REMOTE CONTROL
DTMF tones may be sent from one intercom station to the other for remote control. The keypad on
the station sends standard telephone dialing tones (CCITT). This is mainly used for electric door-lock
release and for dialling out to the public telephone network (PTT). The microphone mute function must
be activated while pushing a number key to disable conference add-on . When the B-subscriber
(receiver of the call) is programmed with the privilege “DTMF Device” then the number keys may be
activated without pushing the microphone mute key.
CAMP ON BUSY EXTENSION
The caller may camp-on to a busy extension for 20 seconds (programmable subscriber timer),
after which the call will be automatically cancelled. If the called party becomes free within this time,
the connection will be established with warning tone to both parties.
PRIVACY
The stations privacy switch controls the privacy status. When the B-subscriber is in privacy both
stations get the ringing tone. The B-subscriber may accept the call by pressing the 0-button within 15
seconds (programmable subscriber timer). This operation is valid when the B-subscriber is not using
personal queue.
