Audio Links

Audio Concentrator Cards at the back of the CEC/IMC cabinet provide audio connections at the CEC/IMC. Like the control data connections, audio connections are normally extended out of the CEC/IMC cabinet via Telco cable(s) and line terminations are actually made at punch blocks. See Figure 6A. See the customer-specific system documentation print-outs for Concentrator Card connector pin-out details.

Table 5 shows line requirements between the C3 Maestro and the CEC/IMC for each audio input or output 2- wire 600-ohm twisted pair. Note that two (2) Enhanced Audio Enclosure output pairs, Line 2 out and Line 3 out are never used. These audio output lines are provided for future expansion use.

At the C3 Maestro, audio connections terminate at the DB-25 connector on the Enhanced Audio Enclosure's rear panel. This connector is labeled "LINES 1-4". Its pin-out is shown in Figures 5 and 6A and Table 12. It has female contacts; therefore, the required mating connector is a male DB-25.

Normally, a pre-wired 100-foot (30.5 meters) cable is supplied with the console equipment package for audio interconnections between the Enhanced Audio Enclosure and the CEC/IMC. This 8-pair shielded cable's part number is 19B804083P2. It has a male DB-25 connector on one end for mating to the Enhanced Audio Enclosure's "LINES 1-4" female DB-25 connector. The other end is "pig-tailed" (not terminated) so the cable's 24-guage solid wires can be punched down to the correct terminals at the required CEC/IMC'sG￿punch block.

If cable 19B804083P2 is used, mate its DB-25 to the Enhanced Audio Enclosure, route it to the CEC/IMC, shorten it as required, and punch the wires to the correct punch block's terminals. Wire color coding is indicated in Figure 5 and in the cable's assembly diagram shown at the end of this manual (page 37). Refer to the CEC/IMC customer-specific system documentation print-outs for CEC/IMC Audio Concentrator Card pin-outs which map over to the punch blocks via Telco cables.
