6.11.2 Wiring schemes for the CCI-22 interface module
The CCI-22 interface module connects two 2-wire full-duplex partyline circuits to the matrix
frame .
In the same way as the FOR-22, the CCI-22 dual audio interface module uses both the
RJ-45 connectors on its rear panel for connection to the matrix frame (See also 6.11.1
Wiring schemes for the FOR-22 interface module ).
The top RJ-45 is for the first channel of the interface. The lower RJ-45 is for the second
channel. The DB-9Ms are the interface module’s audio and control inputs and outputs.
Tip: For more information about the CCI-22 interface, see the CCI-22 manual.
6.11.3 Wiring for Clear-Com analog partyline systems
(including Encore)
The two DB-9M connectors are paralleled such that both partyline channels are available on
each connector. It is possible to:
• Wire one DB-9 connector as Channel #1 and the second DB-9 as Channel #2.
• Bring both channels out either DB connector together to create a TW-type partyline
connection.
