Install the External Modem

The U.S. Robotics Sportster Model USR 33.6 EXT external modem is the recommended external modem. Avaya CMC1 Media Gateways operate with this modem set to the factory default settings.

You may use a locally obtained, type-approved external modem (33.6 kbps and V.34 protocol). Contact your Avaya Inc. representative for more information.

2.Route the MODEM cable (P2) from the Processor Interface Cable through the cable trough and to the modem.

3.Connect the cable to the modem. Refer to Processor Interface Cable Pinout on page 165 for the pinout of the modem cable.
