3.7.4 Interface Cable
The MIM-8E1/MIM-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:
