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.
LINK
OFF means the link is not connected and ON means the link is
connected.
ACTIVE
OFF means no data is being transceived on the interface and blinking
means data is being transceived.
