LED	Description
LINK	OFF means no link is present; ON
	means a link is present.
ACTIVE	OFF means no data is being
	transmitted or received. ON means
	data is being transmitted or received.

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:
