To connect the BNC connectors of the E1 75-ohm cable to the remote network device:
1. Connect the D15/D68 connector of the E1 75-ohm cable to the D15/D68 interface of the
interface module and fasten the bolts to fix the cable.
2. The other end of the cable provides one pair or multiple pairs of 75-ohm BNC connectors.
Connect the TX connectors and the RX connectors on this end to the RX connectors and the TX
connectors on the remote device, respectively.

To extend the cable:
1. Connect each BNC connector of the E1 75-ohm cable to one end of a coaxial connector.
2. Connect the remote device to the other end of the coaxial connector through an E1 75-ohm
trunk cable.

If the impedance of the E1 interface on the remote device is 120 ohms, you must use an impedance
converter to adapt the impedance.
