Interface cable
The FIC-8E1/FIC-8E1-F module provides eight E1 ports and adopts a 120-ohm or a 75-ohm 8E1
conversion cable. The two types of cables look similar. Both of them have a DB-68 connector at one
end for connecting the router. At the other end, however, the 75-ohm 8E1 conversion cable provides 16
coaxial cable connectors; and the 120-ohm 8E1 conversion cable provides eight twisted pair cable
connectors, as shown in the following figures:
