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”

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 Pre-
Recorded 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.
