z
OFF means no carrier signal has been received.
ACTIVE

Interface cable
1) Interface cable of the FIC-1E1/FIC-2E1 and the FIC-1E1-F/FIC-2E1-F
Interface cables for the FIC-1E1/FIC-2E1 and FIC-1E1-F/FIC-2E1-F 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.
Figure 4-37 E1 75-ohm unbalanced coaxial cable
To extend an E1 75-ohm unbalanced coaxial cable, 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.
