Interface cable

Interface cables (T1 cables) for MIM-1T1/MIM-2T1/MIM-4T1 and MIM-1T1-F/MIM-2T1-F/MIM-4T1-F
modules are 100-ohm straight-through shielding network cables, as shown in the following figure:

Figure 3-51 T1 cable

In addition, you may use a network interface connector to extend a T1 cable. Both ends of the connector
are RJ-45 jacks that can connect two network cables.

Both T1 cable and network interface connector are optional accessories. Please order them together
with the MIM-1T1/MIM-1T1/MIM-4T1 or MIM-1T1-F/MIM-2T1-F/MIM-4T1-F module. By default, they
are not provided.

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

Connecting the interface cable

Read the mark identifying a port before you connect a cable to it, making sure it is the correct port.
Wrong connection tends to damage interface modules and even the Router;

Some protection measures are taken for MIM-1T1/MIM-2T1/MIM-4T1 module. Still, you are
recommended to install a special lightning arrester at the input end of the cable leading to the
outdoors in order to protect the line against lightning strikes more efficiently.

Step1 Insert one end of a T1 cable into the RJ-45 connector on the T1 or T1-F module;

Step2 Connect the other end of the cable to the device to be connected:
