AT&T Digital Announcer™

The AT&T Digital Announcer™ is a telecommunications product
that can record, store, and play back two voice messages in a
telecommunications systems environment. You can use the AT&T
Digital Announcer in any of the following configurations:

■

an AT&T call management system (CMS) for Merlin®,
MERLlN® II, and MERLIN LEGEND™

■

a standard, 2-wire tip/ring telephone circuit

■

a contact activated start application, such as an emergency
announcement over a loudspeaker paging system

The Digital Announcer provides the following features:

■

Up to two Recorded Announcements May Be Stored
and Played to Callers

The Digital Announcer can record and store either one or
two announcements, depending on your needs. For
example, if you want a “day” message and a “night”

1-1

Introduction

message, you can record both messages and manually
activate the appropriate message at the appropriate time of
day.

■

Announcement Recording by Either a Handset or Pre­Recorded Cassette Tape

The Digital Announcer allows you either to manually record
announcements using the handset or record pre-recorded
announcements from a tape cassette recorder. Almost any
cassette tape recorder can be used for this feature.

■

Upgradable Memory for Announcements

The Digital Announcer comes from the factory with a total
message memory of 64 seconds, which can be upgraded to
128, 192, or 256 seconds. This upgrade must be done by
an AT&T- authorized technician.

■

Customizable Announcement Lengths

At any time, you can change how the total message
memory capacity is allocated between the two messages.
For example, if you were using two messages (message 1
for day and message 2 for night) and needed two messages
of equal length, you could split the total message memory
time between message 1 and message 2 equally. However,
if you realized later that you needed a longer message for
the day and a shorter message for the night, you could
allocate 60 or 80% of the total message memory capacity to
message 1. If you need only one long message, you can
allocate the total message memory capacity to message 1
alone.

■

Rechargeable Internal Battery

The Digital Announcer contains a rechargeable, internal
battery that provides sufficient power to store your recorded
announcements for an extended period of time (depending
on the amount of message memory your unit is equipped
with) and maintain full functional and operational ability for a
defined time.

Applying AC Power

To apply AC power, perform the following steps:

1.

2.

As soon as the unit is powered-up, it begins an internal diagnostic
and initialization procedure. The unit performs this procedure only
if it has been disconnected (without power) for longer than three
hours. During this procedure, the Power LED on the front panel
turns on, and the Battery LED starts blinking rapidly. Next, the M1
LED turns on, and the Mode LED turns red and remains on for the
amount of time allocated for message 1. If you allocated any time
for message 2, the M1 LED turns off, the M2 LED turns on, and
then the Mode LED turns red and remains on for the amount of
time allocated for message 2.

Plug the cord from the power supply into the 10 volt AC

connector on the back panel of the unit.

Plug the power supply into a suitable electrical outlet.

NOTE:

An external power surge suppression unit (such as
an AT&T 147A Surge Protector) is strongly
recommended.

After the unit completes the diagnostic and initialization procedure,
the Mode LED turns off, and the M1 LED starts blinking slowly,
signifying that a message has not been recorded yet. The Battery
LED also starts blinking slowly, indicating that it is recharging for a
period of up to 18 hours. The Battery LED remains on when the
battery is fully charged.

If the blinking pattern or the steady on condition of the Battery LED
is interrupted with an extended off cycle, the unit is in an Out of
Service condition. If this condition occurs, refer to Chapter 5.

2-12

Connecting the Unit to the Telephone System

Depending on the type of configuration you want, perform one of
the following steps:

—

If you are using the unit in CMS mode for MERLIN, MERLIN
II, or MERLIN LEGEND, connect the DIN connector cable
from the CMS unit to the CMS port the rear panel of the
unit.

—

If you are using the unit in tip/ring line interface mode,
connect one end of the modular cord supplied to the Line
connector on the rear panel of the unit, and connect the
other end of the modular cord to an RJ11 jack providing
tip/ring from the host telephone system.

—

If you are using the unit with contact activated start
applications, connect one end of the modular cord supplied

with the unit to the Line connector on the rear panel of the
unit, and connect the other end of the modular cord to an
RJ25 jack providing tip/ring from the host telephone system.
Then, add the contact activation signal to the jack so that it
appears at the unit on pins 1 and 6.

Setting the Battery Option Switch

After the unit is powered up, move switch #1 to the “On” position
so the unit starts charging its internal battery, enabling the unit to
store recorded announcements and answer calls (if specified)
during a power failure. The Battery LED blinks slowly, signifying
that the internal battery is charging. This LED continues blinking
slowly for up to 18 hours, at which time the battery is fully charged.
After the battery is fully charged, the Battery LED stops blinking
and remains on.

Upgrading the Message Memory

Upgrading the Message Memory

A new AT&T Digital Announcer is shipped from the factory with 64
seconds of memory for messages. However, at any time, the user
can order memory chips to upgrade the unit’s message memory to
128 seconds, 192 seconds, or 256 seconds. Each upgrade of 64
seconds of memory consists of two memory chips. Therefore, if the
user upgrades his or her system to 192 seconds of message
memory, the upgrade will consist of installing four additional
memory chips (two chips for each 64 second increment of
memory).

When upgrading this unit, refer to Figures 4-1 and 4-2.
