Night Service

When the exchange is in Night Service mode, all your incoming calls to the operator are transferred to a selected extension or group of extensions. The exchange is equipped with three different Night Service modes:

Common Night Service

All incoming calls to the operator are transferred to one specific extension. Answer the call in the normal way.

Individual Night Service

Selected external calls to the operator are transferred to one specific extension. Answer the call in the normal way.

Universal Night Service

All incoming calls to the operator are transferred to a universal signalling device, e.g. the common bell. Answer the call as described in section “Common bell group” on page 68.

Alarm extension

An extension can be programmed by your system administrator as an Alarm extension. A call to an Alarm extension obtains automatic Intrusion if the extension is busy. Up to seven calling parties may be connected at the same time.
