Configuring the ISDN interface
To configure the ISDN interface, do as follows:
1. Select SETTINGS > Interfaces > ISDN.
2. Select whether the ISDN interface should be Enabled or Disabled.
3. Select whether the 38 V power output of the ISDN interface should be Enabled or Disabled.
If the connected ISDN device is self-powered, you should disable 38 V power.
4. For each ISDN port, set the call type(s) for incoming calls.
You can select Standard, 3.1 kHz Audio, UDI and/or RDI.
5. For each ISDN port, set the MSN numbers that are to be assigned to each call type.
Note that this setting only applies to the call type selected above the MSN number, and only if
the connected device supports the call type used.
You have the following options with the MSN numbers:
<None>. No MSN numbers are used. An incoming call is accepted in all devices connected
to this port.
1*, 2*, 3* or 4*: If, for example, you select 1* at Standard call type for port 1, an incoming
Standard call is accepted by all devices on port 1 that are programmed with the number 1*.
0401....0408: These are local numbers for separate devices connected to port 1.
0411....0418: These are local numbers for separate devices connected to port 2.
An incoming call is accepted by devices that are programmed with the selected number and
connected to the correct port.
You can combine the MSN settings.
Example: You have two devices connected to the same port. One is programmed with the
numbers 1* and 0401, the other is programmed with 1* and 0402.
In the web interface, you select the MSN number 1* under Standard.
If an incoming Standard call arrives, both devices will accept the call.
If you make a local call to one of the local numbers 0401 or 0402, only the called
device will accept the call.
Note
Connected devices will only receive incoming calls with the call types that are
selected here.
For example, if only Standard is selected for port 1, and a G4 fax call (using call type
UDI) arrives, a fax connected to port 1 will not receive the incoming call.
Important
If you set an MSN number to anything other than <None>, all connected
devices must be programmed with MSN numbers.
