To connect the MGC+ to the ISDN network or T1-CAS Network:
• Connect the 8-pin RJ-45 connector of the network cable to the NET
RJ-45 jack on the rear panel of the MGC+. Repeat this step for each of
the ISDN network lines to be connected to the Network Interface card
installed in the MCU.

Leased lines should be connected using an adapter with a screw
connector with solid conductor wires or a similar adapter.
• Connect one side of the adapter to the NET RJ-45 jack on the rear panel
of the MGC+. Then connect the leased line wires to the other side of the
adapter.
