13.5 Programming Multiple Subscriber Numbers (MSN)

By programming an MSN number, each phone of the ISDN bus can be directly addressed upon an incoming call. This of course requires that this “dial-in” number is known to the caller. If no MSN has been programmed, the ISDN phone will accept all calls to the ISDN bus. With MSN’s programmed, the phone will only react to calls received with one of the MSNs programmed. The Deskmaster 510i sup- ports 3 MSNs for voice calls and a fourth one for data calls. The Deskmaster 520i has an additional MSN number for the analog port. To the MSNs for voice calls a personalised ringing tone can be assigned. Consult your network provider for more MSN numbers on you ISDN line.
