H3C MSR 20 - Connecting the Interface Cable

MIM-2VE1 Module 119
Interface Cable MIM-2VE1 interface cables are G.703-compliant 120-ohm balanced twisted pair
cables. At one end of the cable is a DB-15 male connector for the connection to
the Router, and at the other end is an RJ-45 connector for the connection to the
network.
Figure 134 E1 120-ohm balanced twisted pair cable
If the cable with the resistance of 75-ohm is needed, a 75-ohm-to-120-ohm cable
adapter (one end is BNC connector and the other end is RJ-45 connector) which is
illustrated in the following figure can be installed.

CAUTION:
■ For the convenience of extending the connection of E1 120-ohm balanced
twisted pair cable, you can use network interface connector.
■ E1 120-ohm balanced twisted pair cable, network interface connector,
75-ohm-to-120-ohm adapter are optional accessories. Please select one when
purchasing a MIM-2VE1 module; by default, they are not provided.
For cable pinouts, see Low-End and Mid-Range Series Routers Cable Manual.
