244 Feature Guide
1.19.1.11 ISDN Extension
Description
An ISDN port can be used for either trunk or extension connection. When extension connection is enabled,
ISDN terminal devices (e.g., ISDN telephone, G4 fax machine, PC) or a behind PBX can be connected to
the port.
If the ISDN port is in point-to-point (P-P) configuration, one terminal device can be connected to the port. If
the ISDN port is in point-to-multipoint (P-MP) configuration, a maximum of eight terminal devices can be
connected to the port. However, only a maximum of two devices can be used simultaneously.
Individual terminal devices on a behind PBX can be addressed with Multiple Subscriber Number (MSN).
The MSN consists of the ISDN extension number and an additional digit, 0 through 9 or 00 through 99.

Conditions
• Subaddressing
Subaddressing is possible between ISDN terminal devices. The subaddress goes through the PBX to
the ISDN terminal devices directly.
• Call Transfer (PBX feature) is available only for ISDN extensions in P-MP configuration. (
