The following figure illustrates the 8T1 conversion cable for the FIC-8T1/FIC-8T1-F module.
Figure 4-57 8T1 conversion cable
At one end of the cable is a DB-68 connector for connecting the router and at the other end are eight
RJ-45 connectors for connecting other devices.
Connecting the interface cable
Before you connect a port, read its label carefully; a wrong connection can impair the interface module
and even damage the device.
If the interface cable is routed outdoors, you are recommended to install a special lightning arrester at
the input end of the interface cable for better lightning protection.
Step1 Insert the DB-68 connector of the 8T1 conversion cable to the DB-68 port on the FIC-8T1/FIC-8T1-F
module.
Step2 Connect one RJ-45 connector at the other end of the cable to the device to be connected.
Step3 Power on the router. Check the behavior of the LINK LED on the module panel: OFF means fault
occurs on the line. Check the line status.
