MGC+ Hardware and Installation Manual

Connecting the MGC+50 to the PSTN Network 
To connect the MGC+50 to the ISDN network
 
and
 
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.
 
Figure 2-15: ISDN network connection
Leased lines should be connected using an adapter with a screw 
connector for solid conductor wires with a diameter in the range 0.4 to 
0.6 mm. Use Polycom P/N CBL0602A or 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.
This is an optional Network Interface Card. If the MGC+50 has to be connected 
to the public ISDN network then an external CSU or where required, 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.
