ISDN/PSTN Network Services
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 RMX 2000 Getting Started Guide, "Procedure 3:
First-time Power-up and Connection to MCU” on page 2-9.
