LED	Description
LINK	OFF means no link is present; ON
	means a link is present.
ACTIVE	OFF means no data is being
	transmitted or received. ON means
	data is being transmitted or received.

Interface Cable The following figure illustrates the 8T1 conversion cable for the

MIM-8T1/MIM-8T1-F module.

Figure 109 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

c 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.
