4.16.4 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:
