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.

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).
