Power fail

When planning the extension wiring for the system, consideration should be given to the use and location of Featurephones and 2-wire extensions.

Analogue

In the event of a total system power failure, at least 50% of the equipped lines are switched to extensions. Lines 1 and 2 are power-failed to extensions 26 and 27, the last two extensions on the basic unit. Line 5 is power-failed to extension 34 and

Line 7 to extension 35, the last extensions on each of the expansion boards. These line positions are summarised in the table below.

Note: If lines are power-failed to extension positions equipped with Featurephones, the user must replace the Featurephone with a standard 2-wire phone to answer or make calls. FEATUREPHONES CANNOT BE USED IN POWER FAIL.

ISDN

In the event of a total system failure, the ISDN lines will not operate. ISDN devices can be connected directly to the ISDN NTE or an external S bus, and work independently of the system.
