Application Notes (for Compatibility Chart)  
1. When used in any mode of a System 25, if the user initi-  
ates a call to the door and he wishes to enter the  
Option Selection mode, pressing three pound keys fol-  
lowed by the digit 3 (i.e., # # # 3, not # # 3) must be  
entered. Actually, the first # does not seem to be recog-  
nized at any time during the call. However, it should be  
noted that only # # 3 is needed to enter the Option Se-  
lection 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.  
2.  
3. 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 connec-  
tion. In this mode, users have the choice of either  
changing that time period or waiting for it to time out for  
each call.  
4. 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 con-  
figuration 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.  
5.  
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.  
6.  
7. 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.  
8.  
iv  
     
Application Notes (for Compatibility Chart) continued  
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.  
9.  
10.  
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.  
11. Tip/Ring telephone sets cannot be used in this mode to  
access the AT&T Door Phone.  
12. 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.  
13.  
In the Ringdown mode, no number should be pro-  
grammed 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.  
14.  
The information for this system is based on engineering  
judgment.

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  
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.

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.

Operation and Controls Information  
Door Ajar Function  
Default Condition —After the door has been opened by the  
four digit code or the remote push button, the Door Phone  
Controller will wait for the Door Ajar Call-back time-out to  
elapse. At this point if the door is still open, the Door Phone  
Controller will call back the phone/chime for the duration of the  
ring/chime duration and then repeat after the Door Ajar  
Call-back time-out has elapsed again. If the phone is answered  
during that time, a Door Ajar Tone will be heard. The Door Ajar  
Tone will cease when any DTMF Digit is pressed, or the user  
speaks or hangs-up.  
Alternate Condition —If the door is ever opened and the Door  
Ajar Call-back time-out has elapsed, the Door Phone Controller  
will call back the phone/chime for the duration of the ring/chime  
duration and then repeat after the Door Ajar Call-back time-out  
has elapsed again. If the phone is answered during that time, a  
Door Ajar Tone will be heard. The Door Ajar Tone will cease  
when any DTMF digit is pressed, or the user speaks or  
hangs-up.

Installation  
       
Overview  
This section provides installation and operation information for  
applications such as residences or small businesses which do  
not have a telephone system.  
When your AT&T Door Phone Controller is installed with  
standard telephone equipment (no PBX), the unit may operate  
in Shared Line Mode which permits a single telephone set to  
be shared between the AT&T Door Phone Controller and an  
outside line (to a Central Office). Thus, the standard telephone  
equipment can be used for normal call operations as well as  
servicing the door.  
You may also use the AT&T  
Door Phone Controller with a  
dedicated phone.  
DIP Switch Selections  
To customize the AT&T Door Phone Controller to your specific  
installation and option requirements, you must properly set the  
8 position DIP switch located on the AT&T Door Phone  
CAUTION: Do not connect to the modular jacks on  
the AT&T Door Phone Controller until after the DIP  
switches have been properly set.  
When using the Door Phone Controller with a small business or  
residential telephone equipment (no PBX installed), the DIP

Basic Door Answer Function  
Operation –  
Visitor Presses Door Speaker Button  
When a visitor presses the door speaker push button, the  
AT&T Door Phone Controller will signal the telephone  
equipment inside your home or building to ring, and activate a  
door-bell/chime device (optional). Any additional presses on the  
door speaker push button will be ignored until the option  
selected ring/chime duration has expired (with the exception  
that a confirmation tone will still be sent to the speaker when  
the door button is pressed).  
Answering a Call from the Door Speaker  
The person inside the building can simply answer the ringing  
phone and establish two-way communications with the door  
speaker. To open the door, the person inside the building either  
enters the Door Code on the telephone’s keypad or presses  
the customer provided door-unlock push button. Either of these  
actions will activate the customer provided electric door strike  
plate device.  
Home/Residential  
3-7  
Installation —  
As an alternative response when the telephone or door  
bell/chime is heard, the person inside the building can press  
the door-unlock push button, which will stop the ringing and will  
open the door. This allows the door to be unlatched without the  
use of a phone.  
Calling the Door Speaker from Inside the Building  
To initiate a call to the door, the person within the building  
simply takes the telephone off-hook and hook-flashes the  
telephone within the first 4 seconds. At this point, there will be  
direct two-way communication from within the building to the  
door speaker.  
Telephone Line In Use When Visitor Presses Door  
Speaker Button  
If a visitor presses the door speaker button while an existing  
call is already taking place on the C.O. line, the AT&T Door  
Phone Controller will generate a “door alert” signal to indicate  
Once the push button is  
a visitor needs attention at the entrance. The person inside the  
building can hook-flash the phone and be in direct two-way  
communication to the door speaker. Then normal AT&T Door  
Phone Controller functions can take place. When door phone  
functions have been completed, i.e., door has been remotely  
opened, hook-flashing the phone again within the forced  
disconnect timeout (or pressing 9) will return the line back to  
the original call. This feature operates much like a call-waiting  
function.  
pressed, you can “Hook Flash”  
to the door speaker and then  
back to the original call only  
once, unless the push button is  
pressed again.  
If you forget to hook-flash back  
to the original call, the AT&T  
Door Phone Controller will call  
you back.  
3-8  
Installation — Home/Residential  
Telephone Line In Use With Door When Incoming Call  
Arrives  
If there is a call in progress between the door speaker and a  
person inside the building and a C.O. call comes in, the person  
inside the building (not the door speaker) will hear a call  
waiting tone. The person inside the building can hook-flash the  
phone (or dial 9) and communicate with the incoming caller.  
When the call is complete, the person inside the building hangs  
up the phone or to speak with the person at the door speaker  
again, the person inside the building must hook-flash the phone  
(within 4 seconds after picking up the receiver).

Operation – Basic Door Answer Function  
Visitor Presses Door Speaker Button  
When a visitor presses the door speaker push button, the  
AT&T Door Phone Controller will signal the telephone  
equipment inside your building to ring, and activate an auxiliary  
alert (door-bell/chime) (optional). Any additional presses on the  
door speaker push button will be ignored (with the exception  
that a confirmation tone will still be sent to the speaker when  
the door button is pressed).  
Answering a Call From the Door Speaker  
When a person inside the building hears the telephone ring  
and/or the door bell/chime sound, he can respond by answer-  
ing the ringing phone. At this point, the AT&T Door Phone  
Controller will establish two-way communication with the door  
speaker. To open the door, the person inside the building either  
enters the Door Code on the telephone’s keypad or presses  
the customer provided door-unlock push button. Either of these  
actions will activate the customer provided electric door strike  
plate device.  
As an alternative response to hearing the telephone or door  
bell/chime, the person inside the building can press the door-  
unlock push button which will stop the ringing and will open the  
door. This allows the door to be unlatched without the use of a  
phone.  
Installation - No Dedicated Trunk/Station Port  
6-9  
 
Calling the Door Speaker From Inside the Building  
Your PBX must be capable of  
relaying the hook-flash from the  
station set to the trunk port.  
To initiate a call to the door in the Trunk Saver mode, the  
person within the building simply takes the telephone off-hook,  
accesses the trunk connected to the AT&T Door Phone  
Controller, and hook-flashes the telephone within the first  
5 seconds. At this point, there will be direct two-way  
communication from within the building to the door speaker.  
To initiate a call to the door in the Port Saver mode, the person  
within the building simply takes the telephone off-hook,  
accesses the trunk connected to the AT&T Door Phone  
Controller, and dials “1” within the first 4 seconds. At this point,  
there will be direct two-way communication from within the  
building to the door speaker. (Alternatively, the person may dial  
a “9” within the first 4 seconds after accessing the trunk in  
order to be immediately connected to the C.O. line.)

feature operates much like a call-waiting function.

Installation - No Dedicated Trunk/Station Port  
Telephone Line In Use With Door When a Call Arrives  
If there is a call in progress between the door speaker and a  
station user and a call (C.O.) comes in, the person inside the  
building (not the door speaker) will hear a call waiting tone. The  
station user can hook-flash the phone (or dial 9) and  
communicate with the incoming caller. When the call is  
complete, the station user hangs up the phone. To speak with  
the door phone again, the station user must either hook-flash  
the phone (within 4 seconds of picking up the receiver) if  
installed for Trunk Saver Mode or dial “1” if installed for Port  
Saver Mode.  
Placing a Call Through the C.O. From Inside Building  
To initiate a call through the C.O. in the Trunk Saver Mode, the  
person within the building simply takes the telephone off-hook,  
accesses the trunk connected to the AT&T Door Phone  
controller, and then dials the desired phone number. This is  
normal procedure for placing an outside call.  
To initiate a call through the C.O. in the Port Saver Mode, the  
person within the building simply takes the telephone off-hook,  
then accesses the trunk connected to the AT&T Door Phone  
Controller. At this point the caller will hear a dial tone from the  
Door Phone Controller. Dialing a “9”, or waiting 4 seconds, will  
switch the caller to the C.O. and the regular phone number is  
dialed.

Phone Controller such as bells, horns, lamps, strobes, and  
chimes.  
The WP91683 L1 Power Supply is a plug-in power supply  
capable of providing 48VDC at up to 200 milliamps. The power  
supply operates from a 115/120 volt AC standard single or  
duplex receptacle.  
The AT&T Door Phone, in conjunction with a telephone system,  
provides a means to alert a customer that a doorbell button has  
been pressed. In response the customer can answer and talk  
to the door from a telephone within the customers premises.

energy and if not installed and used in strict accordance with the  
manufacturer’s instructions, may cause interference to radio and  
television reception.  
NOTE: The AT&T Door Phone Controller has been tested and  
found to comply with the limits for a Class B digital device,  
pursuant to Part 15 of the FCC Rules. These limits are designed  
to provide reasonable protection against harmful interference in a  
residential installation. The AT&T Door Phone Controller  
generates, uses and can radiate radio frequency energy and, if  
not installed and used in accordance with the instructions, may  
cause harmful interference to radio communications. However,  
there is no guarantee that interference will not occur in a  
particular installation. If the AT&T Door Phone Controller does  
cause interference to radio or television reception, which can be  
determined by turning the AT&T Door Phone Controller unit off  
and on, the user is encouraged to try to correct the interference  
by one or more of the following measures:  
Reorient or relocate the radio or TV receiving antenna.  
Relocate the unit to increase the separation with respect to the  
radio or TV receiver or vice-versa.  
Plug the unit into a different outlet so that it and the radio or TV  
receiver are on different branch circuits.  
If necessary, the user should consult the dealer or an experienced  
radio/television technician for additional suggestions. The user  
may find the following booklet, “How To Identify and Resolve  
Radio-TV Interference Problems,” helpful. This booklet was  
prepared by the Federal Government Printing Office, Washington,  
DC 20402. Stock order No. 004-000-00345-4.  
This equipment is registered with the Federal Communications  
FCC (PART 68)  
Commission (FCC) in accordance with Part 68 of its Rules. The FCC  
requires that the manufacturer provide you with the following  
information:  
FCC Regulations and Warranty  
F-1  
 
1. Connection and Use with Nationwide Telephone Network  
The FCC requires that you connect your telephone equipment to the  
nationwide telephone network through a modular telephone outlet or  
jack. The modular telephone outlet or jack to which the equipment  
must be connected is a USOC RJ11C.  
If this equipment causes harm to the telephone network, the telephone  
company will notify you in advance that temporary discontinuance of  
service may be required. If advance notice isn’t practical, the  
telephone company will notify the customer as soon as possible. Also,  
you will be advised of your right to file a complaint with the FCC if you  
believe it is necessary.  
The telephone company may make changes in its facilities, equipment,  
operations, or procedures that could affect the operation of the  
equipment. If this happens, the telephone company will provide  
advance notice in order for you to make the necessary modifications in  
order to maintain uninterrupted service.  
If trouble is experienced with this equipment, please contact your  
dealer for repair and(or) warranty information. If the trouble is causing  
harm to the telephone network, the telephone company may request  
you remove the equipment from the network until the problem is  
resolved.  
Registered equipment may not be used on telephone company Coin  
Telephone Lines. Equipment may be used with Party Lines in areas  
where state tariffs permit such connections and when equipment is  
adaptable for such use.  
2. Information You May Need to Supply the Telephone Company  
Upon request of your local telephone company, you are required to  
provide them with the following information:  
A. The lines to which you will connect the telephone equipment.  
B. The FCC registration number and Ringer Equivalence Number  
(REN). Both numbers are listed on the equipment label. The REN is  
useful to determine how many devices you may connect to your  
telephone line and still have them ring when your telephone line is  
called. In most, but not all areas, the sum of all RENs per line should  
be 5 or less. You may want to contact your local telephone company.  
The local telephone company must also be notified upon final  
disconnection of the equipment from the local telephone company  
lines.
