Connect twisted pair (120 ohm) to E1 network

The Model 3088/K is equipped with a single RJ-48C jack for connections to a 120 ohm twisted pair E1 net-
work interface. If your E1 network terminates via RJ-48C, use the diagram below and the table following it to
make the proper connections. The connector pinout and signals are shown in
Use the following connection diagram to connect the 120-ohm E1 network channel.

Connecting dual coaxial cable (75 ohm) to E1 network

The Model 3088/K is also equipped with dual female BNCs (TX and RX) for connection to a 75 ohm dual
coax E1 network interface. If your E1 network terminates via dual coaxial cable, use
proper connections.
