Adding/Modifying ISDN/PSTN Network Services
You can use the RMX Management – ISDN/PSTN Network Services section
of the RMX Web Client to add a second ISDN/PSTN Network Service or
modify the first ISDN/PSTN Network Service.

Obtaining ISDN/PSTN required information

Before configuring the ISDN/PSTN Network Service, obtain the
following information from your ISDN/PSTN Service Provider:
•Switch Type
Line Coding and Framing
•Numbering Plan
•Numbering Type
Dial-in number range
A new ISDN/PSTN Network Service can be defined even if no RTM ISDN card
is installed in the system.
If the RMX is connected to the public ISDN Network, an external CSU or similar
equipment is needed.
