The following table describes the LEDs on the MIM-8E1/MIM-8E1-F panel:
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:
