Configuring External Signal Destinations
If a PBX sends an event message, the event message opens a PPP communication
channel via the public network from the PBX to a Terminal Adapter, connected
either directly to a PC with the System Event Manager (SEM) software program or
indirectly via a LAN / WAN (ISDN gateway). Once the event has been confirmed,
the PBX clears down the PPP connection.
There are several possibilities for connecting external signal destinations to a PBX:
Fig. 7.13: Overview of connection possibilities for external signal destinations
Two external signal destinations (1 preferred and 1 alternative external signal des-
tination) can be configured in the Fault & Maintenance Manager.
The PPP via ISDN communication protocol is used for the connection between the
PBX and the external signal destination.
