Introduction
Overview of the

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.

Installing the AT&T Digital Announcer
Materials Required
To install the Digital Announcer properly for tip/ring, System 25
CMS, System 75 CMS, and contact activated start applications,
you need the following items:
■
modular jack (RJ11-type jack for tip/ring applications; RJ25type jack for contact activated start applications)
■
#1 Phillips® screwdriver
■
cross-connect wire (if connecting to a jack)
■
screw (if mounting the unit on a wall). You will not wallmount the unit if you are using it with a CMS application.
To install the Digital Announcer properly for MERLIN, MERLIN II,
or MERLIN LEGEND CMS, you need the following items:
■
the Announcement interface cord provided with the CMS
interface board
■
#1 Phillips screwdriver
Gathering Information
Before installing the Digital Announcer, you must determine the
following information on the planning form in Appendix A.
■
whether the user wants the unit to answer calls and store
the announcements for up to one-half hour during a power
failure. If the user wants the Power Failure Answer option
set to “off ,” the unit will store the recorded announcements
for up to three hours during a power failure, but will not
answer any calls during that time. When the
2-4
Installing the AT&T Digital Announcer
Power Failure Answer option is activated, the unit will
answer calls and store the recorded announcements
between 30 minutes and 3 hours, depending on the number
of calls serviced by the unit during the power outage.
■
the type of configuration in which the unit will be used. The
unit may be used in one of the following configurations:
—
with an AT&T CMS for MERLIN, MERLIN II, or
MERLIN LEGEND
—
with a conventional tip/ring telephone line interface
(including System 25 CMS and System 75 CMS)
—
with a contact activated start application
■
the number of announcements the user wants (either one or
two announcements).
■
the total message memory available in this unit.
■
the length of time the user wants to allocate to each
announcement.
■
the number of rings before the unit answers a call and plays
an announcement. This feature is known as “Ring Count
Delay.” Ring Count Delay is unnecessary if the unit will be
used with CMS or contact activated start applications.
■
whether the user wants the unit to hang on a wall or rest on
a flat surface.
2-5
Installing the AT&T Digital Announcer
Selecting a Site
The AT&T Digital Announcer may be mounted on a wall or placed
on a shelf.
NOTE:
Do not stack items on this unit or place the unit on
top of other equipment.
Certain factors must be considered before installing the Digital
Announcer for the customer. The Digital Announcer operates
reliably in an office environment, but it needs to be located in an
area that meets the following conditions:
■
near a telephone system interface.
■
near a properly-grounded power outlet. Ungrounded
machines may be harmed by static electricity, may fail to
work properly, and can be a safety hazard. Extensive
internal circuit damage can result by connecting the unit to
an ungrounded outlet.
well-ventilated and away from heat sources. Excessive heat
■
and direct sunlight can cause undesirable conditions such
as low-humidity, which can cause static problems.
■
isolated from strong electromagnetic fields produced by
electrical devices (for example, air conditioners, large fans,
large electric motors, radio and television transmitters, and
high-frequency security devices).
■
away from water and excessive humidity.

Setting the Switches
Before powering up the unit, you must set the switches on the rear
panel of the unit.
To set the switches, perform the following steps:
WARNING:
Do not turn the Battery switch ON prior to applying
AC Power to prevent any possible damage to the
internal components of the unit.

2.
Move switch #1 to the “Batt” position to turn off the battery.
Move switch #2 to the “PF ANS” position to turn off the
Power Failure Answer option. If you turn off this option, the
unit ignores incoming calls during a power failure and
retains its announcements for up to three hours.
NOTE:
The position of this switch has no effect if the unit is
used with MERLIN, MERLIN II, or MERLIN LEGEND
CMS or contact activated start applications. When
used with CMS or contact activated start applications,
the unit retains its announcements for up to three
hours, regardless of the setting of switch #2.
NOTE:
The MERLIN, MERLIN II, and MERLIN LEGEND
CMS delay message length on the “set option”
screen of the CMS PC may need to be changed to
