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.
3.9.5 Connecting the Interface Cable
Caution:
Before you connect a port, read its label carefully; a wrong connection can impair the
interface module and even damage the device.
You are recommended to install a special lightning arrester at the input end of the
interface cable for better lightning protection.
Step 1: Insert the DB-68 connector of the 8T1 conversion cable to the DB-68 port on the
MIM-8T1/MIM-8T1-F module.
