Connecting T1/E1 cables

The physical layer interface for the Cisco ASR 903 Router T1/E1 port is a customer-installed high-density connector. The high-density connector has thumbscrews which should be screwed into the interface when the cable is installed.

Figure 3-25shows the T1/E1 cable connector and Figure 3-26shows the connection between the T1/E1 interface and the patch panel.

Note A patch panel is required in order to connect the high-density interface connector to individual T1/E1 lines.

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).
