INTERCONNECTING THE EQUIPMENT AE/LZB 119 1894 R1A

INTERCONNECTING THE

EQUIPMENT

A C3 Maestro dispatch console system equipped with

an Enhanced Audio Enclosure requires the following

interconnections. See Figure 1:

•

PC-to-CEC/IMC Data Concentrator Card

control data link

– Via twisted pairs, phone lines,

punch blocks and/or 4-wire modem equipment. A

100-foot (30.5 meters) pre-wired cable is supplied

for co-located RS-422 hook-ups.

•

Enhanced Audio Enclosure-to-CEC/IMC Audio

Concentrator Card audio link

– Via 600-ohm

twisted pairs, phone lines, punch blocks and/or mux

equipment. A 100-foot (30.5 meters) pre-wired

cable is supplied for co-located audio hook-ups.

•

PC-to-Enhanced Audio Enclosure control data

link

– A 9-foot (2.74 meters) pre-wired cable is

supplied for this control data link. (In some very

specialized applications, the console does not

require an audio system; therefore this

interconnection and all audio-related

interconnection information within this manual can

be ignored. However, since this configuration is

very rare, all procedures in this manual assume the

console is equipped with an audio system, unless

otherwise noted.)

•

PC-to-Video Display Monitor

•

PC, Video Display Monitor and Enhanced

Audio Enclosure AC Power Connections

In addition, the following connections are required if

the related external devices are used with the console:

•

Enhanced Audio Enclosure-to-Dispatch

Keyboard

•

Enhanced Audio Enclosure-to-Desk Mic

•

Enhanced Audio Enclosure-to-Supervisor

Headset Jack Box

•

Enhanced Audio Enclosure-to-Operator

Headset Jack Box

•

Enhanced Audio Enclosure-to-Boom/Gooseneck

Mic

•

Enhanced Audio Enclosure-to-Boom/Gooseneck

PTT and Monitor Switches

•

Enhanced Audio Enclosure-to-Footswitches

•

Enhanced Audio Enclosure-to-Speaker

Assemblies

•

PC-to-Standard PC Keyboard

– The standard PC

keyboard is only utilized during console start-up

and maintenance operations.

In addition, the following interconnections are required

for optional equipment, if employed:

• •

Enhanced Audio Enclosure-to-Recorder

Equipment

•

Enhanced Audio Enclosure-to-Pager (Paging

Encoder)

— Connections required only if paging

operations are necessary but internal Enhanced

Audio Enclosure paging circuits are not utilized.

•

Enhanced Audio Enclosure-to-External

Equipment Controlled by Relay Form-C

Contacts

•

Enhanced Audio Enclosure-to-Call Director

NOTE

Unless otherwise noted, all procedures in this

manual should be performed in the order presented.

CEC/IMC INTERCONNECTIONS

The C3 Maestro console interfaces to the CEC/IMC via

a full-duplex serial control data link and a 4-wire audio

connection for the select audio and microphone link. In

addition, each unselect speaker at the console requires an

additional 2-wire connection from the CEC/IMC. Also, if

the console is interfaced to a Call Director for Call Director

telephone patch operations, an additional 4-wire audio link

between the C3 Maestro and the CEC/IMC is required. See

Figures 1 and 7 and Table 7.

As shown in Figure 7, all interconnections at the

CEC/IMC are made via Concentrator Cards. These cards are

located at the back of the CEC/IMC cabinet. Control data

connections are made via Data Concentrator Cards and

audio connections are made via Audio Concentrator Cards.

Typically, as shown in Figure 7, these connections are

extended out of the CEC/IMC cabinet via Telco cables and

terminations are actually made at punch blocks located

external of the CEC/IMC cabinet.

CEC/IMC Concentrator Card pin-out details are listed

on the customer-specific system documentation print-outs.

These print-outs are included with the CEC/IMC when it

ships from the factory. See the CEC/IMC Digital Audio

Switch Customer-Specific System Documentation

maintenance manual, LBI-38939 for sample print-outs and

complete print-out explanations.
