Installing the Cable Connector

One end of the cable has a 100-pin connector that plugs into the T1/E1 interface module. Use the
thumbscrews on either side of the connector to secure the cable to the interface.
The other end of the cable has two 50-pin Telco connectors that attach to the rear of a 24-port RJ45 patch
panel. Both connectors are identical: one is for Transmit (TX) and the other is for Receive (RX).
