Connecting a 1/2/4/8-port E1 75-ohm cable (D15/D68 <----> BNC)
CAUTION:
Make sure you insert the cable into the right interface so as to avoid damages to the interface
module or the chassis.
•
If you do not need to extend the cable, you can directly connect the BNC connectors of the E1
75-ohm cable to the remote network device as follows:
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.
