D/120JCT-LS Configuration Diagram

Functional Description

The D/120JCT-LS board connects 12 analog loop start

telephone lines to 12 onboard call processing

resources or to other resources via the CT Bus.

This board provides:

■Interference suppression

■Ring and on-hook/off-hook signaling control

■Tone detection and generation

■Digitization and playback of voice files

The signals from the 12 loop start telephone lines

connected to the D/120JCT-LS board first pass through

a telephone line interface that provides transient

protection and electromagnetic interference (EMI)

suppression (see daughterboard block diagram).

These telephone line interfaces use reliable, solid-state

hook switches (no mechanical contacts) and FCC-Part

68 Class A ring voltage and Class B ring frequency

circuitry. This FCC-approved ring detector is less

susceptible to spurious rings created by random

voltage fluctuations on the network. Each interface also

incorporates circuitry that protects against high-voltage

spikes and adverse network conditions and allows

applications to go off-hook any time during ring

cadence without damaging the board.

The telephone line interface applies the inbound signal

including the ring and on-hook/off-hook signals to

analog/digital inputs of a signal converter called a

codec (COder/DECoder) that samples and digitizes

these signals. These digitized signals are sent to a

QSLAC chip where they are routed via the CT Bus

either to an onboard Motorola* 56303 Onyx DSP or to

an external resource on any of the 1024 CT Bus time

slots. This enables the application to reroute calls to

any added resource, such as speech recognition,

facsimile, or text-to-speech (TTS).

Functional Block Diagram

Part of the D/120JCT-LS board’s telephone inter face

includes an on-hook audio path that detects Caller ID

information. Depending on the level of service offered

by the local telephone provider, Caller ID can include

the date, time, caller’s telephone number, and the

name of the person calling (in some enhanced Caller

ID environments). The on-hook audio path can also

detect touchtones while the line is on-hook. This capa-

bility lets developers use the D/120JCT-LS board

behind PBXs that require on-hook touchtone detection

for signaling.

When the onboard call processing resources are used,

the network signals are extracted and passed to the

onboard control processor, which can change channel

status and communicate channel events to the applica-

tion via a shared RAM and the host PC PCI bus.

The Motorola 56303 Onyx DSP processes the digitized

voice data based on Spring Ware firmware loaded in

code/data RAM. Each Motorola 56303 Onyx DSP per-

forms the following signal analysis and operations.

On the incoming data:

■Applies automatic gain control (AGC) to compensate

for variations in the level of the incoming audio signal

■Applies an Adaptive Differential Pulse Code

Modulation (ADPCM), Pulse Code Modulation (PCM)

algorithm, G.726 32 Kb/s coding or GSM, to com-

press the digitized voice and save disk storage

space

■Detects the presence of tones (DTMF, MF, or an

application-defined, single or dual tone)

■Detects silence to determine whether the line is quiet

and the caller is not responding

For outbound data:

■Expands stored, compressed audio data for play-

back

■Adjusts the volume and rate of speed of playback

upon application or user request

■Generates tones — DTMF, MF, or any application-

defined general-purpose tone

The dual-processor combination also performs the fol-

lowing outbound dialing and call progress monitoring:

■Transmits an off-hook signal to the telephone network

■Dials out (places an outbound call)

■Monitors and reports results: line busy or congested;

operator intercept; ring, no answer; or if the call is

answered, whether answered by a person, an

answering machine, a facsimile machine or a modem

When recording speech, the Motorola 56303 Onyx DSP

can use digitizing rates from 24 to 64 Kb/s as selected

by the application for the best speech quality and most

efficient storage. The digitizing rate is selected on a

channel-by- channel basis and can be changed each

time a record or play function is initiated. The DSP-

processed speech is transmitted by the control proces-

sor to the host PC for disk storage. The D/120JCT-LS

board can record incoming signals with the telephony

interface in either the high-impedance on-hook state or

the normal off-hook state. When replaying a stored file,

the processor retrieves the voice information from the

host PC and passes it to the Motorola 56303 Onyx

DSP, which conver ts the file into digitized voice. The

DSP sends the digitized voice responses to the codec,

which is controlled by three QSLAC chips. The codec

converts the digitized voice into analog voice and

sends the voice response to the caller via the tele-

phone line interface.

Although this product is capable of recording incoming

signals in an on-hook state, applications such as call

logging should use the D/160SC-LS-HiZ (ISA form

factor), which is specifically designed for analog high-

impedance recording.

When the system is initialized, Spring Ware firmware is

downloaded from the host PC to the board. Spring

Ware controls all board operations and gives the board

all of its intelligence and enables easy feature

enhancements and upgrades.

The onboard control processor controls all operations

of the D/120JCT-LS board via a local bus and interprets

and executes commands from the host PC. This

processor handles real-time events, manages data flow

to the host PC to provide faster system response time,

reduces PC host processing demands, processes

DTMF and telephony signaling before passing them to

the application, and frees the Motorola 56303 Onyx

DSPs to perfor m signal processing. Communication

between the processor and the host PC is via shared

RAM that acts as an input/output buffer and thus

increases the efficiency of disk file transfers. This RAM

interfaces to the host PC via the PCI bus. All operations

are interrupt-driven to meet the demands of real-time

systems. The Board Locator Technology circuit oper-

ates in conjunction with a rotary switch that eliminates

the need to set confusing jumpers or DIP switches.
