AT&T Door Phone Controller - Manual (Page 14)

The AT&T Door Phone Controller
The AT&T Door Phone Controller provides multi-functional
control for communications to a dedicated door-speaker unit
and a remote door-unlocking device. The AT&T Door Phone
Controller (see Figure 1-1) can be used alone, or it can be
used along with a PBX (Private Branch Exchange) or
communications system to alert personnel within a residence or
building that someone is requesting attention at the entrance.
Operating the unit is simple: when the push button on the door
speaker is pressed, the AT&T Door Phone Controller unit
signals a telephone station(s) and can activate an auxiliary
alerting device (such as a door bell, chime, or tone generator)
within the home or building. Upon hearing the ringing telephone
and/or alerting device, answer the phone and have a two-way
phone conversation with the person at the door. The person
inside the building can also remotely unlock the door, either by
entering a numeric code (Door Code) on the telephone’s
touch-tone keypad, or by pressing a button.
