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's punch block.
G
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.
