PRELIMINARY XRT86SH328 28-CHANNEL DS1/E1 FRAMER/LIU WITH DS3 MUX & VT-MAPPER - SONET JANUARY 2007 GENERAL DESCRIPTION The XRT86SH328 is an integrated VT/TU Mapper with 28 port T1/E1 Line Interface Units. The XRT86SH328 contains integrated DS1/E1/J1 Framers for performance monitoring. The XRT86SH328 processes the Section, Line and Path overhead in the SONET/SDH data-stream. The processing of path overhead bytes within the STS-1s or TUG-3s include 64 bytes (of buffer) for storing the (Section Trace and Path Trace) messages. Path Overhead bytes can be accessed either by on-chip registers or a Serial Output Port. Each of the 28 T1 or E1 Channels use an internal DeSynchronizer circuit with an internal pointer leak algorithm. This removes the jitter due to mapping and pointer adjustments from the T1 or E1 signals that are de-mapped from the incoming SONET/SDH datastream. These De-Synchronizer circuits do not need any external clock references for its operation. The Transmit Blocks permit flexible insertion of TOH and POH bytes via both Hardware and Software control. The Receive Blocks receive a SONET STS-1 signals or an SDH STM-1 signal and performs the necessary Transport and Path Overhead Processing. A PRBS Pattern Generator and Receiver is implemented within each of the 28 T1/E1 channels in order to implement and measure Bit-Error performance. A general purpose Microprocessor Interface is included for control, configuration and monitoring.

In the Transmit (Drop) DirectionThe STS-1/STS-3 Telecom Bus to compute either the EVEN or ODD parity over the contents of the (1) TxD_D[7:0] output pins, or (2) TxD_D[7:0] output pins, the states of the TxD_PL and TxD_C1J1 output pins (depending upon user setting for BIT 3). b. In the Receive (Add) DirectionReceive STS-1/STS-3 Telecom Bus to compute and verify the EVEN or ODD parity over the contents of the (1) RxA_D[7:0] input pins, or (2) RxA_D[7:0] input pins, the states of the RxA_PL and RxA_C1J1 input pins (depending upon user setting for BIT 3). 0 - Configures Transmit (Drop) Telecom Bus to compute EVEN parity and configures the Receive (Add) Telecom Bus to verify EVEN parity. 1 - Configures Transmit (Drop) Telecom Bus to compute ODD parity and configures the Receive (Add) Telecom Bus to verify ODD parity. BIT 1 - Telecom Bus Parity Enable This READ/WRITE bit-field is used to either enable or disable parity calculation and placement via the TxA_DP output pin. This bit field also is used to enable or disable parity verification by the Receive Telecom Bus. 0 - Disables Parity Calculation (on the Transmit Telecom Bus) and Disables Parity Verification (on the Receive Telecom Bus. 1 - Enables Parity Calculation and Verification BIT 0 - Telecom Bus - Rephase Enable This READ/WRITE bit-field is used to configure the Receive STS-1/STS-3 Telecom Bus to operate in either the Rephase ON or Rephase OFF Modes. If the user configures the Receive STS-1/STS-3 Telecom Bus Interface to operate on the Rephase ON Mode, then the Receive STS-1/STS-3/STS-1/STS-3 TOH/POH Processor blocks will internally compute the Pointer Bytes, based upon the data that it receives via the RxD_D[7:0] input pins. If the user configures the Receive STS-1/STS-3 Telecom Bus Interface to operate in the Rephase OFF Mode, then the Receive STS-1/STS-3/STS-1/STS-3 TOH/POH Processor blocks will NOT internally compute the Pointer Bytes, based upon the data that it receives via the RxD_D[7:0] input pins. In this case, the Voyager device will rely upon the signaling via the Telecom Bus Interface pins (e.g., via the RxD_PL and RxD_C1J1V1_FP pins) in order to compute these pointer bytes. NOTE: If the Receive STS-1/STS-3 Telecom Bus is being provided with pulses denoting the C1 and J1 bytes (via the RxD_C1J1V1_FP input pin), then this feature is unnecessary. 0 - Configures the Telecom Bus Interface to operate in the Rephase OFF Mode. 1 - Configures the Telecom Bus Interface to operate in the Rephase ON Mode. 58 PRELIMINARY REV.

Hence, the XRT86SH328 device contains a total of 56 Transmit/Receive DS1/E1 Framer blocks. Therefore, in Table _-1, the value of N can range in value from 0x01 to 0x38. OBVIOUS QUESTION: What value of N pertains to which of the 56 T1/E1 Framer blocks within the chip? The answer to this question depends upon whether the XRT86SH328 has been configured to operate in the VT-Mapper (with T1/E1 Framing) or in the M13 MUX (with T1/E1 Framing) Mode. Table 393 and Table 394 present the values for N (for each T1/E1 Framer block) as a function of Channel Number and Signal Direction for VT- Mapper (with T1/E1 Framing) and M13 MUX (with T1/E1 Framing) applications, respectively. Further, Figure 18 (which depicts an illustration of the various T1/E1 Framer blocks within a given channel) can be used as a point of reference when looking at Table 393 and Table 394. 260 PRELIMINARY XRT86SH328 28-CHANNEL DS1/E1 FRAMER/LIU WITH DS3 MUX & VT-MAPPER - SONET APPLICATIONS REV.

BIT [3:2] - CRC Multi Frame Alignment Declaration Criteria Select[1:0]: These bits allow the user to select which CRC Multi Frame Alignment declaration criteria the receive E1 framer block will employ. The receive E1 framer block will check for CRC Multi Frame Alignmnet by checking the incoming E1 data stream and determining whether the international bits (bit 1 of time slot 0) of non-FAS frames match the CRC multi frame alignment pattern (0,0,1,0,1,1,E1,E2). CAS MF Align Sel CAS MF ALIGN SEL[1:0] CAS MULTI FRAME ALIGNMENT DECLARATION ALGORITHM CRITERIA 00 CRC Multi Frame Alignment Disabled. 01 CRC Multi Frame Alignment is enabled. Alignment is declared if at least 1 valid CRC multi frame alignment signal is observed within 8 msec. 10 CRC Multi Frame Alignment is enabled. Alignment is declared if at least 2 valid CRC multi frame alignment signals are observed within 8 msec. 11 CRC Multi Frame Alignment is enabled. Alignment is declared if at least 3 valid CRC multi frame alignment signals are observed within 8 msec. NOTE: For information on the criteria that the receive E1 framer block uses to declare the Loss of CRC Multi Frame Alignment defect condition, please see the register description for the Framing Control Register 0xN10Bh. BIT 1 - Additional Frame Check Enable - FAS Frame Alignment Declaration: This bit is used to configure the receive E1 framer block to perform some additional FAS frame synchronization checking prior to declaration FAS frame alignment. If the user implements this feature, then the receive E1 framer block will perform some more testing on two additional E1 frames, prior to declaring the FAS frame Alignment condition. 0 = Disabled. 1 = Enables additional FAS frame checking. BIT 0 - FAS Alignment Declaration Algorithm Select: This bit specifies which algorithm the receive E1 framer block uses in its search for the FAS alignment. 0 = FAS Alignment Algorithm 1 1 = FAS Alignment Algorithm 2 FAS Alignment Algorithm 1 Desciption a. Step 1: The receive E1 Framer block begins by searching for the correct 7-bit FAS pattern. Go to step 2 if found. b. Step 2: Check if the FAS is absent in the following frame by verifying that bit 2 of the assumed time slot 0 of the Non-FAS frame is a one. Go back to step 1 if failed, otherwise go to step 3. c. Step 3: check if the FAS is present in the assumed time slot 0 of the third frame. Go back to step 1 if failed. After the first three steps (if all passed), the receive E1 framer block will declare FAS in Sync if Frame Check Sequence (BIT 1 of this register) is disabled. If frame check sequence is enabled, then the receive E1 framer block will need to verify the correct frame alignment. FAS Alignment Algorithm 2 Description Algorithm 2 is similar to algorithm 1 but adds a one-frame hold off time after the second step fails. After the second step fails, it waits for the next assumed FAS in the next frame before it begins the new search for the correct FAS pattern. 297 PRELIMINARY XRT86SH328 28-CHANNEL DS1/E1 FRAMER/LIU WITH DS3 MUX & VT-MAPPER - SONET APPLICATIONS REV.

Conversely, if the user opts to use the "Extended" RDI-V, then the RDI-V indicator will be transported via both Bit 8 (RDI-V) within the V5 byte, and Bits 5, 6 and 7 within the Z7/K4 byte. 0 - Configures the VT Mapper block to use the SRDI-V form of signaling. 1 - Configures the VT-Mapper block to use the ERDI-V form of signaling. NOTE: This configuration setting only applies to the VT-Mapper block.
