Connecting a Videophone
Many videophones interchange with the ISDN exchange the same information as netMod,
for the establishment-answer of a call.
For this reason, in order to answer a videophone call, the following steps are suggested:
• Assign MSN numbers (MSN service) to the data port, so as to prevent a PC
connected to netMod port from answering a videophone call. In case of an incoming
videophone call, the call must have a called party number different from the MSN
number assigned to the data port.
Assign MSN numbers forcing netMod to compare the called party subscriber number
that follows an incoming call, with the MSN numbers of each port. After this comparison
the call will be driven to the analogue port, or the data port whose MSN number is
identical to the called party number of the call. If the called party number is not identical
to any of the MSN numbers assigned to the analogue ports or the data ports, it will be
driven to the S-bus transparently.
When a videophone device is connected to the S-bus, it is suggested to program MSN
numbers on the videophone device (netMod does not program MSN numbers on the S-
bus). In case of an incoming videophone call, the call will be transparently driven to the S-
bus, because when a port has no assigned MSN numbers, it accepts all the calls. The
videophone will then compare the called party number of the incoming call with the
programmed MSN numbers. If the called party number is identical to an MSN number, the
videophone will accept the call.
Connecting a FAX or MODEM to the Analogue Ports
When a FAX or an analogue Modem is connected to an analogue netMod’s port, it is
suggested:
• to deactivate the CW (Call Waiting) service on this port. An audio tone is generated
when this service is active and can interrupt the transmission of a FAX or the
connection of an analogue modem.
• to assign MSN numbers to this port. In this case the incoming calls from the FAX or
the analogue modem, must have called party numbers identical to one MSN
number of the port, to which the FAX or the analogue modem is connected.
Assigning MSN numbers prevents the devices from answering a call that does not
refer to them.
