FEATURE
DESCRIPTION
The Electra Elite 48/192 system supports up to four Door/Monitor telephones.
A doorphone can be called by a station user or a station (or number of
stations) can be signaled when a doorphone call button is pressed. When a
station answers the doorphone ringing, a 2-way speech path is established.
In addition to the doorphone ringing assignment, both the tone and cadence of
doorphone ringing can be defined. This offers an easy way for the station user
to distinguish a doorphone call from any other type of call.
The Door/Monitor Telephone works closely with the Door Lock Release
feature, and the DPH(4)-U10 ETU that supports both features.
