Amplified Ringing Tone with answer in station
Amplifier disabled by station
Feature Description
The audio signal of incoming calls can be amplified as an extra indication of the call. The feature require a station and a separate speaker for distribution of the amplified calling tone. It is not possible to answer the call through the separate speaker.
Operation
As a call is made to the station, the corresponding RCO triggers a relay which controls the amplifier, and makes it turn on. This is repeated for every calling tone if the station is in PRIVATE position. When the call is answered the amplifier will be switch on and off by the callers M-key. To disable the amplifier the called party lifts the handset or presses a digit on the keypad.
