Connecting the MGC+100 to the Network
To connect the MGC+100 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+100. Repeat this step for each
of the ISDN network lines to be connected to the Network Interface card
installed in the MCU.
Figure 2-9: ISDN network connection
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+100. Then connect the leased line wires to the other side of
the adapter.
The ISDN network is optional. If the MGC+100 has to be connected to the public
ISDN network then an external CSU or similar equipment is needed.
T1-CAS network is optional. It allows you to connect Audio Only participants to
conferences via T1-CAS lines. It uses the same network connections as ISDN
and the procedure described below is applicable to both ISDN and T1-CAS
lines.

The ISDN and T1-CAS network properties must be defined in the Network
Services. For details, see the MGC+ Administrator’s Guide, Chapter 3.
