Polycom DOC2238A manual To connect the MGC+50 to the Isdn network and T1-CAS network

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:

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.

•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.

ISDN network	ISDN Network connection	ISDN Network connection
connection	for 4 spans	for 8 spans

•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.

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