Interface Cable

The ROUTER 4-PORT E1 IMA FIC card provides four E1 ports and adopts a 120-ohm
or a 75-ohm 4E1 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 4E1 conversion cable provides eight coaxial cable connectors;
and the 120-ohm 4E1 conversion cable provides four twisted pair cable connectors.
The card provides eight E1 ports and adopts a 120-ohm or a 75-ohm 8E1 conversion
cable. The two types of 8E1 conversion cables are similar to the two types of 4E1
conversion cables except that 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:
