Connecting a 4-port E1 75-ohm cable (D25 <----> D15)
1. Connect the D25 connector of the 4-port E1 75-ohm cable to the D25 interface of the interface
module and fasten the bolts to fix the cable.
2. The other end of the cable provides four D15 connectors. Connect them to the D15 interfaces
on the remote device as needed.

Connecting a 1-port E1 120-ohm cable (D15 <----> RJ45)
1. Connect the D15 connector of the E1 120-ohm cable to the D15 interface on the interface
module and fasten the bolts to fix the cable.
2. The other end of the cable provides one or multiple RJ45 connectors. Connect them to the
RJ45 interface on the remote device as needed.
