Interface Cable FIC-2VE1 interface cables are G.703-compliant 120-ohm balanced twisted pair cables. At one end of the cable is a DB-15 male connector for the connection to the Router, and at the other end is an RJ-45 connector for the connection to the network.

Figure 245 E1 120-ohm balanced twisted pair cable

If the cable with the resistance of 75-ohm is needed, a 75-ohm-to-120-ohm cable adapter (one end is BNC connector and the other end is RJ-45 connector) which is illustrated in the following figure can be installed.
