Note:

You can select a network interface connectors with an RJ-45 receptacle at both ends that connect two 120-ohm balanced twisted pair cables with BNC connectors. The network interface connector is used in the extension connection with E1 120-ohm balanced twisted pair cables.

In addition, a 75-ohm to 120-ohm adapter is provided.

For the pinouts of E1cables, see Low-End and Mid-Range Series Routers Cable Manual.

Caution:

E1 cable, coaxial connector, network interface connector and 75-ohm to 120-ohm adapter are all optional accessories, you need to order them when purchasing 2-port modules; otherwise, they are not provided.

II. Conversion cable for 4-port module

4-port modules provide two types of “1-to-4” conversion cables: 120-ohm 4-port module conversion cable and 75-ohm 4-port module conversion cable. At one end of these two types of cables is a DB-25 connector used to connect a router, and at the other end are four DB-15 connectors used to connect E1 cables. You can distinguish these two types of cables by the main labels. There are the words “4-port module -120Ohm-CAB “ printed on the main label for 120-ohm 4-port module conversion cables whereas the words “4-port module -75Ohm-CAB” are printed on the main label for 75-ohm 4-port module conversion cables.

The two types of cables have a similar appearance, as illustrated in the following figures. However, a 75-ohm 4-port module conversion cable uses 8-core coaxial cables but a 120-ohm 4-port module conversion cable uses four twisted pair cables.
