When used in any mode of a System 25, if the user initiates a call to the door and he wishes to enter the
Option Selection mode, pressing three pound keys followed by the digit 3 (i.e., # # # 3, not # # 3) must be
entered. Actually, the first # does not seem to be recognized at any time during the call. However, it should be
noted that only # # 3 is needed to enter the Option Selection mode when the call is initiated from the door
button press.
When sharing a trunk port on a System 25, that port
must be configured as an “805” PBX/Centrex, not an
“801” Loop trunk. This is the only way to transmit a
hook flash to that port.
On the Merlin 1030/3070 tip and ring station application,
there is a preset delay such that the Merlin system will
disregard DTMF for the first 12 seconds of the connection. In this mode, users have the choice of either
changing that time period or waiting for it to time out for
each call.
In general, the ring-cadence option selection applies
only if there is an auxiliary alert device connected. All
of the EKTS/PBX’s will “absorb” the ringing signal from
the AT&T Door Phone Controller and generate their
own ring cadence to the telephone sets.
When using the AT&T Door Phone Controller in any configuration with a Merlin System, the pound key must be
pressed twice (##) for each pound (#) sent to the unit
when dialing from a multi-button set.
Port Saver/Trunk Saver operation will not work for
Tip/Ring sets. A switch-hook flash is not passed to the
trunk port from these sets.
A trunk shared with the AT&T Door Phone Controller
should not be placed in a trunk pool with other trunks.
When the AT&T Door Phone Controller shares a C.O.
trunk, Trunk Saver operation is recommended.

Tip/Ring telephone sets connected to the Merlin System
through a BTMI cannot use Port Saver/ Trunk Saver op-
eration. The BTMI wiII not transmit the required
hook-flash signal.
System 75 requires a pound (#) to be dialed at the end
of every dial string. This is required to send the dialed
number to the trunk port.
Tip/Ring telephone sets cannot be used in this mode to
access the AT&T Door Phone.
For PARTNER telephone sets not equipped with a Re-
call button, “FEATURE 03” must be dialed to send a
hook-flash signal to the trunk port.
In the Ringdown mode, no number should be programmed in the AT&T Door Phone for it to dial when
the door button is pressed. The PARTNER Plus system
should be programmed to alert the desired stations
when the door phone goes off-hook on its station port.
The information for this system is based on engineering
judgment.

1-2 Introduction
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.
Features
■ Control for remote door unlocking
■ Voice communications with door speaker
■ Door ajar detect
■ Interface for door bell, chime, or tone generator
■ Selectable option functions (from touch tone telephone)

2-8 Installation Procedures
AT&T Door Phone Controller Location
You need to determine exactly where you want the unit
installed and how you want it configured. Another consideration
is what components will be used with the AT&T Door Phone
Controller. Here are some questions that must be answered
prior to installation:
■ Do you currently have a door speaker installed?
■ Do you have a business telephone system (PBX or EKTS)?
■ Do you have a remote door unlock mechanism (electric
door strike) installed?
■ Do you have an auxiliary alert system (door chime) currently
installed?
■ Do you have a door ajar switch installed?
The AT&T Door Phone Controller is designed to control the
functions of the components mentioned above, and how you
answer these questions will determine how the AT&T Door
Phone Controller will be installed, optioned, and operated.
When selecting options for your AT&T Door Phone Controller,
e.g., to change the door-unlock security code, the AT&T Door
Phone Controller unit must be DIP switch selected to Option
Selection mode. For this reason you may want to install the
AT&T Door Phone Controller unit in a secure area which has
access only by authorized personnel. If you are installing the
unit in a business environment (currently have PBX/EKTS), you
may wish to install the unit along with the telephone equipment.
