Connecting Cables to SFP Modules
For information on connecting cables to Cisco optical and Ethernet SFP interfaces, see

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.
Patch panels are required in order to connect the high-density interface connectors to individual T1/E1 lines.
Note
Installing the Cable Connectors
16 x T1/E1 Cable Connectors
The 16 x T1/E1 interface module requires a patch cable (see Recommended Patch Panel). One end of the
cable (see the figure below ) 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).
