Interface
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 3-44 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.
Caution:
Both T1 cable and network interface connector are optional accessories. Please order
them
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.
3.8.5 Connecting the Interface Cable
Caution:
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.
Step 1: Insert one end of a T1 cable into the RJ-45 connector on the T1 or T1-F module;
Step 2: Connect the other end of the cable to the device to be connected:
