Step 1: Check the E1 cable type and choose correct impedance value of the E1
interface through the inverter switch.

Step 2: Insert the DB15 connector into the E1 interface of the router.

Step 3: Connect the other end to the right network devices.

For 75

unbalanced coax cable

Connect the cable in this way:

If you choose only a single BNC connector, just connect the BNC connector to the peer
device.

If you choose two BNC connectors (for extending E1 interface cables), connect the
BNC connector of the 75

unbalanced coax cable to a coax connector assembly,

which is connected to a 75

E1 trunk cable. The 75

E1 trunk cable is then connected

to the peer device.

Caution:

Connect the Tx end of the E1 interface cable to the Rx end of the peer unit, and Rx end
of the E1 interface cable to the Tx end of the peer unit.

If the peer device provides the 120

interface, you need to use 75

cable.

For 120

balanced twisted pair cable

Connect the cable in this way:

If you choose only a single RJ45 connector, just connect the RJ45 connector to the
peer device.

If you choose two RJ45 connectors (for extending E1 interface cables), connect the RJ
connector of the 120

balanced twisted pair cable to a network connector assembly,
