Interface cables 4-port Channelized FIC and 4-port Fractional E1 FIC provide two types of 1-to-4 adapter cables, that is, 120-ohm 4E1 adapter cable and 75-ohm 4E1 adapter cable. At one end of both these two types of cables is the DB25 connector used for connecting the Router, and at the other end are four DB15 connectors used for connecting E1 cables. You can distinguish these two types of cables by the main labels. The identifier printed on the main label of 120-ohm 4E1 adapter cables is “4E1-120Ohm-CAB“ whereas the identifier of 75-ohm 4E1 conversion cable is “4E1-75Ohm-CAB”.
The two types of cables have a similar appearance, as illustrated in the following figures. However, the 75-ohm 4E1 adapter cable uses 8-core coaxial cables but the 120-ohm 4E1 adapter cable uses four twisted-pair cables.
