4.3.6 ISDN Interface Properties
See Figure 4-7. To establish Integrated Services Digital Network data communication, connect the BGAN terminal
ISDN port to ISDN equipment using the ISDN/Ethernet cable. Use the ISDN Interface page to activate 40 V power
sourcing on the ISDN interface, and set Multi-Subscriber Numbering (MSN) numbering options.
ISDN Power Sourcing: To turn on the ISDN power sourcing, click on the On radio button. The ISDN device should
receive 40 V power immediately via the ISDN cable. This field should be on unless the ISDN is not being used or
the ISDN device has its own power source.
MSN Speech: By default, MSN 1 is entered into the MSN Speech number text box. To receive incoming calls,
configure the same MSN into the ISDN handset connected to the ISDN port.
MSN 3.1 KHz audio: By default, MSN 2 is entered into the MSN 3.1 kHz Audio number text box. To receive
incoming calls, configure the same MSN into the ISDN fax machine connected to the ISDN port.
MSN UDI: By default, MSN 3 is entered into the MSN Unrestricted Digital Information text box. UDI is a 64 kbps
service that is a European standard ISDN.
