A patch panel is required in order to connect the high-density interface connector to individual T1/E1
lines.
Note
Figure 58: T1/E1 Cable Connector
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 are attached 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).
