Application Notes (for Compatibility Chart)

6.

7.

8.

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.

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.

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.

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 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.

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)

Terms You Should Know

AuxiliaryAlert

—A door speaker’s push button can activate a

bell/chime within the building.

Cadence —Telephone Ringing cycle, i.e., 2 second ringing,

4 second no ringing.

C.O. line —Central Office telephone line carrier into building.

EKTS (Electronic Key Telephone System) —Small business

telephone communications system.

Ground Start —One method by which a business telephone

system (PBX) signals the telephone company that you have

gone off-hook. Used in most business applications – contact

your telephone company to determine if you have Ground or

Loop Start.

Loop Start —One method of signaling the telephone company

that your telephone has gone off-hook – used for most

residential and communication system applications. Contact

your telephone company to determine if you have Ground or

Loop Start.

PBX (Private Branch Exchange) —Business telephone

system.

Ringdown

—In Station mode, the activation of the door

speaker’s push button will cause the AT&T Door Phone

Controller to dial the number of a predetermined telephone

station number (PBX or EKTS must be installed). When the

telephone is answered, there is direct two-way communication

with the door speaker.

Trunk Port —PBX connection for Central Office or trunk lines.

Station Port —PBX connection for station sets.

Hook-Flash —This causes telephone equipment to go “on

hook” for a duration usually less than a second (not long

enough to be considered as calling for the circuit to be

released.)
