6. Connect the access lines to the distribution frame. Cross-connect
them to the corresponding Controller and Line Module lines
according to the Controller and Line Module wiring charts.
7. Use the COMPANION 200 Programming Record to ensure that
the correct mapping between Controller access line port,
Controller access line number, distribution frame number, and
host switch telephone number is recorded.
Before you begin, you need the following material:
• Controller: Two 25-pair, 0.5 mm (24 AWG) cables with a female
RJ21 connector installed at one end.
• Base Station Modules: For each Base Station Module, one
25-pair, 0.5 mm (24 AWG) cable with a female RJ21 connector
installed at one end.
To cross-connect the Controller and Base Station Module wiring,
follow this procedure:
1. Plug the RJ21 connector of each 25-pair cable into the
corresponding TCM connectors on the Controller and the Base
Station Module or Modules. These connectors are identified by
an icon of a telephone:
2. For each RJ21 connector, turn the RJ21 connector latch so it
covers the connector. Tighten the latch screw to hold the
connector in place.
3. Route the 25-pair cables through the upper shelf of the cable
troughs to the distribution frame.
Note: Route the 25-pair cables straight out to one side of the
cable trough in a bundle. Use cable ties to secure them to
the wall and to support their weight. This prevents undue
stress on the cable trough shelf when there are several
25-pair cables.
