indication (E1 or E2) bits is received as a logic 0, a far end block error event is generated. This error event is captured by the FEBEI bit and is forwarded to the Performance Monitor. 7. Continuous RAI & FEBE Error: When a logic 1 is received in the A bit and a logic 0 is received in any of the E1 or E2 bit for 10 ms, the RAICRCV bit is set. This bit is cleared if any of the conditions is not met. 8. Continuous FEBE Error: When a logic 0 is received in any of the E1 or E2 bits on 990 occasions per second for the latest 5 consecutive seconds, the CFEBEV bit is set, otherwise this bit will be cleared. 9. NT FEBE Error (per ETS 300 233): If the 4-bit Sa6 codeword of a CRC Sub Multi-Frame is matched with `0001' or `0011', the Network Terminal Far End Block Error event is generated. This error event is captured by the TFEBEI bit and is forwarded to the Performance Monitor. for TS17 for TS2 F15 X1 RMAI Extra Bits for TS1 F2 Y 0 1 0 45 August 20, 2009 IDT82P2282 DUAL T1/E1/J1 LONG HAUL / SHORT HAUL TRANSCEIVER 3.8.2.3 10. NT CRC Error (per ETS 300 233): If the 4-bit Sa6 codeword of a CRC Sub Multi-Frame is matched with `0010' or `0011', the Network Terminal CRC Error event is generated. This error event is captured by the TCRCEI bit and is forwarded to the Performance Monitor. Overhead Extraction 3.8.2.3.1 International Bit Extraction The International bits (Si bits, refer to Table 18) are extracted to the Si[0:1] bits in the TS0 International / National register. The Si[0:1] bits in the TS0 International / National register are updated on the boundary of the associated FAS/NFAS frame and are held during out of Basic frame state. Various errors will lead to out of synchronization: 3.8.2.2.1 Out Of Basic Frame Synchronization If there is one or more bit errors in a FAS pattern, a FAS pattern error will occur. If the NFAS bit position is received as zero, a NFAS error will occur. Determined by the BIT2C bit, if this bit is `0', 3 consecutive FAS pattern errors lead to out of Basic frame synchronization; if this bit is `1', 3 consecutive FAS pattern errors or 3 consecutive NFAS errors lead to out of Basic frame synchronization. Then if the REFEN bit is `1', the Frame Processor will start to search for synchronization again. Additionally, Excessive CRC-4 Error also leads to out of Basic frame synchronization. In this condition, both the REFEN bit being `1' and the REFCRCE bit being `1' will allow the Frame Processor to search for synchronization again. If the REFEN bit is `0', no error can lead to reframe except for manually setting. The manual reframe searches from Basic frame and is executed by a transition from `0' to `1' on the REFR bit. During out of Basic frame synchronization state, the FAS/NFAS Bit/Pattern Error detection is suspended. Once resynchronized, if the new-found Basic frame alignment pattern position differs from the previous one, the change of frame alignment event is generated. This event is captured by the COFAI bit and is forwarded to the Performance Monitor. 3.8.2.3.2 Remote Alarm Indication Bit Extraction The Remote Alarm Indication bit (A bit, refer to Table 18) is extracted to the A bit in the TS0 International / National register. The A bit in the TS0 International / National register is updated on the boundary of the associated NFAS frame and is held during out of Basic frame state. 3.8.2.3.3 National Bit Extraction The National bits (Sa bits, refer to Table 18) are extracted to the Sa[4:8] bits in the TS0 International / National register. The Sa[4:8] bits in the TS0 International / National register are updated on the boundary of the associated NFAS frame and are held during out of Basic frame. 3.8.2.3.4 National Bit Codeword Extraction The five sets of the National Bit codewords (Sa4[1:4] to Sa8[1:4] in the CRC Sub Multi-Frame, refer to Table 18) are extracted to the corresponding SaX Codeword register. Here the `X' is from 4 through 8. The National Bit codeword extraction will be set to de-bounce if the SaDEB bit is set to `1'. Thus, the SaX Codeword registers are updated if the received National Bit codeword is the same for 2 consecutive CRC Sub Multi-Frames. Whether de-bounced or not, a change indication will be set in the SaXI bit (`X' is from 4 through 8) if the corresponding codeword in the SaX Codeword register differs from the previous one. The value in the SaX Codeword registers is held during out of CRC Multi-Frame synchronization state. 3.8.2.2.2 Out Of CRC Multi-Frame Synchronization The conditions introducing out of Basic frame synchronization will also cause out of CRC Multi-Frame synchronization. During out of CRC Multi-Frame synchronization state, the FAS/NFAS Bit/Pattern Error detection, CRC Multi-Frame Alignment Pattern Error detection, CRC-4 Error detection, Excessive CRC-4 Error detection, Far End Block Error detection, Continuous RAI & FEBE Error detection, Continuous FEBE Error detection, NT CRC Error detection and NT FEBE Error detection are suspended. 3.8.2.3.5 Extra Bit Extraction The Extra bits (X bits, refer to Figure 13) are extracted to the X[0:2] bits in the TS16 Spare register. The X[0:2] bits in the TS16 Spare register are updated at the first bit of the next CAS Signaling Multi-Frame and are held during out of CAS Signaling Multi-Frame state. 3.8.2.2.3 Out Of CAS Signaling Multi-Frame Synchronization The conditions introducing out of Basic frame synchronization will also cause out of CAS Signaling Multi-Frame synchronization. In addition, determined by the SMFASC bit and the TS16C bit, if the CAS Signaling Multi-Frame Alignment Pattern Error occurs or all the contents in TS16 are zeros, it is out of CAS Signaling Multi-Frame synchronization. Then no matter what the value in the REFEN bit is, the Frame Processor will search for the CAS Signaling Multi-Frame synchronization again only if the Basic frame is in synchronization. During out of CAS Signaling Multi-Frame synchronization state, the CAS Signaling Multi-Frame Alignment Pattern Error detection is suspended. 3.8.2.3.6 Remote Signaling Multi-Frame Alarm Indication Bit Extraction The Remote Signaling Multi-Frame Alarm Indication bit (Y bit, refer to Figure 13) are extracted to the Y bit in the TS16 Spare register.

When there is a transition (from `1' to `0' or from `0' to `1') on the Status bit, the corresponding Status Interrupt Indication bit will be set to `1' (If the Status bit does not exist, the source will cause its Status Interrupt Indication bit to `1' directly) and the Status Interrupt Indication bit will be cleared by a write signal. A `1' in the Status Interrupt Indication bit means an interrupt occurred. The interrupt will be reported by the INT pin if its Status Interrupt Enable bit is `1'. pared if the Sa6SYN bit is `1'. If a matched code is detected, the corresponding indication bit in the Sa6 Code Indication register will be set. 3.8.2.4 V5.2 Link The V5.2 link ID signal, i.e., 2 out of 3 sliding Sa7 bits being logic 0, is detected with the indication in the V52LINKV bit.

A `1' in the RMAII bit means there is an interrupt. The interrupt will be reported by the INT pin if the RMAIE bit is `1'. The criteria of RED alarm detection meet I.431. The RED alarm will be declared when out of Basic frame synchronization persists for 100 ms, and the RED alarm will be cleared when in Basic frame synchronization persists for 100 ms.

The AIS alarm will be declared when less than 3 zeros are detected in a 512-bit fixed window and it is out of Basic frame synchronization, and the AIS alarm will be cleared when more than 2 zeros are detected in a 512-bit fixed window. When the AISC bit is `1', the criteria meet G.775. The AIS alarm will be declared when less than 3 zeros are detected in each of 2 consecutive 512-bit fixed windows, and the AIS alarm will be cleared when more than 2 zeros are detected in each of 2 consecutive 512-bit fixed windows.

The Length Indication is valid when the M2 bit is zero: Length Indication = N - 1 (N is the number of byte). Otherwise, the Length Indication is zero. Figure 15. Overhead Indication In The FIFO The HDLC Receiver will be reset when there is a transition from `0' to `1' on the RRST bit. The reset will clear the FIFO, the PACK bit and the EMP bit. The FIFO depth is 128 bytes. The FIFO is accessed by the DAT[7:0] bits. When the overhead is read from the FIFO, it will be indicated by the PACK bit. When all valid HDLC blocks are pushed into the FIFO or all the blocks are read from the FIFO, it will be indicated by the EMP bit. The interrupt sources in this block are summarized in Table 30. When there are conditions meeting the interrupt sources, the corresponding Interrupt Indication bit will be set to `1' and the Interrupt Indication bit will be cleared by writing a `1'. A `1' in the Interrupt Indication bit means there is an interrupt. The interrupt will be reported by the INT pin if its Interrupt Enable bit is `1'.

The BOM pattern is `111111110XXXXXX0' which occupies the DL of the F-bit in the ESF format (refer to Table 13). The six `X's represent the message. The BOM is declared only when the pattern is matched and the received message is identical 4 out of 5 consecutive times or 8 out of 10 consecutive times and differs from the previous message. The identification time is selected by the AVC bit. After a new BOM is declared, the message is loaded into the BOC[5:0] bits. Every time when the BOC[5:0] bits are updated, it will be indicated by the BOCI bit. A `1' in the BOCI bit means there is an interrupt. The interrupt will be reported by the INT pin if the BOCE bit is `1'. In BITS application, network timing recovery is required. In addition to timing recovery, the incoming line can carry Synchronization Status Messages, or SSM, to indicate the quality level of the incoming clock. SSM (in code words) are transmitted and/or received through the data link bits (DS1 ESF formats) in T1/J1 mode. XBOC[5:0] and BOC[5:0] mode can be used to transmit and receive the code words of SSM, respectively. In E1 mode, Sa bits in Time Slot 0 can be used for transmit or receive SSM code words. In T1/J1 ESF mode, the BOC[5:0] bits can be used to hold the received codeword in SSM application. The XBOC[5:0] bits, on the other hand, can be used to transmit the SSM codeword to the network far end. In E1 mode, each of the Sa[4:8] bits can be used for the same purpose. For example, if the Sa[4] bit is used in transmit direction, SSM is transmitted by using the Sa[4] bit; in receive direction, the E1 Sa4 Codeword Register contains the received SSM codeword. The Inband Loopback Code Detector tracks the loopback activate/ deactivate codes only in framed or unframed T1/J1 data stream, and meets ANSI T1.403 9.3.1. The received data stream is compared with the target activate/ deactivate code whose length and content are programmed in the ASEL[1:0]/DSEL[1:0] bits and the ACT[7:0]/DACT[7:0] bits respectively. In framed mode, the F-bit is selected by the IBCDIDLE bit to compare with the target activate/deactivate code or not. In unframed mode, all 193 bits are compared with the target activate/deactivate code. After four consecutive correct activate/deactivate codes are found in the received data stream, the Inband Loopback Code Detector keeps on monitoring the bit error, i.e., the bit differs from the target activate/ deactivate code. If in more than 126 consecutive 39.8ms fixed periods, less than 600 bit errors are detected in each 39.8ms, the activate/deactivate code is detected and the corresponding LBA/LBD bit will indicate it. Once more than 600 bit errors are detected in a 39.8ms fixed period, the activate/deactivate code is out of synchronization and the corresponding LBA/LBD bit will be cleared. However, even if the F-bit is compared, whether it is matched or not, the result will not cause bit errors, that is, the comparison result of the F-bit is discarded. Any transition (from `0' to `1' or from `1' to `0') on the LBA/LBD bit will set the LBAI/LBDI bit, which means there is an interrupt. The interrupt will be reported by the INT pin if the corresponding LBAE/LBDE bit is set to `1'.

A write pointer is used to write the data to the Elastic Store Buffer, while a read pointer is used to read the data from the Elastic Store Buffer. When the average frequency of the incoming data is greater than the average frequency of the (Multiplexed) Receive Side System Clock (RSCKn/MRSCK), the write pointer will be faster than the read pointer and the Elastic Store Buffer will be filled. Until there is less than or equal to 2 bytes between the write pointer and the read pointer, a frame will be deleted after its prior frame is read. When the read pointer crosses the frame boundary, a controlled slip will occur with a `1' indicated in the SLIPD bit. When the average frequency of the incoming data is less than the average frequency of the RSCKn/MRSCK, the write pointer will be slower than the read pointer and the Elastic Store Buffer will be empty. Until there is less than or equal to 2 bytes between the write pointer and the read pointer, the frame will be repeated after it is read. When the read pointer crosses the next frame boundary, a controlled slip will occur with a `0' indicated in the SLIPD bit. When the slip occurs, the SLIPI bit will indicate it. An interrupt on the INT pin will occur if the SLIPE bit is `1'. In Receive Clock Slave mode and Receive Multiplexed mode, if it is out of synchronization, the trunk code programmed in the TRKCODE[7:0] bits will be set to replace the data if the TRKEN bit is set to `1'. In Receive Clock Master mode, the Elastic Store Buffer is bypassed unless the device is in the Payload Loopback diagnosis mode (refer to Chapter 3.27.2.2 Payload Loopback). The Receive CAS/RBS Buffer extracts the signaling bits from the received data stream. 3.15.1 T1/J1 MODE In SF/ESF/SLC-96 format, the signaling bits are located in the Bit 8 of Frame 6n (n = 1,2 in SF format; 1 n 4 in ESF format; 1 n 12 in SLC-96 format) (refer to Table 12, Table 13 and Table 15 respectively). The signaling codewords (AB or ABCD) are clocked out on the RSIGn/ MRSIG pins. They are in the lower nibble of the channel with its corresponding data serializing on the RSDn/MRSD pins (as shown in Figure 16). When the EXTRACT bit is set to `1', the signaling bits in its corresponding channel are extracted to the A,B,C,D bits in the Extracted Signaling Data/Extract Enable register. In SF format, the C,D bits in the register are the repetition of the signaling bits A,B. The data in the A,B,C,D bits in the Extracted Signaling Data/Extract Enable register are the data to be output on the RSIGn/MRSIG pins. However, in T1-DM format, there is no signaling bits. Signaling de-bounce will be executed when the DEB bit is set to `1'. Thus, the A,B,C,D bits in the Extracted Signaling Data/Extract Enable register are updated only if 2 consecutive received AB/ABCD codewords of the same channel are identical. Signaling freezing is performed automatically when it is out of frame synchronization or when slips occurs in the Elastic Store Buffer. It is also performed when the FREEZE bit is set to `1'. The signaling freezing freezes the signaling data in the A,B,C,D bits in the Extracted Signaling Data/Extract Enable register as the previous valid value. In the ESF and SLC-96 format, if the SIGF bit is set to `0', the extracted signaling bits are in 4 states signaling, i.e., the signaling bits on Framer 6 & 18 of a signaling multi-frame are recognized as `A' and the signaling bits on Framer 12 & 24 are recognized as `B'. Only the signaling bits A & B will be saved in the Extracted Signaling Data/Extract Enable register, and the C & D bits in the Extracted Signaling Data/ Extract Enable register are Don't-Care. If the SIGF bit is set to `1', the extracted signaling bits are in 16 states signaling, i.e., four signaling bits A, B, C & D are all saved in the Extracted Signaling Data/Extract Enable register. Each time the extracted signaling bits stored in the Extracted Signaling Data/Extract Enable register are changed, it is captured by the corresponding COSI[X] bit (1 X 24). When the SIGE bit is set to `1', any one of the COSI[X] bits being `1' will generate an interrupt and will be reported by the INT pin. The EXTRACT bit and the A,B,C,D bits are in the indirect registers of the Receive CAS/RBS Buffer. They are accessed by specifying the address in the ADDRESS[6:0] bits. Whether the data is read from or written into the specified indirect register is determined by the RWN bit and the data is in the D[7:0] bits. The access status is indicated in the BUSY bit. Refer to Chapter 4.5 Indirect Register Access Scheme for details about the indirect registers write/read access.

When the SIGE bit is set to `1', any one of the COSI[X] bits being `1' will generate an interrupt and will be reported by the INT pin. The EXTRACT bit and the A,B,C,D bits are in the indirect registers of the Receive CAS/RBS Buffer. They are accessed by specifying the address in the ADDRESS[6:0] bits.

Refer to Chapter 4.5 Indirect Register Access Scheme for details about the indirect registers write/read access. 3.15.2 E1 MODE In Signaling Multi-Frame, the signaling bits are located in TS16 (refer to Figure 13), which are Channel Associated Signalings (CAS). The signaling codewords (ABCD) are clocked out on the RSIGn/MRSIG pins. They are in the lower nibble of the timeslot with its corresponding data serializing on the RSDn/MRSD pins (as shown in Figure 17). When the EXTRACT bit is set to `1', the signaling bits in its corresponding timeslot are extracted to the A,B,C,D bits in the Extracted Signaling Data/Extract Enable register. The data in the A,B,C,D bits in the register are the data to be output on the RSIGn/MRSIG pins. The bits corresponding to TS0 and TS16 output on the RSIGn/MRSIG pins are Don't-Care.

To enable all the functions in the Receive Payload Control, the PCCE bit must be set to `1'. The following methods can be executed on the data to be output on the RSDn/MRSD pins on a per-channel/per-TS basis or on a global basis of the corresponding link (the methods are arranged from the highest to the lowest in priority): - When the TESTEN bit is enabled and the PRBSDIR bit is `0', the received data will be extracted to the PRBS Generator/Detector. The received data can be extracted in unframed mode, in 8-bit-based mode or in 7-bit-based mode. This selection is made by the PRBSMODE[1:0] bits. In unframed mode, all the received data stream is extracted and the per-channel/per-TS configuration in the TEST bit is ignored. In 8-bitbased mode or in 7-bit-based mode, the received data will only be extracted on the channel/timeslot configured by the TEST bit. Refer to Chapter 3.27.1 PRBS Generator / Detector for details. - Selected by the GSUBST[2:0] bits, the data of all channels/ timeslots of the corresponding link will be replaced by the data trunk code set in the DTRK[7:0] bits, or the milliwatt pattern defined in the Table 36 and Table 37. When the GSUBST[2:0] bits are set to `000', these replacements will be performed on a per-channel/per-TS basis by setting the SUBST[2:0] bits in the corresponding channel/timeslot. - When the SIGFIX bit is set to `1', the signaling bits (ABCD) will be fixed to the value set in the POL bit. This function is only supported in the SF, ESF and SLC-96 formats in T1/J1 mode. - Invert the most significant bit, the even bits and/or the odd bits by setting the SINV, OINV, EINV bits. - When the TESTEN bit is enabled and the PRBSDIR bit is `1', the received data will be replaced by the test pattern generated from the PRBS Generator/Detector. The received data can be replaced in unframed mode, in 8-bit-based mode or in 7-bit-based mode. This selection is made by the PRBSMODE[1:0] bits. In unframed mode, all the received data stream is replaced and the per-channel/per-TS configuration in the TEST bit is ignored.

This clock is derived from line side signal or MCLK (When LOSS). In the Receive Clock Master mode, if RSCKn outputs pulses during the entire T1/J1 frame, the Receive System Interface is in Receive Clock Master Full T1/J1 mode. If only the clocks aligned to the selected channels are output on RSCKn, the Receive System Interface is in Receive Clock Master Fractional T1/J1 mode. In the Receive Clock Slave mode, outside inputs clock (M)RSCKn/ (M)RSFSn to the device. To avoid shatter data, this clock should keep the same source with line side. If the backplane data rate is 2.048 Mb/s, means T1 mode E1 rate, the receive data(1.544 Mb/s) should be mapped to 2.048 Mb/s,there are 3 kinds of mapping schemes. In the Receive Multiplexed mode, since the received data from the two links should be converted to 2.048 Mb/s format first and then multiplexed to 8.192 Mb/s, there are still 3 kinds of schemes to be selected. Table 39 summarizes how to set the Receive System Interface of each link into various operating modes and the pins' direction of the Receive System Interface in different operating modes. The Receive System Interface determines how to output the received data stream to the system backplane. The data from the two links can be aligned with each other or be output independently. The timing clocks and framing pulses can be provided by the system backplane or obtained from the far end. The Receive System Interface supports various configurations to meet various requirements in different applications. 3.17.1 T1/J1 MODE In T1/J1 mode, the Receive System Interface can be set in Nonmultiplexed Mode or Multiplexed Mode. In the Non-multiplexed Mode, the RSDn pin is used to output the received data from each link at the bit rate of 1.544 Mb/s or 2.048 Mb/s (T1/J1 mode E1 rate). While in the Multiplexed Mode, the received data from the two links is converted to 2.048 Mb/s format and byte interleaved to form one high speed data stream and output on the MRSD pin at the bit rate of 8.192 Mb/s.

The active polarity of the RSFSn is selected by the FSINV bit. The Receive Clock Master mode includes two sub-modes: Receive Clock Master Full T1/J1 mode and Receive Clock Master Fractional T1/ J1 mode. 3.17.1.1 Receive Clock Master Mode In the Receive Clock Master mode, each link uses its own timing signal on the RSCKn pin and framing pulse on the RSFSn pin to output the data on each RSDn pin. The signaling bits on the RSIGn pin are perchannel aligned with the data on the RSDn pin. In the Receive Clock Master mode, the data on the system interface is clocked by the RSCKn. The active edge of the RSCKn used to update the pulse on the RSFSn is determined by the FE bit. The active edge of the RSCKn used to update the data on the RSDn and RSIGn is determined by the DE bit. If the FE bit and the DE bit are not equal, the pulse on the RSFSn is ahead. In the Receive Clock Master mode, the RSFSn can indicate each F-bit or the first F-bit of every SF/ESF/T1 DM/SLC-96 multi-frame.

All the indications are selected by the Functional Description 3.17.1.1.1 Receive Clock Master Full T1/J1 Mode Besides all the common functions described in the Receive Clock Master mode, the special feature in this mode is that the RSCKn is a standard 1.544 MHz clock, and the data in the F-bit and all 24 channels in a standard T1/J1 frame are clocked out by the RSCKn. 65 August 20, 2009 IDT82P2282 DUAL T1/E1/J1 LONG HAUL / SHORT HAUL TRANSCEIVER tem side. The F-bit of Frame N from the device is converted into the first bit of TS26 of Frame (N-1) on the system side.

T1/J1 Mode E1 Rate per One Filler Every Fourth CH (refer to Figure 19): One dummy byte is inserted on the system side before 3 bytes of Frame N from the device are converted. This process repeats 8 times and the conversion of Frame N of 1.544 Mb/s data rate to 2.048 Mb/s data rate is completed. However, the F-bit of Frame N of the 1.544 Mb/s data rate is inserted as the 8th bit of Frame N of the 2.048 Mb/s data rate. The dummy bytes are filled with all `0's and they are meaningless. 3. T1/J1 Mode E1 Rate per Continuous CHs (refer to Figure 20): Channel 1 to Channel 24 of Frame N from the device are converted into TS1 to TS24 of Frame N on the system side. The F-bit of Frame N from the device is converted into the 8th bit of Frame N on the system side. The first 7 bits and TS25 to TS31 on the system side are all filled with `0's and they are meaningless. 3.17.1.1.2 Receive Clock Master Fractional T1/J1 Mode Besides all the common functions described in the Receive Clock Master mode, the special feature in this mode is that the RSCKn is a gapped 1.544 MHz clock (no clock signal during the selected position). The RSCKn is gapped during the F-bit if the FBITGAP bit is set to `1'. The RSCKn is also gapped during the channels or the Bit 8 duration by selecting the G56K & GAP bits in the Receive Payload Control. The data in the corresponding gapped duration is a don't care condition. 3.17.1.2 Receive Clock Slave Mode In the Receive Clock Slave mode, the system data rate can be 1.544 Mb/s or 2.048 Mb/s. If the system data rate is 1.544 Mb/s, it works in T1/J1 mode. If the system data rate is 2.048 Mb/s, the received data stream (1.544 Mb/s) should be mapped to the same rate as the system side, that is, to work in T1/J1 mode E1 rate.

T1/J1 To E1 Format Mapping - Continuous Channels Mode interleaved output on the multiplexed bus. When the data from the two links is output on one multiplexed bus, the sequence of the data is arranged by setting the channel offset. The data from different links on one multiplexed bus must be shifted at a different channel offset to avoid data mixing. In the Receive Multiplexed mode, the timing signal on the MRSCK pin and the framing pulse on the MRSFS pin are provided by the system side and common to both two links. The signaling bits on the MRSIG pin are per-channel aligned with the corresponding data on the MRSD pin. In the Receive Multiplexed mode, the data on the system interface is clocked by the MRSCK. The active edge of the MRSCK used to sample the pulse on the MRSFS is determined by the FE bit. The active edge of the MRSCK used to update the data on the MRSD and MRSIG is determined by the DE bit. The FE bit and the DE bit of the two links should be set to the same value respectively. If the FE bit and the DE bit are not equal, the pulse on the MRSFS is ahead. The MRSCK can be selected by the CMS bit to be the same rate as the data rate on the system side (8.192 MHz) or double the data rate (16.384 MHz). The CMS bit of the two links should be set to the same value. If the speed of the MRSCK is double the data rate, there will be two active edges in one bit duration. In this case, the EDGE bit determines the active edge to update the data on the MRSD and MRSIG pins. The pulse on the MRSFS pin is always sampled on its first active edge. In the Receive Multiplexed mode, the MRSFS asserts at a rate of integer multiple of 125 s to indicate the start of a frame. The active polarity of the MRSFS is selected by the FSINV bit. The FSINV bit of the two links should be set to the same value. If the pulse on the MRSFS pin is not an integer multiple of 125 s, this detection will be indicated by the RCOFAI bit. If the RCOFAE bit is enabled, an interrupt will be reported by the INT pin when the RCOFAI bit is `1'. In the Receive Clock Slave mode, the timing signal on the RSCKn pin and the framing pulse on the RSFSn pin to output the data on the RSDn pin are provided by the system side. When the RSLVCK bit is set to `0', each link uses its own RSCKn and RSFSn; when the RSLVCK bit is set to `1' and both two links are in the Receive Clock Slave mode, the two links use the RSCK[1] and RSFS[1] to output the data. The signaling bits on the RSIGn pin are per-channel aligned with the data on the RSDn pin. In the Receive Clock Slave mode, the data on the system interface is clocked by the RSCKn. The active edge of the RSCKn used to sample the pulse on the RSFSn is determined by the FE bit. The active edge of the RSCKn used to update the data on the RSDn and RSIGn is determined by the DE bit. If the FE bit and the DE bit are not equal, the pulse on the RSFSn is ahead. The data rate of the system side is 1.544 Mb/s or 2.048 Mb/s. When it is 2.048 Mb/s, the RSCKn can be selected by the CMS bit to be the same rate as the data rate on the system side (2.048 MHz) or double the data rate (4.096 MHz). If both two links use the RSCK[1] and RSFS[1] to output the data, the CMS bit of the two links should be set to the same value. If the speed of the RSCKn is double the data rate, there will be two active edges in one bit duration. In this case, the EDGE bit determines the active edge to update the data on the RSDn and RSIGn pins. The pulse on the RSFSn pin is always sampled on its first active edge. In the Receive Clock Slave mode, the RSFSn asserts at a rate of integer multiple of 125 s to indicate the start of a frame. The active polarity of the RSFSn is selected by the FSINV bit. If the pulse on the RSFSn pin is not an integer multiple of 125 s, this detection will be indicated by the RCOFAI bit. If the RCOFAE bit is enabled, an interrupt will be reported by the INT pin when the RCOFAI bit is `1'. 3.17.1.3 Receive Multiplexed Mode In the Receive Multiplexed mode, since the received data from the two links should be mapped to 2.048 Mb/s format first, the 3 kinds of schemes should be selected by the MAP[1:0] bits. The mapping per G.802, per One Filler Every Four CHs and per Continuous CHs are the same as the description in Chapter 3.17.1.2 Receive Clock Slave Mode. In the Receive Multiplexed mode, a multiplexed bus is used to output the data from both two links. The data of Link 1 to Link 2 is byte- Functional Description 3.17.1.4 Offset Bit offset and channel offset are both supported in all the operating modes. The offset is between the framing pulse on RSFSn/MRSFS pin and the start of the corresponding frame output on the RSDn/MRSD pin. The signaling bits on the RSIGn/MRSIG pin are always per-channel aligned with the data on the RSDn/MRSD pin.

No Offset When FE = 1 & DE = 0 In Receive Path When the CMS bit is `1' (i.e., in double clock mode) and the BOFF[2:0] bits are set, the start of the corresponding frame output on the RSDn/MRSD pin will delay `2 x N' clock cycles to the framing pulse on the RSFSn/MRSFS pin. (Here `N' is defined by the BOFF[2:0] bits.) When the CMS bit is `1' (i.e., in double clock mode) and the TSOFF[6:0] bits are set, the start of the corresponding frame output on the RSDn/ MRSD pin will delay `16 x M' clock cycles to the framing pulse on the RSFSn/MRSFS pin. (Here `M' is defined by the TSOFF[6:0].) The bit offset and channel offset are configured when the BOFF[2:0] bits and the TSOFF[6:0] bits are not `0' respectively. When the CMS bit is `0' and the BOFF[2:0] bits are set, the start of the corresponding frame output on the RSDn/MRSD pin will delay `N' clock cycles to the framing pulse on the RSFSn/MRSFS pin. (Here `N' is defined by the BOFF[2:0] bits.) When the CMS bit is `0' and the TSOFF[6:0] bits are set, the start of the corresponding frame output on the RSDn/MRSD pin will delay `8 x M' clock cycles to the framing pulse on the RSFSn/MRSFS pin.

Functional Description 69 August 20, 2009 IDT82P2282 DUAL T1/E1/J1 LONG HAUL / SHORT HAUL TRANSCEIVER 3.17.2 E1 MODE In E1 mode, the Receive System Interface can be set in Non-multiplexed Mode or Multiplexed Mode. In the Non-multiplexed Mode, the RSDn pin is used to output the received data from each link at the bit rate of 2.048 Mb/s. While in the Multiplexed Mode, the received data from the two links is byte interleaved to form one high speed data stream and output on the MRSD pin at the bit rate of 8.192 Mb/s. In the Non-multiplexed mode, if the RSCK is from outside, the receive system interface is in Receive Clcok Slave mode, otherwise if the device outputs clock to RSCK from itself, the receive system interface is in Receive Clcok Master mode. In the Receive Clock Master mode, if RSCKn outputs pulses during the entire E1 frame, the Receive System Interface is in Receive Clock Master Full E1 mode. If only the clocks aligned to the selected timeslots are output on RSCKn, the Receive System Interface is in Receive Clock Master Fractional E1 mode. Table 40 summarizes how to set the receive system interface of each link into various operating modes and the pins' direction of the receive system interface in different operating modes. In Non-multiplexed mode, the channel offset can be configured from 0 to 23 channels (0 & 23 are included). In Multiplexed mode, the channel offset can be configured from 0 to 127 channels (0 & 127 are included). 3.17.1.5 Output On RSDn/MRSD & RSIGn/MRSIG The output on the RSDn/MRSD and the RSIGn/MRSIG pins can be configured by the TRI bit of the corresponding link to be in high impedance state or to output the processed data stream.

When the G56K, GAP bits in RPLC indirect registers are set, the PCCE bit must be set to `1'. 3.17.2.1.1 Receive Clock Master Full E1 Mode Besides all the common functions described in the Receive Clock Master mode, the special feature in this mode is that the RSCKn is a standard 2.048 MHz clock, and the data in all 32 timeslots in a standard E1 frame is clocked out by the RSCKn. 3.17.2.1 Receive Clock Master Mode In the Receive Clock Master mode, each link uses its own timing signal on the RSCKn pin and framing pulse on the RSFSn pin to output the data on each RSDn pin. The signaling bits on the RSIGn pin are pertimeslot aligned with the data on the RSDn pin. In the Receive Clock Master mode, the data on the system interface is clocked by the RSCKn. The active edge of the RSCKn used to update the pulse on the RSFSn is determined by the FE bit. The active edge of the RSCKn used to update the data on the RSDn and RSIGn is determined by the DE bit. If the FE bit and the DE bit are not equal, the pulse on the RSFSn is ahead. In the Receive Clock Master mode, the RSFSn can indicate the Basic frame, CRC Multi-frame, Signaling Multi-frame, or both the CRC Multi-frame and Signaling Multi-frame, or the TS1 and TS 16 overhead. All the indications are selected by the OHD bit, the SMFS bit and the CMFS bit. The active polarity of the RSFSn is selected by the FSINV bit. The Receive Clock Master mode includes two sub-modes: Receive Clock Master Full E1 mode and Receive Clock Master Fractional E1 mode. Functional Description 3.17.2.1.2 Receive Clock Master Fractional E1 Mode Besides all the common functions described in the Receive Clock Master mode, the special feature in this mode is that the RSCKn is a gapped 2.048 MHz clock (no clock signal during the selected timeslot). The RSCKn is gapped during the timeslots or the Bit 8 duration by selecting the G56K & GAP bits in the Receive Payload Control. The data in the corresponding gapped duration is a don't care condition. 3.17.2.2 Receive Clock Slave Mode In the Receive Clock Slave mode, the timing signal on the RSCKn pin and framing pulse on the RSFSn pin to output the data on the RSDn pin are provided by the system side. When the RSLVCK bit is set to `0', each link uses its own RSCKn and RSFSn; when the RSLVCK bit is set to `1' and both two links are in the Receive Clock Slave mode, the two links use the RSCK[1] and RSFS[1] to output the data.

In the Receive Clock Slave mode, the data on the system interface is clocked by the RSCKn. The active edge of the RSCKn used to sample the pulse on the RSFSn is determined by the FE bit. The active edge of the RSCKn used to update the data on the RSDn and RSIGn is determined by the DE bit. If the FE bit and the DE bit are not equal, the pulse on the RSFSn is ahead. The speed of the RSCKn can be selected by the CMS bit to be the same rate as the data rate on the system side (2.048 MHz) or double the data rate (4.096 MHz). If both two links use the RSCK[1] and RSFS[1] to output the data, the CMS bit of the two links should be set to the same value. If the speed of the RSCKn is double the data rate, there will be two active edges in one bit duration. In this case, the EDGE bit determines the active edge to update the data on the RSDn and RSIGn pins. The pulse on the RSFSn pin is always sampled on its first active edge. In the Receive Clock Slave mode, the RSFSn asserts at a rate of integer multiple of 125 s to indicate the start of a frame. The active polarity of the RSFSn is selected by the FSINV bit. If the pulse on the RSFSn pin is not an integer multiple of 125 s, this detection will be indicated by the RCOFAI bit. If the RCOFAE bit is enabled, an interrupt will be reported by the INT pin when the RCOFAI bit is `1'. 3.17.2.4 Offset Except that in the Receive Master mode, when the OHD bit, the SMFS bit and the CMFS bit are set to TS1 and TS16 overhead indication, the bit offset and timeslot offset are both supported in all the other conditions. The offset is between the framing pulse on RSFSn/MRSFS pin and the start of the corresponding frame output on the RSDn/MRSD pin. The signaling bits on the RSIGn/MRSIG pin are always per-timeslot aligned with the data on the RSDn/MRSD pin. Refer to Chapter 3.17.1.4 Offset for the base line without offset in different operating modes and the configuration of the offset. In Non-multiplexed mode, the timeslot offset can be configured from 0 to 31 timeslots (0 & 31 are included). In Multiplexed mode, the timeslot offset can be configured from 0 to 127 timeslots (0 & 127 are included). 3.17.2.5 Output On RSDn/MRSD & RSIGn/MRSIG The output on the RSDn/MRSD and the RSIGn/MRSIG pins can be configured by the TRI bit of the corresponding link to be in high impedance state or to output the processed data stream. 3.17.2.3 Receive Multiplexed Mode In the Receive Multiplexed mode, one multiplexed bus is used to output the data from both two links. The data of Link 1 to Link 2 is byteinterleaved output on the multiplexed bus. When the data from the two links is output on one multiplexed bus, the sequence of the data is arranged by setting the timeslot offset. The data from different links on one multiplexed bus must be shifted at a different timeslot offset to avoid data mixing. In the Receive Multiplexed mode, the timing signal on the MRSCK pin and the framing pulse on the MRSFS pin are provided by the system side and common to both two links. The signaling bits on the MRSIG pin are per-timeslot aligned with the corresponding data on the MRSD pin. In the Receive Multiplexed mode, the data on the system interface is clocked by the MRSCK. The active edge of the MRSCK used to sample the pulse on the MRSFS is determined by the FE bit. The active edge of the MRSCK used to update the data on the MRSD and MRSIG is determined by the DE bit. The FE bit and the DE bit of the two links should be set to the same value respectively. If the FE bit and the DE bit are not equal, the pulse on the MRSFS is ahead. The MRSCK can be selected by the CMS bit to be the same rate as the data rate on the system side (8.192 MHz) or double the data rate (16.384 MHz). The CMS bit of the two links should be set to the same value. If the speed of the MRSCK is double the data rate, there will be two active edges in one bit duration. In this case, the EDGE bit determines the active edge to update the data on the MRSD and MRSIG pins. The pulse on the MRSFS pin is always sampled on its first active edge. In the Receive Multiplexed mode, the MRSFS asserts at a rate of integer multiple of 125 s to indicate the start of a frame. The active polarity of the MRSFS is selected by the FSINV bit. The FSINV bit of the two links should be set to the same value.

In the Transmit Clock Master mode, if TSCKn outputs pulses during the entire T1/J1 frame, the Transmit System Interface is in Transmit Clock Master Full T1/J1 mode. If only the clocks aligned to the selected channels are output on TSCKn, the Transmit System Interface is in Transmit Clock Master Fractional T1/J1 mode. In the Transmit Clock Slave mode, the backplane data rate may be equal to 1.544 Mb/s (i.e., the line data rate) or 2.048 Mb/s or 8.192 Mb/s. If the backplane data rate is 2.048 Mb/s or 8.192 Mb/s, the Transmit System Interface is in T1/J1 mode E1 rate and the data to be transmitted will be mapped to 1.544 Mb/s i device per 3 kinds of schemes. Table 42 summarizes how to set the transmit system interface of each link into various operating modes and the pins' direction of the transmit system interface in different operating modes. The Transmit System Interface determines how to input the data to the device. The data input to the two links can be aligned with each other or input independently. The timing clocks and framing pulses can be provided by the system backplane or obtained from the processed data of each link. The Transmit System Interface supports various configurations to meet various requirements in different applications. 3.18.1 T1/J1 MODE In T1/J1 mode, the Transmit System Interface can be set in Nonmultiplexed Mode or Multiplexed Mode. In the Non-multiplexed Mode, the TSDn pin is used to input the data to each link at the bit rate of 1.544 Mb/s or 2.048 Mb/s (T1/J1 mode E1 rate). While in the Multiplexed Mode, the data is byte-interleaved from one high speed data stream and inputs on the MTSD pin at the bit rate of 8.192 Mb/s. The demultiplexed data input to the two links is 2.048 Mb/s on the system side and converted into 1.544 Mb/s format to the device.

The Transmit Clock Master mode includes two sub-modes: Transmit Clock Master Full T1/J1 mode and Transmit Clock Master Fractional T1/J1 mode. 3.18.1.1 Transmit Clock Master Mode In the Transmit Clock Master mode, each link uses its own timing signal on the TSCKn pin and framing pulse on the TSFSn pin to input the data on each TSDn pin. The signaling bits on the TSIGn pin are perchannel aligned with the data on the TSDn pin. In the Transmit Clock Master mode, the data on the system interface is clocked by the TSCKn. The active edge of the TSCKn used to update the pulse on the TSFSn is determined by the FE bit. The active edge of the TSCKn used to sample the data on the TSDn and TSIGn is determined by the DE bit. If the FE bit and the DE bit are not equal, the pulse on the TSFSn is ahead. In the Transmit Clock Master mode, the TSFSn can indicate each F-bit or the first F-bit of every SF/ESF/T1 DM/SLC-96 multi-frame. The indications are selected by the FSTYP bit. The active polarity of the TSFSn is selected by the FSINV bit. 3.18.1.1.1 Transmit Clock Master Full T1/J1 Mode Besides all the common functions described in the Transmit Clock Master mode, the special feature in this mode is that the TSCKn is a standard 1.544 MHz clock, and the data in the F-bit and all 24 channels in a standard T1/J1 frame are clocked in by the TSCKn. 3.18.1.1.2 Transmit Clock Master Fractional T1/J1 Mode Besides all the common functions described in the Transmit Clock Master mode, the special feature in this mode is that the TSCKn is a gapped 1.544 MHz clock (no clock signal during the selected channel). The TSCKn is gapped during the F-bit if the FBITGAP bit is set to `1'. The TSCKn is also gapped during the channels or the Bit 8 duration 73 August 20, 2009 IDT82P2282 DUAL T1/E1/J1 LONG HAUL / SHORT HAUL TRANSCEIVER verted into the F-bit of Frame N to the device.

The data in the corresponding gapped duration is a Don't Care condition. 3.18.1.2 Transmit Clock Slave Mode In the Transmit Clock Slave mode, the system data rate can be 1.544 Mb/s or 2.048 Mb/s. If the system data rate is 1.544 Mb/s, it works in T1/J1 mode. If the system data rate is 2.048 Mb/s, the data stream to be transmitted should be mapped to 1.544 Mb/s, that is, to work in T1/J1 mode E1 rate. Three kinds of schemes are provided by selecting the MAP[1:0] bits: 1.

E1 To T1/J1 Format Mapping - Continuous Channels Mode In the Transmit Multiplexed mode, one multiplexed bus is used to transmit the data to both two links. The data of Link 1 to Link 2 is byteinterleaved input from the multiplexed bus. When the data on the multiplexed bus is input to two links, the sequence of the data is arranged by setting the channel offset. The data to different links from one multiplexed bus must be shifted at a different channel offset to avoid data mixing. In the Transmit Multiplexed mode, the timing signal on the MTSCK pin and the framing pulse on the MTSFS pin are provided by the system side and common to allboth two links. The signaling bits on the MTSIG pin are per-channel aligned with the corresponding data on the MTSD pin. In the Transmit Multiplexed mode, the data on the system interface is clocked by the MTSCK. The active edge of the MTSCK used to sample the pulse on the MTSFS is determined by the FE bit. The active edge of the MTSCK used to sample the data on the MTSD and MTSIG is determined by the DE bit. The FE bit and the DE bit of the two links should be set to the same value respectively. If the FE bit and the DE bit are not equal, the pulse on the MTSFS is ahead. The MTSCK can be selected by the CMS bit to be the same rate as the data rate on the system side (8.192 MHz) or double the data rate (16.384 MHz). The CMS bit of the two links should be set to the same value. If the speed of the MTSCK is double the data rate, there will be two active edges in one bit duration. In this case, the EDGE bit determines the active edge to sample the data on the MTSD and MTSIG pins. The pulse on the MTSFS pin is always sampled on its first active edge. In the Transmit Multiplexed mode, the MTSFS can indicate each Fbit of the first link or the first F-bit of every SF/ESF/T1 DM/SLC-96 multiframe of the first link. The indications are selected by the FSTYP bit. The active polarity of the MTSFS is selected by the FSINV bit. The FSTYP bit and the FSINV bit of the two links should be set to the same value. If the pulse on the MTSFS pin is not an integer multiple of 125 s, this detection will be indicated by the TCOFAI bit. If the TCOFAE bit is enabled, an interrupt will be reported by the INT pin when the TCOFAI bit is `1'. In the Transmit Clock Slave mode, the timing signal on the TSCKn pin and the framing pulse on the TSFSn pin to input the data on the TSDn pin are provided by the system side. When the TSLVCK bit is set to `0', each link uses its own TSCKn and TSFSn; when the TSLVCK bit is set to `1' and both two links are in the Transmit Clock Slave mode, the two links use the TSCK[1] and TSFS[1] to input the data. The signaling bits on the TSIGn pin are per-channel aligned with the data on the TSDn pin. In the Transmit Clock Slave mode, the data on the system interface is clocked by the TSCKn. The active edge of the TSCKn used to sample the pulse on the TSFSn is determined by the FE bit. The active edge of the TSCKn used to sample the data on the TSDn and TSIGn is determined by the DE bit. If the FE bit and the DE bit are not equal, the pulse on the TSFSn is ahead. The data rate of the system side is 1.544 Mb/s or 2.048 Mb/s. When it is 2.048 Mb/s, the TSCKn can be selected by the CMS bit to be the same rate as the data rate on the system side (2.048 MHz) or double the data rate (4.096 MHz). If both two links use the TSCK[1] and TSFS[1] to input the data, the CMS bit of the two links should be set to the same value. If the speed of the TSCKn is double the data rate, there will be two active edges in one bit duration. In this case, the EDGE bit determines the active edge to sample the data on the TSDn and TSIGn pins. The pulse on the TSFSn pin is always sampled on its first active edge. In the Transmit Clock Slave mode, the TSFSn can indicate each Fbit or the first F-bit of every SF/ESF/T1 DM/SLC-96 multi-frame. The indications are selected by the FSTYP bit. The active polarity of the TSFSn is selected by the FSINV bit. If the pulse on the TSFSn pin is not an integer multiple of 125 s, this detection will be indicated by the TCOFAI bit. If the TCOFAE bit is enabled, an interrupt will be reported by the INT pin when the TCOFAI bit is `1'. 3.18.1.3 Transmit Multiplexed Mode In the Transmit Multiplexed mode, since the demultiplexed data rate on the system side (2.048 Mb/s) should be mapped to the data rate in the line side (1.544 Mb/s), 3 kinds of schemes should be selected by the MAP[1:0] bits. The schemes per G.802, per One Filler Every Four CHs and per Continuous CHs are the same as the description in Chapter 3.18.1.2 Transmit Clock Slave Mode. 75 August 20, 2009 IDT82P2282 DUAL T1/E1/J1 LONG HAUL / SHORT HAUL TRANSCEIVER pin. The signaling bits on the TSIGn/MTSIG pin are always per-channel aligned with the data on the TSDn/MTSD pin. Figure 28 to Figure 31 show the base line without offset. 3.18.1.4 Offset Bit offset and channel offset are both supported in all the operating modes.

No Offset When FE = 1 & DE = 0 In Transmit Path When the CMS bit is `1' (i.e., in double clock mode) and the BOFF[2:0] bits are set, the start of the corresponding frame input on the TSDn/MTSD pin will delay `2 x N' clock cycles to the framing pulse on the TSFSn/MTSFS pin. (Here `N' is defined by the BOFF[2:0] bits.) When the CMS bit is `1' (i.e., in double clock mode) and the TSOFF[6:0] bits are set, the start of the corresponding frame input on the TSDn/ MTSD pin will delay `16 x M' clock cycles to the framing pulse on the TSFSn/MTSFS pin. (Here `M' is defined by the TSOFF[6:0].) The bit offset and channel offset are configured when the BOFF[2:0] bits and the TSOFF[6:0] bits are not `0' respectively. When the CMS bit is `0' and the BOFF[2:0] bits are set, the start of the corresponding frame input on the TSDn/MTSD pin will delay `N' clock cycles to the framing pulse on the TSFSn/MTSFS pin. (Here `N' is defined by the BOFF[2:0] bits.) When the CMS bit is `0' and the TSOFF[6:0] bits are set, the start of the corresponding frame input on the TSDn/MTSD pin will delay `8 x M' clock cycles to the framing pulse on the TSFSn/MTSFS pin. (Here `M' is defined by the TSOFF[6:0].) 77 August 20, 2009 IDT82P2282 DUAL T1/E1/J1 LONG HAUL / SHORT HAUL TRANSCEIVER In Non-multiplexed mode, the channel offset can be configured from 0 to 23 channels (0 & 23 are included). In Multiplexed mode, the channel offset can be configured from 0 to 127 channels (0 & 127 are included). 78 August 20, 2009 IDT82P2282 DUAL T1/E1/J1 LONG HAUL / SHORT HAUL TRANSCEIVER In the Transmit Clock Master mode, if TSCKn outputs pulses during the entire E1 frame, the Transmit System Interface is in Transmit Clock Master Full E1 mode. If only the clocks aligned to the selected timeslots are output on TSCKn, the Transmit System Interface is in Transmit Clock Master Fractional E1 mode. Table 43 summarizes how to set the transmit system interface of each link into various operating modes and the pins' direction of the transmit system interface in different operating modes. 3.18.2 E1 MODE In E1 mode, the Transmit System Interface can be set in Non-multiplexed Mode or Multiplexed Mode. In the Non-multiplexed Mode, the TSDn pin is used to input the data to each link at the bit rate of 2.048 Mb/s. While in the Multiplexed Mode, the data is byte interleaved from one high speed data stream and inputs on the MTSD pin at the bit rate of 8.192 Mb/s. In the Non-multiplexed mode, if the TSCK is from outside, the transmit system interface is in Transmit Clock Slave mode, otherwise if the device outputs clock to TSCK itself, the transmit system interface is in Transmit Clock Master mode.

When the G56K, GAP bits in TPLC indirect registers are set, the PCCE bit must be set to `1'. 3.18.2.1 Transmit Clock Master Mode In the Transmit Clock Master mode, each link uses its own timing signal on the TSCKn pin and framing pulse on the TSFSn pin to input the data on each TSDn pin. The signaling bits on the TSIGn pin are pertimeslot aligned with the data on the TSDn pin. In the Transmit Clock Master mode, the data on the system interface is clocked by the TSCKn. The active edge of the TSCKn used to update the pulse on the TSFSn is determined by the FE bit. The active edge of the TSCKn used to sample the data on the TSDn and TSIGn is determined by the DE bit. If the FE bit and the DE bit are not equal, the pulse on the TSFSn is ahead. In the Transmit Clock Master mode, the TSFSn can indicate the Basic frame, CRC Multi-frame and/or Signaling Multi-frame. The indications are selected by the FSTYP bit. The active polarity of the TSFSn is selected by the FSINV bit. The Transmit Clock Master mode includes two sub-modes: Transmit Clock Master Full E1 mode and Transmit Clock Master Fractional E1 mode. The TSCKn is gapped during the timeslots or the Bit 8 duration by selecting the G56K & GAP bits in the Transmit Payload Control. The data in the corresponding gapped duration is a don't care condition. 3.18.2.2 Transmit Clock Slave Mode In the Transmit Clock Slave mode, the timing signal on the TSCKn pin and the framing pulse on the TSFSn pin to input the data on the TSDn pin are provided by the system side. When the TSLVCK bit is set to `0', each link uses its own TSCKn and TSFSn; when the TSLVCK bit is set to `1' and both two links are in the Transmit Clock Slave mode, the two links use the TSCK[1] and TSFS[1] to input the data.

If the FE bit and the DE bit are not equal, the pulse on the TSFSn is ahead. The speed of the TSCKn can be selected by the CMS bit to be the same rate as the data rate on the system side (2.048 Mb/s) or double the data rate (4.096 Mb/s). If both two links use the TSCK[1] and TSFS[1] to input the data, the CMS bit of the two links should be set to the same value. If the speed of the TSCKn is double the data rate, there will be two active edges in one bit duration. In this case, the EDGE bit determines the active edge to sample the data on the TSDn and TSIGn pins. The pulse on the TSFSn pin is always sampled on its first active edge. In the Transmit Clock Slave mode, the TSFSn can indicate the Basic frame, CRC Multi-frame and/or Signaling Multi-frame. The indications are selected by the FSTYP bit. The active polarity of the TSFSn is 3.18.2.1.1 Transmit Clock Master Full E1 Mode Besides all the common functions described in the Transmit Clock Master mode, the special feature in this mode is that the TSCKn is a standard 2.048 MHz clock, and the data in all 32 timeslots in a standard E1 frame are clocked in by the TSCKn. 3.18.2.1.2 Transmit Clock Master Fractional E1 Mode Besides all the common functions described in the Transmit Clock Master mode, the special feature in this mode is that the TSCKn is a gapped 2.048 MHz clock (no clock signal during the selected timeslot). 79 August 20, 2009 IDT82P2282 DUAL T1/E1/J1 LONG HAUL / SHORT HAUL TRANSCEIVER selected by the FSINV bit. If the pulse on the TSFSn pin is not an integer multiple of 125 s, this detection will be indicated by the TCOFAI bit. If the TCOFAE bit is enabled, an interrupt will be reported by the INT pin when the TCOFAI bit is `1'. 3.18.2.3 Transmit Multiplexed Mode In the Transmit Multiplexed mode, one multiplexed bus is used to transmit the data to both two links. The data of Link 1 to Link 2 is byteinterleaved input from the multiplexed bus.

The signaling bits on the TSIGn/MTSIG pin are always per-timeslot aligned with the data on the TSDn/MTSD pin. Refer to Chapter 3.18.1.4 Offset for the base line without offset in different operating modes and the configuration of the offset. In Non-multiplexed mode, the timeslot offset can be configured from 0 to 31 timeslots (0 & 31 are included).

This function is only supported in T1/J1 mode ESF/SLC-96 format. - Enabled by the SIGSNAP bit, the signaling snapshot will be executed. The signaling snapshot means that the signaling bits of the first basic frame are locked and output as the signaling bits of the current whole multi-frame. This function is not supported in T1 DM format. - Enabled by the GSTRKEN bit, the signaling bits (ABCD) of all channels/timeslots of the corresponding link will be replaced by the signaling trunk conditioning code in the A,B,C,D bits. When the GSTRKEN bit is `0', the replacement can be performed on a per-channel/per-TS basis by setting the STRKEN bit in the corresponding channel/timeslot. The indirect registers of the Transmit Payload Control are accessed by specifying the address in the ADDRESS[6:0] bits. Whether the data is read from or written into the specified indirect register is determined by the RWN bit and the data is in the D[7:0] bits. The access status is indicated in the BUSY bit. Refer to Chapter 4.5 Indirect Register Access Scheme for details about the indirect registers write/read access. Different test patterns can be inserted in the data stream to be transmitted or the data stream to be transmitted can be extracted to the PRBS Generator/Detector for test in this block. To enable all the functions in the Transmit Payload Control, the PCCE bit must be set to `1'. The following methods can be executed on the data input from the TSDn/MTSD pins on a per-channel/per-TS basis or on a global basis of the corresponding link (the methods are arranged from the highest to the lowest in priority): - When the TESTEN bit is enabled and the PRBSDIR bit is `1', the data to be transmitted will be extracted to the PRBS Generator/Detector. The data to be transmitted can be extracted in unframed mode, in 8-bitbased mode or in 7-bit-based mode. This selection is made by the PRBSMODE[1:0] bits. In unframed mode, all the data stream to be transmitted is extracted and the per-channel/per-TS configuration in the TEST bit is ignored. In 8-bit-based mode or in 7-bit-based mode, the data will only be extracted on the channel/timeslot configured by the TEST bit. Refer to Chapter 3.27.1 PRBS Generator / Detector for details. - Configured by the ZCS[2:0] bits, four types of Zero Code Suppression can be selected to implement to the data of all the channels of the corresponding link. This function is only supported in T1/J1 mode. - Selected by the GSUBST[2:0] bits, the data of all channels/ timeslots of the corresponding link will be replaced by the trunk code set in the DTRK[7:0] bits, the milliwatt pattern defined in Table 36 and Table 37, or the payload loopback data from the Elastic Store Buffer (refer to Chapter 3.27.2.2 Payload Loopback). When the GSUBST[2:0] bits are set to `000', these replacements will be performed on a perchannel/per-TS basis by setting the SUBST[2:0] bits in the corresponding channel/timeslot. - Controlled by the SIGINS bit, the signaling bits input from the TSIGn/MTSIG pins (after processed by the signaling trunk conditioning replacement and/or valid signaling bits selection) can be inserted into its signaling bit position of the data stream to be transmitted. - Invert the most significant bit, the even bits and/or the odd bits by setting the SINV, OINV, EINV bits. - When the TESTEN bit is enabled and the PRBSDIR bit is `0', the data to be transmitted will be replaced by the test pattern generated from the PRBS Generator/Detector. The data to be transmitted can be replaced in unframed mode, in 8-bit-based mode or in 7-bit-based mode. This selection is made by the PRBSMODE[1:0] bits. In unframed mode, all the data stream to be transmitted is replaced and the perchannel/per-TS configuration in the TEST bit is ignored. In 8-bit-based mode or in 7-bit-based mode, the data will only be replaced on the channel/timeslot configured by the TEST bit. Refer to Chapter 3.27.1 PRBS Generator / Detector for details. The following methods can be executed on the signaling bits input from the TSIGn/MTSIG pins on a per-channel/per-TS basis or on a global basis of the corresponding link. The processed signaling bits will be inserted to the data stream to be transmitted if frame is generated.

The Yellow alarm signal will be manually inserted in the data stream to be transmitted when the XYEL bit is set, or the Yellow alarm signal will be inserted automatically by setting the AUTOYELLOW bit when Red alarm is declared in the received data stream. The Yellow alarm signal is transmitted in the DL bit position. Its pattern is `FF00' in T1 mode or `FFFF' in J1 mode. When the FDIS bit is `0', configured by the MIMICEN bit, the mimic pattern can be inserted into the bit right after each F-bit. The content of the mimic pattern is the same as the F-bit. The mimic pattern insertion is for diagnostic purpose. GENERATION 3.20.1.1 T1 / J1 Mode In T1/J1 mode, the data to be transmitted can be generated as Super-Frame (SF), Extended Super-Frame (ESF), T1 Digital Multiplexer (DM) or Switch Line Carrier - 96 (SLC-96) format. 3.20.1.1.1 Super Frame (SF) Format The SF is generated when the FDIS bit is `0'. The Frame Alignment Pattern (`100011011100' for T1 / `10001101110X' for J1) will replace the F-bit of each frame if the FDIS bit is set to `0'. The F-bit of the 12th frame in J1 mode should be `0' unless Yellow alarm signal is transmitted. When the FDIS bit is `0', one Ft bit (the F-bit in odd frame, refer to Table 12) will be inverted if the FtINV bit is set; one Fs bit (the F-bit in even frame, refer to Table 12) will be inverted if the FsINV bit is set. When the FDIS bit is `0', configured by the MIMICEN bit, the mimic pattern can be inserted into the bit right after each F-bit. The content of the mimic pattern is the same as the F-bit. The mimic pattern insertion is for diagnostic purpose. The Yellow alarm signal will be manually inserted in the data stream to be transmitted when the XYEL bit is set, or the Yellow alarm signal will be inserted automatically by setting the AUTOYELLOW bit when Red alarm is declared in the received data stream. The pattern and the position of the Yellow alarm is different in T1 and J1 modes: - In T1 mode, the Yellow alarm signal is logic 0 on the 2nd bit of each channel; - In J1 mode, the Yellow alarm signal is logic 1 on the 12th F-bit position. 3.20.1.1.3 T1 Digital Multiplexer (DM) Format (T1 only) The T1 DM is generated when the FDIS bit is `0'. The Frame Alignment Pattern (`100011011100') will replace the Fbit of each frame if the FDIS bit is set to `0'. When the FDIS bit is `0', one Ft bit (the F-bit in odd frame, refer to Table 14) will be inverted if the FtINV bit is set; one Fs bit (the F-bit in even frame, refer to Table 14) will be inverted if the FsINV bit is set. When the FDIS bit is `0', configured by the MIMICEN bit, the mimic pattern can be inserted into the bit right after each F-bit. The content of the mimic pattern is the same as the F-bit. The mimic pattern insertion is for diagnostic purpose. When the FDIS bit is `0', the DDS pattern (`0XX11101') will replace the Bit 8 & 5~1 of each Channel 24 (refer to Table 14). When the FDIS bit is `0', one 6-bit DDS pattern will be inverted if the DDSINV bit is set. The `D' bit in Bit 7 of each Channel 24 can be replaced with the HDLC data when the FDIS bit and the FDLBYP bit are both `0's. (Refer to Chapter 3.20.2 HDLC Transmitter for details). The Yellow alarm signal will be manually inserted in the data stream to be transmitted when the XYEL bit is set, or the Yellow alarm signal will be inserted automatically by setting the AUTOYELLOW bit when Red alarm is declared in the received data stream. The Yellow alarm signal is `0' transmitted in the `Y' bit in Bit 6 of each Channel 24. The `Y' bit should be `1' when there is no Yellow alarm signal to be transmitted. 3.20.1.1.2 Extended Super Frame (ESF) Format The ESF is generated when the FDIS bit is `0'. The Frame Alignment Pattern (`001011') will replace the F-bit in Frame (4n) (0 320 Severely Frame Alignment Bit Error event 1 Frame Alignment Bit Error event 1 Bipolar Violation (BPV) Error / HDB3 Code Violation (CV) Error event 1 Buffer Slip event 1 89 August 20, 2009 IDT82P2282 DUAL T1/E1/J1 LONG HAUL / SHORT HAUL TRANSCEIVER 3.20.6 ALL `ZERO'S & ALL `ONE'S After all the above processes, all 'One's or all `Zero's will overwrite all the data stream if the TAIS bit and the TXDIS bit are set.

The one-bit deletion or repetition occurs randomly. 07F, 17F 3.20.4 BIT-ORIENTED MESSAGE TRANSMITTER (T1/J1 ONLY) The Bit Oriented Message (BOM) can only be transmitted in the ESF format in T1/J1 mode. The BOM pattern is `111111110XXXXXX0' which occupies the DL of the F-bit in the ESF format. The six `X's represent the code that is programmed in the XBOC[5:0] bits. The BOM is transmitted only if the XBOC[5:0] bits are not all 'One's. 3.20.5 INBAND LOOPBACK CODE GENERATOR (T1/J1 ONLY) The Inband Loopback Code Generator can only transmit inband loopback code in a framed or unframed T1/J1 data stream. The length and the content of the inband loopback code are programmed in the CL[1:0] bits and the IBC[7:0] bits respectively. The code can only be transmitted when the IBCDEN bit is enabled. In framed mode, which is configured by the IBCDUNFM bit, the bits in all 24 channels are overwritten with the inband loopback code and the F-bit is not changed. In unframed mode, which is configured by the IBCDUNFM bit, all the bits in 24 channels and the F-bit are overwritten with the inband loopback code.

The function of timing option is also integrated in this block. The source of the transmit clock can be selected in the recovered clock from the line side, the processed clock from the backplane or the master clock generated by the clock generator. In Transmit Master mode, the Transmit Buffer is bypassed automatically. The source of the transmit clock can be selected between the recovered clock from the line side and the master clock generated by the internal clock generator (1.544 MHz in T1/J1 mode or 2.048 MHz in E1 mode). The selection is made by the XTS bit. In Transmit Clock Slave T1/J1 mode E1 rate, for the backplane timing is 2.048 MHz from backplane and the line timing is 1.544 MHz from the internal clock generator, the Transmit Buffer is selected automatically to absorb high frequency mapping jitter due to the E1 to T1/J1 mapping scheme. In this case, 1.544 MHz must be locked to 2.048 MHz by PLL of the internal clock generator. The XTS bit in the Transmit Timing Option register does not take effect. In other Transmit Clock Slave modes, whether the Transmit Buffer is bypassed and the source of the transmit clock selection are selected by the XTS bit. When the XTS bit is set to `1', line side timing is from internal clock generator, but backplane timing is from backplane, so the Transmit Buffer is selected to accommodate the different clocks. If these two clocks are not locked, an internal slip will occur in the Transmit Buffer. The source of the transmit clock is from the master clock generated by the internal clock generator (1.544 MHz in T1/J1 mode or 2.048 MHz in E1 mode). When the XTS bit is set to `0', the line side timing is also from the backplane timing, so the Transmit Buffer is bypassed. The source of the transmit clock is from the processed clock from the backplane. In Transmit Multiplexed mode, whether the Transmit Buffer is bypassed and the source of the transmit clock selection are the same as that described in other Transmit Clock Slave modes. In most applications of Transmit Clock Slave mode, the XTS bit can be set to `0' to bypass the Transmit Buffer (The Transmit Buffer is selected automatically in T1/J1 mode E1 rate). ENCODER 3.22.1 LINE CODE RULE 3.22.1.1 T1/J1 Mode In T1/J1 mode, the B8ZS line code rule or the AMI line code rule can be selected by the T_MD bit. 3.22.1.2 E1 Mode In E1 mode, the HDB3 line code rule or the AMI line code rule can be selected by the T_MD bit. 3.22.2 BPV ERROR INSERTION For test purpose, a BPV error can be inserted to the data stream to be transmitted by a transition from `0' to `1' on the BPV_INS bit. 3.22.3 ALL `ONE'S INSERTION When the LOS is detected in the receive path, all `One's will be inserted automatically to the data stream to be transmitted by setting the ATAO bit.

This selection is made by the TJA_E bit. The Jitter Attenuator consists of a FIFO and a DPLL, as shown in Figure 7. The FIFO is used as a pool to buffer the jittered input data, then the data is clocked out of the FIFO by a de-jittered clock. The depth of the FIFO can be 32 bits, 64 bits or 128 bits, as selected by the TJA_DP[1:0] bits. Accordingly, the constant delay produced by the Jitter Attenuator is 16 bits, 32 bits or 64 bits. The 128-bit FIFO is used when large jitter tolerance is expected, and the 32-bit FIFO is used in delay sensitive applications. The DPLL is used to generate a de-jittered clock to clock out the data stored in the FIFO. The DPLL can only attenuate the incoming jitter whose frequency is above Corner Frequency (CF). The jitter which frequency is lower than the CF passes through the DPLL without any attenuation. In T1/J1 applications, the CF of the DPLL can be 5 Hz or 1.26 Hz, as selected by the TJA_BW bit. In E1 applications, the CF of the DPLL can be 6.77 Hz or 0.87 Hz, as selected by the TJA_BW bit. The lower the CF is, the longer time is needed to achieve synchronization. If the incoming data moves faster than the outgoing data, the FIFO will overflow. If the incoming data moves slower than the outgoing data, the FIFO will underflow. The overflow or underflow is captured by the TJA_IS bit. When the TJA_IS bit is `1', an interrupt will be reported on the INT pin if enabled by the TJA_IE bit. To avoid overflowing or underflowing, the JA-Limit function can be enabled by setting the TJA_LIMT bit. When the JA-Limit function is enabled, the speed of the outgoing data will be adjusted automatically if the FIFO is close to its full or emptiness. The criteria of speed adjustment start are listed in Table 6. Though the LA-Limit function can reduce the possibility of FIFO overflow and underflow, the quality of jitter attenuation is deteriorated. Selected by the TJITT_TEST bit, the real time interval between the read and write pointer of the FIFO or the peak-peak interval between the read and write pointer of the FIFO can be indicated in the TJITT[6:0] bits. When the TJITT_TEST bit is `0', the current interval between the read and write pointer of the FIFO will be written into the TJITT[6:0] bits. When the TJITT_TEST bit is `1', the current interval is compared with the old one in the TJITT[6:0] bits and the larger one will be indicated by the TJITT[6:0] bits. The performance of Receive Jitter Attenuator meets the ITUT I.431, G.703, G.736 - 739, G.823, G.824, ETSI 300011, ETSI TBR 12/ 13, AT&T TR62411, TR43802, TR-TSY 009, TR-TSY 253, TR-TRY 499 standards.

The values are listed in Table 62 to Table 73. Do the followings step by step, the desired waveform can be programmed based on the selected waveform template: 1. Select the UI by the UI[1:0] bits; 2. Specify the sample address in the selected UI by the SAMP[3:0] bits; 3. Write sample data to the WDAT[6:0] bits. It contains the data to be stored in the RAM, addressed by the selected UI and the corresponding sample address; 4. Set the RW bit to `0' to write data to RAM, or to `1' to read data from RAM; 5. Set the DONE bit to implement the read or write operation; (Repeat the above steps until all the sample data are written to or read from the internal RAM). 6. Write the scaling data to the SCAL[5:0] bits to scale the amplitude of the waveform based on the selected standard pulse amplitude. Table 62 to Table 73 give all the sample data based on preset pulse templates and LBOs in details for reference. For preset pulse templates and LBOs, scaling up/down against the pulse amplitude is not supported. 1. Table 62 - Transmit Waveform Value For E1 75 2. Table 63 - Transmit Waveform Value For E1 120 3.

Table 73 - Transmit Waveform Value For DS1 -22.5 dB LBO To meet the template, two preset waveform templates are provided corresponding to two kinds of cable impedance. The selection is made by the PULS[3:0] bits. In internal impedance matching mode, if the cable impedance is 75 , the PULS[3:0] bits should be set to `0000'; if the cable impedance is 120 , the PULS[3:0] bits should be set to `0001'. In external impedance matching mode, for both 75 and 120 cable impedance, the PULS[3:0] bits should be set to `0001'. 3.24.2 LINE BUILD OUT (LBO) (T1 ONLY) In long haul applications, the output on the TTIPn/TRINGn pins should be attenuated before transmission to prevent the cross-talk in the far end. Three LBOs are used to implement the pulse attenuation. Four grades of attenuation with each step of 7.5 dB are specified in the FCC Part 68 Regulations. The attenuation grade is selected by the PULS[3:0] bits. The details are listed in Table 61. Table 61: LBO PULS[3:0] Setting In T1 Mode Cable Configuration PULS[3:0] 0 dB LBO -7.5 dB LBO -15.0 dB LBO -22.5 dB LBO 0010 1001 1010 1011 3.24.3 USER-PROGRAMMABLE ARBITRARY WAVEFORM User-programmable arbitrary waveform can be used in both short haul applications and long haul applications if the PULS[3:0] bits are set to `11XX' in the corresponding link. This allows the transmitter performance to be tuned for a wide variety of line condition or special application. Each pulse shape can extend up to 4 UIs (Unit Interval) addressed by the UI[1:0] bits, and each UI is divided into 16 sub-phases addressed by the SAMP[3:0] bits. The pulse amplitude of each phase is represented by a binary byte, within the range from +63 to -63, stored in the WDAT[6:0] bits in signed magnitude form. The maximum number +63 (D) represents the positive maximum amplitude of the transmit pulse while the most negative number -63 (D) represents the maximum negative amplitude of the transmit pulse. Thus, up to 64 bytes are used. For each channel, a 64 bytes RAM is available. There are twelve standard templates which are stored in a local ROM. One of them can be selected as reference and made some changes to get the desired waveform. To do this, the first step is to choose a set of waveform value, which is the most similar to the desired pulse shape, from the following 12 tables (Table 62 to Table 73), and set the SCAL[5:0] bits to the corresponding standard value. Table 62 to Table 73 list the sample data and the standard scaling value of each of the 12 templates. Modifying the corresponding sample data can get the desired transmit pulse shape. By increasing or decreasing by `1' from the standard value in the SCAL[5:0] bits, the pulse amplitude can be scaled up or down at the percentage ratio against the standard pulse amplitude if necessary.

One step change of this value results in 25% scaling up/down against the pulse amplitude. When more than one UI are used to compose the pulse template and the pulse amplitude is not set properly, the overlap of two consecutive pulses will make the pulse amplitude overflow (exceed the maximum limitation). This overflow is captured by the DAC_IS bit, and if enabled by the DAC_IE bit, an interrupt will be reported by the INT pin.

The following ways will set the drivers to High-Z: 1. Setting the THZ pin to high will globally set both the Line Drivers to High-Z; 2. When there is no clock input on the OSCI pin, both the Line Drivers will be High-Z (no clock means this: the input on the OSCI pin is in high/low level, or the duty cycle is less than 30% or larger than 70%); 3. After software reset, hardware reset or power on, both the Line Drivers will be High-Z; 4. Setting the T_HZ bit to `1' will set the corresponding Line Driver to High-Z; 5. In Transmit Clock Master mode, if the XTS bit is `1', the source of the transmit clock is from the recovered clock from the line side. When the recovered clock from the line side is lost, the Line Driver in the corresponding link will be High-Z; 6. In Transmit Clock Slave mode, if the XTS bit is `0', the source of the transmit clock is from the backplane timing clock. When the backplane timing clock is lost (i.e., no transition for more than 72 T1/E1/J1 cycles), the Line Driver in the corresponding link will be High-Z. However, there is an exception in this case. That is, if the link is in Remote Loopback mode, the Line Driver will not be High-Z. 7. When the transmit path is power down, the Line Driver in the corresponding link will be High-Z. By these ways, the TTIPn and TRINGn pins will enter into high impedance state immediately. Controlled by the DFM_ON bit, the output driver short-circuit protection can be enabled. The driver's output current (peak to peak) is limited to 110 mA typically. When the output current exceeds the limitation, the transmit driver failure will be captured by the DF_S bit. Selected by the DF_IES bit, a transition from `0' to `1' on the DF_S bit or any transition from `0' to `1' or from `1' to `0' on the DF_S bit will set the DF_IS bit. When the DF_IS bit is `1', an interrupt on the INT pin will be reported if enabled by the DF_IE bit. 101 August 20, 2009 IDT82P2282 3.26 DUAL T1/E1/J1 LONG HAUL / SHORT HAUL TRANSCEIVER TRANSMITTER IMPEDANCE MATCHING In T1/J1 mode, the transmitter impedance matching can be realized by using internal impedance matching circuit. 100 , 110 , 75 or 120 internal impedance matching circuit can be selected by the T_TERM[1:0] bits. The external impedance circuitry is not supported in T1/J1 mode. In E1 mode, the transmitter impedance matching can be realized by using internal impedance matching circuit or external impedance matching circuit. When the T_TERM[2] bit is `0', the internal impedance matching circuit is enabled. 100 , 110 , 75 or 120 internal impedance matching circuit can be selected by the T_TERM[1:0] bits. When the T_TERM[2] bit is `1', the internal impedance matching circuit is disabled, and different external resistors should be used to realize different impedance matching. Figure 2 shows the appropriate components to connect with the cable for one link. Table 75 lists the recommended impedance matching values for the transmitter.

Before the insertion, the generated pattern can be inverted when the TINV bit is set. 3.27.1 PRBS GENERATOR / DETECTOR The PRBS Generator / Detector generates test pattern to either the transmit or receive direction, and detects the pattern in the opposite direction. The direction is determined by the PRBSDIR bit. The pattern can be generated or detected in unframed mode, in 8-bit-based mode or in 7-bit-based mode. This selection is made by the PRBSMODE[1:0] bits. In unframed mode, all the data streams are extracted or replaced and the per-channel/per-TS configuration in the TEST bit is ignored. In 8-bit-based mode or in 7-bit-based mode, the extracted or replaced channel/timeslot is specified by the TEST bit. (In 7-bit-based mode, only the higher 7 bits of the selected channel/timeslot are used for PRBS test). 3.27.1.2 Pattern Detector When there is a transition from `0' to `1' on the TESTEN bit, the pattern detector starts to extract the data. The extracted data is used to regenerate a desired pattern which is selected by the PATS[1:0] bits. The extracted data is compared with the re-generated pattern. If the extracted data coincides with the pattern, the pattern is synchronized and it will be indicated by the SYNCV bit. In synchronization state, each mismatched bit will generate a PRGD Bit Error event. This event is captured by the BERI bit and is forwarded to the Performance Monitor. An interrupt reported on the INT pin will be enabled by the BERE bit if the BERI bit is `1'. When there are more than 10-bit errors detected in the fixed 48-bit window, the extracted data is out of synchronization and it also will be indicated by the SYNCV bit. Any transition (from `1' to `0' or from `0' to `1') on the SYNCV bit will set the SYNCI bit. An interrupt reported on the INT pin will be enabled by the SYNCE bit if the SYNCI bit is `1'. Before the data extracted to the pattern detector, the data can be inverted by setting the RINV bit. 3.27.1.1 Pattern Generator Three patterns are generated: 211-1 pattern per O.150, 215-1 pattern per O.152 and 220-1 pattern per O.150-4.5. They are selected by the PATS[1:0] bits. The selected pattern is generated once there is a transition from `0' to `1' on the TESTEN bit.

The received data output from the Elastic Store Buffer is internally looped to the Transmit Payload Control. In Payload Loopback mode, the received data is still output to the system side, while the data to be transmitted from the system side is replaced by the Payload Loopback data. 3.27.2 LOOPBACK System Loopback, Payload Loopback, Local Digital Loopback 1 & 2, Remote Loopback and Analog Loopback are all supported in the IDT82P2282. Their routes are shown in the Functional Block Diagram. 3.27.2.1 System Loopback The System Loopback can only be implemented when the Receive System Interface and the Transmit System Interface are in different Non-multiplexed operating modes (one in Clock Master mode and the other in Clock Slave mode). However, in T1/J1 mode, when either the receive path or the transmit path is in T1/J1 mode E1 rate, the System Loopback is not supported. Distinguished by the loopback direction, the System Loopback can be divided into System Remote Loopback and System Local Loopback. When the data and signaling bits from the transmit path are looped to the receive path, it is System Remote Loopback. When the data and signaling bits from the receive path are looped to the transmit path, it is System Local Loopback. 3.27.2.3 Local Digital Loopback 1 Enabled by the DLLP bit, the Local Digital Loopback 1 is implemented. The data stream output from the Transmit Buffer is internally looped to the Frame Processor. In Local Digital Loopback 1 mode, the data stream to be transmitted is still output to the line side, while the data stream received from the line side is replaced by the Local Digital Loopback 1 data. 3.27.2.4 Remote Loopback Enabled by the RLP bit, the Remote Loopback is implemented. The data stream output from the optional Receive Jitter Attenuator is internally looped to the optional Transmit Jitter Attenuator. In Remote Loopback mode, the data stream received from the line side is still output to the system, while the data stream to be transmitted is replaced by the Remote Loopback data. 3.27.2.1.1 System Remote Loopback Enabled by the SRLP bit, the System Remote Loopback is implemented. The data and signaling bits to be transmitted on the TSDn and TSIGn pins are internally looped to the RSDn and RSIGn pins. When the receive path is in Receive Clock Master mode and the transmit path is in Transmit Clock Slave mode, the clock signal and the framing pulse from the system side on the TSCKn and TSFSn pins are looped to the RSCKn and RSFSn pins respectively. When the transmit path is in Transmit Clock Master mode and the receive path is in Receive Clock Slave mode, the clock signal and the framing pulse from the system side on the RSCKn and RSFSn pins are looped to the TSCKn and TSFSn pins respectively. In System Remote Loopback mode, the data stream to be transmitted is still output to the line side, while the data stream received from the line side is replaced by the System Remote Loopback data. 3.27.2.5 Local Digital Loopback 2 Enabled by the DLP bit, the Local Digital Loopback 2 is implemented. The data stream output from the optional Transmit Jitter Attenuator is internally looped to the Optional Receive Jitter Attenuator. In Local Digital Loopback 2 mode, the data stream to be transmitted is still output to the line side, while the data stream received from the line side is replaced by the Local Digital Loopback 2 data. 3.27.2.6 Analog Loopback Enabled by the ALP bit, the Analog Loopback is implemented. The data stream to be transmitted on the TTIPn/TRINGn pins is internally looped to the RTIPn/RRINGn pins. In Analog Loopback mode, the data stream to be transmitted is still output to the line side, while the data stream received from the line side is replaced by the Analog Loopback data. If analog loopback is enabled, line driver should be set to normal (T_HZ=0 & THZ pin is tied to ground). 3.27.2.1.2 System Local Loopback Enabled by the SLLP bit, the System Local Loopback is implemented. The received data and signaling bits to be output on the RSDn and RSIGn pins are internally looped to the TSDn and TSIGn pins. When the receive path is in Receive Clock Master mode and the transmit path is in Transmit Clock Slave mode, the recovered clock signal and framing pulse on the RSCKn and RSFSn pins are looped to the TSCKn and TSFSn pins respectively. When the transmit path is in Transmit Clock Master mode and the receive path is in Receive Clock Slave mode, the TSCKn and TSFSn pins are looped to the RSCKn and RSFSn pins respectively. In System Local Loopback mode, the data stream received from the line side is still output to the system through the RSDn and RSIGn pins, while the data stream to be transmitted through the TSDn and TSIGn pins are replaced by the System Local Loopback data. 3.27.3 G.772 NON-INTRUSIVE MONITORING When the G.772 Non-Intrusive Monitoring is implemented, only the Link 2 is in normal operation and the Link 1 is configured to monitor the receive path or transmit path of Link 2. Whether the G.772 Non-Intrusive Monitoring is implemented and which direction (receive/transmit) and link is monitored are both determined by the MON[3] and MON[0] bits. The G.772 Non-Intrusive Monitoring meets the ITU-T G.772. It is shown in Figure 36. The data stream of Link 1 is received from Link 2, then processed as normal. The operation of the monitored link is not effected. 104 August 20, 2009 IDT82P2282 DUAL T1/E1/J1 LONG HAUL / SHORT HAUL TRANSCEIVER Link 1 TSD1 / MTSD TTIP1 TSIG1 / MTSIG TSFS1 / MTSFS Transmit System Interface Transmit Internal Termination TRING1 TSCK1 / MTSCK RSCK1 / MRSCK RTIP1 RSFS1 / MRSFS RSIG1 / MRSIG Receive System Interface Receive Internal Termination RRING1 RSD1 / MRSD G.772 NonIntrusive Monitor Link 2 TSD2 TTIP2 TSIG2 TSFS2 Transmit System Interface Transmit Internal Termination TRING2 TSCK2 RSCK2 RTIP2 RSFS2 RSIG2 Receive System Interface Receive Internal Termination RRING2 RSD2 Figure 36.

Then the source is served after it is found. After reading the Interrupt Requisition Link ID register, the Interrupt Module Indication registers of the interrupting link are read. The Interrupt Module Indication bits will be `1' if there are interrupts in the corresponding function block. To find the eventual interrupt sources, the Interrupt Indication and Status bits in the block are polled if their Interrupt Enable bits are enabled. Then the sources are served after they are found. When the INT pin is asserted low, it means at least one interrupt has occurred in the device. Reading the Timer Interrupt Indication register and Interrupt Requisition Link ID register will find whether the timer interrupt occurs or in which link the interrupt occurs.

Apply ground; 2. Apply 3.3 V; 3. Apply 1.8 V. 4.2 RESET 2ms Microprocessor Interface RESET When the device is powered-up, all the registers contain random values. The hardware reset pin RESET must be asserted low during the power-up and the low signal should last at least 10 ms to initialize the device. After the RESET pin is asserted high, all the registers are in their default values and can be accessed after 2 ms (refer to Figure 37). During normal operation, the device can be reset by hardware or software anytime. When it is hardware reset, the RESET pin should be asserted low for at least 100 ns. Then all the registers are in their default values and can be accessed after 2 ms (refer to Figure 38). When it is software reset, a write signal to the Software Reset register will reset all the registers except the T1/J1 Or E1 Mode register to their default values. Then the registers are accessible after 2 ms. However, the T1/J1 Or E1 Mode register can not be reset by the software reset. It can only be reset by the hardware reset. Hardware or software reset can only be applied when the clock on the OSCI pin is available. It should be mentioned that when the setting in the T1/J1 Or E1 Mode register is changed, a software reset must be applied. Vdd access Figure 38. Hardware Reset In Normal Operation 4.3 RECEIVE / TRANSMIT PATH POWER DOWN The receive path of any of the two links can be power down by setting the R_OFF bit. During the receive path power down, the output of the corresponding path is low. The transmit path of any of the two links can be set to power down by the T_OFF bit. During the transmit path power down, the output of the corresponding path is High-Z. 10ms RESET 2ms Microprocessor Interface access Figure 37.

In this mode, only the CS, SCLK, SDI and SDO pins are interfaced with the microprocessor. A falling transition on CS pin indicates the start of a read/write operation, and a rising transition indicates the end of the operation. After the CS pin is set to low, two bytes include instruction and address bytes on the SDI pin is input to the device on the rising edge of the SCLK pin. First byte consists of one instruction bit at MSB and three address bits at LSB, the second byte is low 8 address bits. If the MSB is `1', it is read operation. If the MSB is `0', it is write operation. If the device is in read operation, the data read from the specified register is output on the SDO pin on the falling edge of the SCLK (refer to Figure 39). If the device is in write operation, the data written to the specified register is input on the SDI pin following the address byte (refer to Figure 40). The microprocessor interface provides access to read and write the registers in the device. The interface consists of Serial Peripheral Interface (SPI) and parallel microprocessor interface.

Before setting any other registers, the operating mode should be selected in registers 020H and 120H. According to the access method, the registers can be divided into direct registers and indirect registers. In the direct registers, the registers can be divided into global configuration registers and per-link configuration registers. The register with only one address following its name is the global configuration register, and the register with a set of address (two addresses) following its name is the per-link configuration register.

JTAG Architecture IEEE STD 1149.1 JTAG Test Access Port 357 August 20, 2009 IDT82P2282 DUAL T1/E1/J1 LONG HAUL / SHORT HAUL TRANSCEIVER 6.1 JTAG INSTRUCTIONS AND INSTRUCTION REGISTER (IR) The instructions are shifted in LSB first to this 3-bit register. See Table 82 for details of the codes and the instructions related. The IR (Instruction Register) with instruction decode block is used to select the test to be executed or the data register to be accessed or both. Table 82: IR Code IR Code Instruction Comment 000 EXTEST 010 SAMPLE / PRELOAD 001 IDCODE 111 BYPASS 011 CLAMP 010 HIGHZ 101 - The external test instruction allows testing of the interconnection to other devices. When the current instruction is the EXTEST instruction, the boundary scan register is placed between TDI and TDO. The signal on the input pins can be sampled by loading the boundary scan register using the Capture-DR state. The sampled values can then be viewed by shifting the boundary scan register using the Shift-DR state. The signal on the output pins can be controlled by loading patterns shifted in through input TDI into the boundary scan register using the Update-DR state. The sample/preload instruction is used to allow scanning of the boundary-scan register without causing interference to the normal operation of the on-chip system logic. Data received at system input pins is supplied without modification to the on-chip system logic; data from the on-chip system logic is driven without modification through the system output pins. SAMPLE allows a snapshot to be taken of the data flowing from the system pins to the on-chip system logic or vice versa, without interfering with the normal operation of the assembled board. PRELOAD allows an initial data pattern to be placed at the latched parallel outputs of boundary-scan register cells prior to selection of another boundary-scan test operation. The identification instruction is used to connect the identification register between TDI and TDO. The device's identification code can then be shifted out using the Shift-DR state. The BYPASS instruction shifts data from input TDI to output TDO with one TCK clock period delay. The instruction is used to bypass the device. This instruction allows the state of the signals driven from device pins to be determined from the boundary-scan register while the bypass register is selected as the serial path between TDI and TDO. The signals driven from the device pins will not change while the CLAMP instruction is selected. Use of the HIGHZ instruction places the device in a state in which all of its system logic outputs are placed in an inactive drive state (e.g., high impedance). In this state, and in-circuit test system may drive signals onto the connections normally driven by a device output without incurring the risk of damage to the device.

The value shown next to each state transition in this figure states the value present at TMS at each rising edge of TCK. The TAP controller is a 16-state synchronous state machine. Figure - 42 shows its state diagram. A description of each state is listed in Table 85. Note that the figure contains two main branches to access Table 85: TAP Controller State Description State Description Test Logic In this state, the test logic is disabled to continue normal operation of the device. During initialization, the device initializes the instruction register with the Reset IDCODE instruction. Regardless of the original state of the controller, the controller enters the Test-Logic-Reset state when the TMS input is held high for at least 5 rising edges of TCK. The controller remains in this state while TMS is high. Run-Test/ This is a controller state between scan operations. Once in this state, the controller remains in the state as long as TMS is held low. The instruction regIdle ister and all test data registers retain their previous state. When TMS is high and a rising edge is applied to TCK, the controller moves to the Select-DR state. Select-DR- This is a temporary controller state and the instruction does not change in this state. The test data register selected by the current instruction retains its Scan previous state. If TMS is held low and a rising edge is applied to TCK when in this state, the controller moves into the Capture-DR state and a scan sequence for the selected test data register is initiated. If TMS is held high and a rising edge applied to TCK, the controller moves to the Select-IR-Scan state. Capture- In this state, the Boundary Scan Register captures input pin data if the current instruction is EXTEST or SAMPLE/PRELOAD. The instruction does not DR change in this state. The other test data registers, which do not have parallel input, are not changed. When the TAP controller is in this state and a rising edge is applied to TCK, the controller enters the Exit1-DR state if TMS is high or the Shift-DR state if TMS is low. Shift-DR In this controller state, the test data register connected between TDI and TDO as a result of the current instruction shifts data on stage toward its serial output on each rising edge of TCK. The instruction does not change in this state. When the TAP controller is in this state and a rising edge is applied to TCK, the controller enters the Exit1-DR state if TMS is high or remains in the Shift-DR state if TMS is low. Exit1-DR This is a temporary state. While in this state, if TMS is held high, a rising edge applied to TCK causes the controller to enter the Update-DR state, which terminates the scanning process. If TMS is held low and a rising edge is applied to TCK, the controller enters the Pause-DR state. The test data register selected by the current instruction retains its previous value and the instruction does not change during this state. Pause-DR The pause state allows the test controller to temporarily halt the shifting of data through the test data register in the serial path between TDI and TDO. For example, this state could be used to allow the tester to reload its pin memory from disk during application of a long test sequence. The test data register selected by the current instruction retains its previous value and the instruction does not change during this state. The controller remains in this state as long as TMS is low. When TMS goes high and a rising edge is applied to TCK, the controller moves to the Exit2-DR state. Exit2-DR This is a temporary state. While in this state, if TMS is held high, a rising edge applied to TCK causes the controller to enter the Update-DR state, which terminates the scanning process. If TMS is held low and a rising edge is applied to TCK, the controller enters the Shift-DR state. The test data register selected by the current instruction retains its previous value and the instruction does not change during this state. Update-DR The Boundary Scan Register is provided with a latched parallel output to prevent changes while data is shifted in response to the EXTEST and SAMPLE/PRELOAD instructions. When the TAP controller is in this state and the Boundary Scan Register is selected, data is latched into the parallel output of this register from the shift-register path on the falling edge of TCK. The data held at the latched parallel output changes only in this state. All shift-register stages in the test data register selected by the current instruction retain their previous value and the instruction does not change during this state. Select-IR- This is a temporary controller state. The test data register selected by the current instruction retains its previous state. If TMS is held low and a rising Scan edge is applied to TCK when in this state, the controller moves into the Capture-IR state, and a scan sequence for the instruction register is initiated. If TMS is held high and a rising edge is applied to TCK, the controller moves to the Test-Logic-Reset state. The instruction does not change during this state. Capture-IR In this controller state, the shift register contained in the instruction register loads a fixed value of '100' on the rising edge of TCK. This supports fault-isolation of the board-level serial test data path. Data registers selected by the current instruction retain their value and the instruction does not change during this state. When the controller is in this state and a rising edge is applied to TCK, the controller enters the Exit1-IR state if TMS is held high, or the Shift-IR state if TMS is held low. Shift-IR In this state, the shift register contained in the instruction register is connected between TDI and TDO and shifts data one stage towards its serial output on each rising edge of TCK. The test data register selected by the current instruction retains its previous value and the instruction does not change during this state. When the controller is in this state and a rising edge is applied to TCK, the controller enters the Exit1-IR state if TMS is held high, or remains in the Shift-IR state if TMS is held low. Exit1-IR This is a temporary state. While in this state, if TMS is held high, a rising edge applied to TCK causes the controller to enter the Update-IR state, which terminates the scanning process. If TMS is held low and a rising edge is applied to TCK, the controller enters the Pause-IR state. The test data register selected by the current instruction retains its previous value and the instruction does not change during this state.

The test data register selected by the current instruction retains its previous value and the instruction does not change during this state. The controller remains in this state as long as TMS is low. When TMS goes high and a rising edge is applied to TCK, the controller moves to the Exit2-IR state. Exit2-IR This is a temporary state. While in this state, if TMS is held high, a rising edge applied to TCK causes the controller to enter the Update-IR state, which terminates the scanning process. If TMS is held low and a rising edge is applied to TCK, the controller enters the Shift-IR state. The test data register selected by the current instruction retains its previous value and the instruction does not change during this state. Update-IR The instruction shifted into the instruction register is latched into the parallel output from the shift-register path on the falling edge of TCK. When the new instruction has been latched, it becomes the current instruction. The test data registers selected by the current instruction retain their previous value.
