4.7.4Interface Cable

I.Interface cable of the Router 4-Port CE1/PRI FIC

Interface cables for the Router 4-Port CE1/PRI FIC are G.703-compliant cables, also known as E1 cables. The cables are divided into two categories: 75-ohm unbalanced coaxial and 120-ohm balanced twisted-pair.

z 75-ohm unbalanced coaxial cable

As shown in the following figure, at the router end of the cable is a DB-15 plug and at the network end are two BNC receptacles.

( Note:

To extend an E1 75-ohm unbalanced coaxial cable, you can select a pair of coaxial connectors with a BNC receptacle at each end to connect the BNC receptacles of the cable each to a 75-ohm unbalanced coaxial cable with BNC connectors.

z 120-ohm balanced twisted-pair cable

As shown in the following figure, at the router end of the cable is a DB-15 plug and at the network end is an RJ-45 connector.
