ISDN/PSTN Network Services

Polycom RealPresence Collaboration Server (RMX) 1500/2000/4000 Administrator’s Guide

To enable ISDN and PSTN participants to connect to the MCU, an ISDN/PSTN Network Service must be defined. A maximum of two ISDN/PSTN Network Services, of the same Span Type (E1 or T1) can be defined for the RMX. Each Network Service can attach spans from either or both cards.

Most of the parameters of the first ISDN/PSTN Network Service are configured in the Fast Configuration Wizard, which runs automatically if an RTM ISDN card is detected in the RMX during first time power-up.For more information, see the RealPresence Collaboration Server (RMX) 1500/2000/4000 Getting Started Guide, "First Entry Power-up and Configuration” on page 2-25.
