RJ48C
The TelCo Connector Panel (TCCP) provides a convenient way to connect the cable shields to
chassis ground. Generally, this needs to be done only when the system is initially installed. If your
system was installed by Avaya field support, grounding is already configured. However, if you
previously connected to a non-shielded interface, and need to connect to equipment using shielded
cables, jumpers must be installed in the TCCP to ground the shields.
Each RJ48C module is supplied with spare, uninstalled jumpers. Remove the two screws that
secure the RJ48C module to the TCCP and unplug the module from the backplane. On JP1, remove
one of the jumpers from its STORE WHEN NOT USED position and install it in the SHIELDS 6
position (across JP1, pins 5 and 7). This grounds the pin 6 shields (transmit lines) for all eight span
connectors on the module.
Generally, the other spare jumper remains in the unused position. The shields for the receive lines
are grounded at the connected equipment. Alternatively, ground the receive lines by moving the
spare jumper to the SHIELDS 3 position (across JP1, pins 6 and 8). Each shield grounds at only
one termination, as shown in the preceding interconnection diagram. Do not ground a shield at both
ends.
