Features and Compatibility
Feature Overview
Chapter 1 — Features and Compatibility
With the high-quality voice messaging system DEFINITY AUDIX system
Release 4.0, customers don’t have to answers telephones, and they can
exchange messages at times when it is unnecessary or inconvenient to
talk in person. The DE F INITY AUDIX system saves valuable office space
and simplifies system administration by residing inside the customer’s
switch and sharing a single administration terminal. These features, as
well as new enhancements for reliability, make the DEFINITY AUDIX
system Release 4.0 a desirable voice messaging solution for customers
worldwide.
Feature Overview
The DEFINITY AUDIX system offers many features for customer
organizations, individual subscribers, and DEFINITY AUDIX system
administrators to help streamline information exchange among
employees.

improve voice messaging efficiency in customer organizations:
■ Support up to 2000 local subscribers and 100,000 remote
subscribers
■ Store up to 100 hours of voice messages
■ Exchange messages with other voice messaging systems via
Digital Networking and Audio Messaging Interchange
Specification (AMIS) Analog Networking
■ Post greetings and instructions in up to 9 languages from 30
available announcement sets, including a set for teletypewriters
(TTYs)
■ Answer calls with different messages according to the time of day
and holidays
■ Broadcast messages to large groups of subscribers
simultaneously

Savings from A Smaller System
The space the DEFINTY AUDIX system Release 4.0 requires from the
customer’s switch has decreased from previous releases of the system
by 60%. The system now only requires two universal port slots in the
customer’s DEFINITY switch or one slot in a Compact Modular Cabinet
(CMC),
For smaller switches, such as the CMC, a voice messaging system that
only takes one or two slots can make expanding the customer’s
telecommunications capacity much more efficient in the long run. With a
two-slot voice messaging system, customers can further expand their
telecommunications capacities—adding voice ports or local area
network (LAN) features, for example—before they must invest in switch
upgrades.

Features for the Subscriber
Subscribers can perform many tasks with the DEFINITY AUDIX system
that make communication faster, easier, and more convenient:
■ Store incoming and outgoing messages in a voice mailbox
■ Use a streamlined voice menu to speed through complex
transactions
■ Post multiple personal greetings on the system, which
subscribers can change according to their availability
■ Compose spoken messages with Voice Mail, which they can
send to one or more other subscribers on the DEFINITY AUDIX
system
■ Send messages to many recipients at once using mailing lists
■ Address voice mail messages by typing recipients’ names, rather
than their extensions, on their telephone keypads
■ Advance or rewind messages as th ey listen
■ Receive visual notification of new messages with message
waiting indicators (MWIs)—lights or display screens on
subscribers’ telephones that indicate new messages

Native and Non-native Mode
The DEFINITY AUDIX system can operate with almost any Lucent
Technologies switch release. However, only DEFINITY switch releases
7.1 and later will recognize the DEF INITY AUDIX system’s TN568 circuit
pack.
1-5
The circuitry for the DEFINITY AUDIX system is assigned a vintage
number that communicates the system’s function to the switch. The
vintage number for DEFINITY AUDIX system Release 4.0 is 48. Switch
releases 7.1 and later re cognize this number as belonging to the
DEFINITY AUDIX system’s TN568 circuit pack. Switch releases earlier
than 7.1recognize vintage number 48 as belonging to one of two digital
port circuit packs:
■ TN754, an 8-port digital circuit pack
■ TN2181, a 16-port digital circuit pack

When the DEFINTY AUDIX system operates in a switch that recognizes
its vintage number as a TN568, the system is operating in

When the DEFINITY AUDIX system operates in a switch that recognizes
the system as a TN754 or TN2181 circuit pack, it is operating in

the DEFINITY AUDIX system will only support 12 voice ports.
Administering the DEF INITY AUDIX system’s voice ports for
TN2181 emulation requires the use of special procedures. For

5. Even though the DEF INITY AUDIX system is emulating a circuit
pack other than the TN568, the digital port circuit pack the system
is emulating will still register a vintage number 48. This vintage
number is unique to DEF INIT Y AUDIX system R elease 4.0. See the
system description for the customer’s switch for more information
about accessing circuit packs’ vintage numbers.

Operating in non-native mode does not affect subscribers’ or outside
callers’ use of the system. System administrators, however, should be
aware that messages from the switch, such as alarms, that refer to a
TN754 or a TN2181 circuit pack the system is emulating may actually
refer to the DEFINITY AUDIX system.
NOTE:
Lucent Technologies strongly recommends that the DEFINITY
AUDIX system emulates a TN2181 digital port circuit pack in
switch versions 2 and later. A TN2181 emulation supports a
maximum of 12 voice ports, while a TN754 emulation only
supports a maximum of 8 voice ports. If the DEFINITY AUDIX
system emulates a TN2181 circuit pack, system expansion may be
easier. Switch versions earlier than 2 do not support TN2181
circuit pack emulation.

TN568 Circuit Pack
TN568 Circuit Pack
The TN568 circuit pack holds the systems main circuitry and performs
system’s main processing functions, including message routing,
self-diagnosis, and Alarm Origination.
Port Board Emulation
The TN568 holds the system’s voice ports. These voice ports
correspond to the voice ports on a TN754 or TN2181 circuit pack.
DEFINITY switch releases 7.1 and later recognize the TN568 circuit
pack. However, the system’s voice ports interact with the switch like the
voice ports on a TN754 or TN2181 circuit pack regardless of whether the
system is operating in native or non-native mode. For more information
about digital port emulation, see Chapter 1.
Flashware
The TN568 circuit pack uses
boot the system and programs specific to the TN568. Flashware are
programs that reside on flash programmable read-only memory
(FPROMs). FPROMs are hardware that reside on the TN568 and are
protected from accidental erases or rewrites. Copies of all the active
flashware programs are also stored on the hard disk.

2-2
If the customer installs software upgrades or fixes, the new program is
transferred from a MO disk to the hard disk. When the system reboots,
the new program automatically transfers from the hard disk to the
FPROMs and replaces the existing flashware.
Hard Disk Drive
The hard disk drive stores the system’s AUDIX software, subscriber
information and voice messages.
Voice messages that customers may store on the system include voice
mail, personal greetings, automated attendants, and announcement
sets—the sets of automated, verbal instructions that compose the
system’s user interface.
The hard disk drive provides up to 100 hours of voice storage. The
system comes with a minimum of 10 hours of voice storage. Customers
can purchase additional voice storage in five-hour blocks.

Software
AUDIX software allows the DEFINITY AUDIX system to communicate
with the switch through a telephone-like interface. This type of operation
is called set-type emulation. The commands that subscribers and the
switch use to access the system’s software correspond to the interface
on a digital telephone, or set.
The digital set the system emulates depends on whether the system is
operating in native or non-native mode. In switch releases earlier than
7.1, the DEF INITY AUDIX system emulates a 7405D digital telephone. In
switch releases 7.1 and later, the system communicates with the switch
using an ADX16D set-type interface, through which the switch can
recognize the system’s AUDIX software.

Networking
Because of its telephone-like interface, the system can send and receive
messages from other voice messaging systems as a telephone can.
AUDIX software helps the system to communicate efficiently with other
AUDIX systems.
2-3
The DEFINITY AUDIX system has two networking options that use these
capabilities for message exchange:
■ AMIS Analog Networking
■ Digital Networking
AMIS Analog Networking
AMIS is a standard protocol among voice messaging systems. AMIS
Analog Networking uses the Message Delivery feature to send
messages to subscribers on other voice messaging systems that use
the AMIS protocol.
AMIS Analog Networking sends a message through the system’s voice
ports much like a telephone call. The recipient’s voice mail system
receives the message as it would receive any other voice message and
stores it in the recipient’s voice mailbox. Other voice messaging systems
can send messages to the DEFINITY AUDIX system in the same way.
Digital Networking
Digital Networking is an efficient way for DEFINITY AUDIX, AUDIX R1,
NTUITY, and Interchange systems to communicate with each other
I
without using the systems’ voice ports. The DE F INIT Y AUDIX system has
one Digital Networking port that can be dedicated solely to Digital

Networking features. In its maximum configuration, the DE F INITY AUDIX
system can connect through this Digital Networking channel to up to 100
remote systems, or
nodes
.2
Digital Networking offers several advantages over AMIS Analog
Networking:
■ Digital Networking is more secure than AMIS Analog Networking.
■ Digital Networking uses Lucent Technologies’ Digital
Communications Protocol (DCP) to send subscriber profiles and
message status information along with messages, while AMIS
does not send this information.
■ Digital Networking messages have higher voice quality than
AMIS messages because Digital Networking uses CELP
encod ing .
There is one important consideration, however, for customers who want
to use Digital Networking. If customers use Digital Networking, the
DEFINITY AUDIX system will have a maximum of 8 voice ports, rather
than 12. Tab le 2- 1
shows the maximum number of voice ports the
DEFINTIY AUDIX system can have with and without Digital Networking.

High-speed Digital Networking Connections
The DEFINTIY AUDIX system offers three types of Digital Networking
configurations: DCP Mode 1, DCP Mode 2, and DCP Mode 3.
DCP Mode 1 and DCP Mode 3 connections are high-speed Digital
Networking connections. DCP Mode 1 and DCP Mode 3 connections
require high-speed facilities to operate, but these connections offer
advantages where there is heavy voice messaging traffic among
customer sites. These high-speed Digital Networking connections can
accommodate the maximum numbers of local subscribers (2000) and
remote subscribers (100,000) the system allows.

DCP Mode 2 is a low-speed (9.6 Kbps) Digital Networking connection.
DCP Mode 2 requires external hardware to translate digital
transmissions to analog, but it works with most DEFINITY switch
configurations.
3. The DEFINITY AUDIX system uses EIA RS-232 Asynchronous
protocol to communicate with other AUDIX systems in a DCP
Mode 2 connection. Some documentation for Lucent Technologies
voice messaging systems may refer to low-speed Digital
Networking connections as RS-232 connections.

In a DCP Mode 2 connection, the DEF INIT Y AUDIX system connects to a
DCP port on a TN754 circuit pack. It then connects to an analog port in
the switch’s analog trunk group via a data module and a modem.
Customers can use this connection with any DEFINITY or System 75
switch release. Figure 2-3
