Communication With An Isdn Modem - Intracom netMod User Manual

Communication with an ISDN MODEM

In case of an incoming data call from an ISDN modem, it is suggested to assign MSN
numbers to the data port. In case of an incoming call from an ISDN modem, the call should
have a called party number identical to the one of the MSN numbers assigned to the data
port.
When the analogue or the data ports have no MSN numbers
assigned, they accept any call (netMod does not make any
comparison of numbers).
When the device connected to the S-bus has no MSN numbers
assigned on its memory, it accepts any call.
