nInterconnects the system with central offices such as AT&T’s 4ESS switch 
(where services such as MEGACOM and Software Defined Network can 
be accessed) and 5ESS
®-2000 switches
nInterconnects the system with private networks by connection with DS1 
facilities
nCan be used with the same Automatic Alternate Routing capabilities as 
normal analog E&M lead tie trunks.
Configuring your system with an alternate voice/data DS1 interface does the fol-
lowing:
nUses out-of-band signaling in which signaling information is multiplexed 
onto one of the 64 kbps digital channels
nPermits end-to-end voice and digital data connections between systems
nDelivers 23 clear 64 kbps digital channels plus one signaling channel 
multiplexed onto a 1.544 Mbps Digital Signal Level 1 line with provisions for 
framing, maintenance, and signaling
nDelivers 8 kbps timing and slip information for a synchronization subsystem
nSupports ground-start and loop-start switch-central office, foreign 
exchange, and Wide Area Telecommunications Service 
(inbound/outbound) trunks, as well as direct inward dial trunks, 
off-premises stations, and dedicated voice/data system connections.
To achieve even greater benefits than those just listed, you can combine the DS1 
interfaces and ISDN-PRI to give you additional capabilities. ISDN-PRI is a 
DS1-compatible direct-connect access service that links the intelligence inherent 
in the network with the intelligence provided by your system.
For example, with ISDN-PRI, the Software-Defined Data Network service may be 
accessed. Software Defined Data Network provides virtual private-line connectiv-
ity, via a switched network, for voice, data, and video applications. Soft-
ware-Defined Data Network services compliment the Software-Defined Network 
voice services.
The system delivers Automatic Restoration capability with Software-Defined Data 
Network, which restores disrupted connections between access end points 
(non-signaling trunk) and data end points (devices that connect the system to 
computers and data communications equipment). This restoration is achieved 
within seconds of a service disruption so that critical data applications can remain 
operational.

ISDN
The system provides a complete set of ISDN features. Demonstrating its role as a 
leader in making ISDN a universal reality, Lucent Technologies makes it possible 
for anyone connected to the system to benefit from ISDN capabilities and 
features.
ISDN eliminates the need for multiple, separate access arrangements for voice, 
data, facsimile, and video services and networks. Using the same pair of wires 
that now carry simple telephone calls, ISDN can deliver voice, data, and video 
services in digital format.
ISDN is a global access standard established by the Consultative Committee for 
International Telephone and Telegraph designed to help you move and manage 
information with unprecedented ease and productivity — anywhere in the world. 
ISDN uses a layered protocol that conforms to layers one, two, and three (physi-
cal, link, and network layers) of the seven-layer Open Systems Interconnect Ref-
erence Model of the International Standards Organization.
The system supports the two major interfaces specified in the ISDN standards — 
PRI and BRI.
nPRI is used for connecting premises equipment to the network, and acts as 
a powerful interface between intelligent equipment such as systems and 
computers.
nBRI is used for connecting telephones, computers, personal computers, 
and other desktop devices to other computer equipment.
The system also supports an optional adjunct that converts ISDN-PRI lines to a 
trunk-side ISDN-BRI. A single PRI is converted to up to eight BRIs plus a propri-
etary 2 Mbps expansion interface. See your Lucent Technologies representative 
for more information about this adjunct.
Both PRI and BRI are based on the same common building blocks — the use of a 
common interface to a transmission path that is divided into channels. Both PRI 
and BRI use two types of channels for communication:
nBearer channels are the communications links in ISDN. They provide 64 
kbps digital communications service for voice, data, video, and other 
information transmission.
nDelta channels, sometimes known as data channels, are the signaling links 
in ISDN. They carry call-control and call-related information, such as caller 
ID, between ISDN endpoints.

PRI, referred to as 23B + D or 30B + D on an E1 interface, uses 23 or 30 64 kbps 
B channels and one 64 kbps D channel. The 23 or 30 B channels can be used 
for 23 or 30 individual voice or data calls. BRI, referred to as 2B + D, uses two 64 
kbps B channels and one 16 kbps D channel. The B channels give the user simul-
taneous voice and data transmission over the same connection. This channel 
architecture allows full and complete use of the 64 kbps B channels from end 
point to end point for information movement managed by signaling messages, 
called Q.931 messages, in the D channel.
To help your business achieve maximum benefits from ISDN and the public net-
work, the following features reside within the ISDN service nodes:
nCall-by-Call Service Selection lets you reach multiple services via the same 
ISDN B channel. Therefore, a channel can be allocated among 
MEGACOM Wide Area Telecommunications Service, MEGACOM 800/888 
Service, and other services on a dynamic basis, eliminating the need for 
dedicating each truck or channel to a specific service.
nAutomatic Number Identification, marketed as Information Forwarding-2 
(INFO-2), is available on MEGACOM 800/888 Service. INFO-2 delivers the 
originating calling party’s billing number to your system.
nStation Identification Number, similar to INFO-2, identifies the calling party 
number behind the system. Station Identification delivers the originating 
caller’s telephone number to the network where it is sent to the terminating 
location.
nUser-to-User Information sends user information from one endpoint to 
another using the D channel. Three forms are available: message 
associated data, sent within Q.931 call control messages during call 
establishment and call clearing; call-associated data, sent during call setup 
on a B channel; and noncall-associated data, sent with no related 
call-setup activity on the B channel. Applications for this feature include 
display of calling party name and number.
The system’s support of ISDN-PRI, ISDN-BRI, and available public network ser-
vices means that you can achieve full end-to-end ISDN connectivity and take 
advantage of ISDN services and features. For example, two systems connected 
by PRI can exchange calling party name and/or number information. The informa-
tion is displayed on the called party’s telephone. In addition, the called party’s ID 
is also displayed at the calling party’s telephone. This lets users identify the 
source of an incoming call before answering. Computer telephone integration 
interfaces can also use the information provided by the network to integrate your 
communications and data-processing systems.

The system also adds the following capabilities to the basic ISDN services, 
depending on local availability of support.
nCall-by-Call Service Selection, in addition to the services provided by this 
feature on the network, allows each trunk in a PRI link from your system to 
the local central office to be designated on a per-call basis as Direct Inward 
Dial, incoming Wide Area Telecommunications Service, outgoing Wide 
Area Telecommunications Service, and so forth. This eliminates the need 
for dedicating each trunk or channel to a specific service, although they can 
still be dedicated, if desired.
nISDN flow control monitors message activity on the Primary Rate Interface 
D channel.
nNon-Facility-Associated Signaling allows a PRI D channel to supply 
signaling for B channels (voice and data) located on PRI interfaces other 
than the one where the D channel is found. As a result, one D channel can 
support call control and signaling for up to 20 Primary Rate Interfaces.
nD Channel backup, when administered, improves reliability in the event of 
a signaling link failure on a Non-Facility-Associated Signaling D channel 
group. A primary D channel provides signaling for the Non-Facility- 
Associated Signaling D channel group (two or more Primary Rate Interface 
facilities). A second D channel, located on a separate Primary Rate 
Interface facility of the same Non-Facility-Associated Signaling D Channel 
group, is designated as a backup. If the primary D channel fails, call-control 
signaling automatically transfers to the backup D channel.
By combining public network services and ISDN features with the system’s ISDN 
and other features, you can differentiate your business from your competitors, 
both in improved customer satisfaction and in greater operating efficiency. The 
result is improved profits and reduced costs. Here is a brief glance at a few of the 
possible ISDN applications:
nDealer locator
nProduct sourcing and fulfillment
nConsumer-to-business and business-to-business data retrieval
nLogging for callback.

IP Trunks
IP trunks allow you to route voice and fax calls over Internet Protocol (IP) 
networks such as the Internet and private intranets, reducing long-distance 
charges and giving you added flexibility in routing traffic between sites. Both the 
originating and destination switches must have the DEFINITY Internet Protocol 
Trunk (DEFINITY IP Trunk) application or Lucent’s Internet Telephony 
Server-Enterprise (ITS-E) Release 1.2. The DEFINITY IP Trunk feature consists 
of the following components:
nAn IP Trunk circuit pack, which contains a Windows NT server
nThe DEFINITY IP Trunk software, which routes telephone calls and faxes 
over the Internet or your company’s intranet
nConfiguration Manager software, which lets you administer the operation 
and performance of DEFINITY IP Trunk service.
Both the IP trunk software and Configuration Manager reside on the Windows NT 
server on the IP Trunk circuit pack. For information about Internet Telephony 
Server-Enterprise, contact your Lucent representative.
NOTE:
DEFINITY BCS and GuestWorks do not support the full IP Solutions feature 
of the DEFINITY ECS, only IP trunks.
Electronic Tandem Network
If your company requires a medium to large network spanning a large geographic 
area, nationwide or even worldwide, Electronic Tandem Network is the answer. An 
Electronic Tandem Network is a wide-area private network that tandems calls 
through one or more systems to route the calls to their destinations.
An Electronic Tandem Network consists of tandem systems, inter-tandem tie 
trunks that interconnect them, access or bypass trunks from tandem systems to 
main systems, and the software and equipment to support call routing over the 
trunking facilities. Different Electronic Tandem Network locations are connected 
via analog or digital tie trunks. For example, a DS1 interface can act as a 
high-speed (1.544 Mbps) digital backbone for voice and data communications 
between Electronic Tandem Network locations.
An Electronic Tandem Network can be configured hierarchically. An Electronic 
Tandem Network can connect individual systems; it can also connect other private 
networks together.
Within an Electronic Tandem Network, each location is identified by a unique pri-
vate network location code, similar to the public network office codes that exist 
within an area code. When accessing the Electronic Tandem Network, a user sim-
ply dials the network office code plus the desired extension number, for a total of 
seven digits.

In an Electronic Tandem Network, the system provides a variety of features on a 
network-wide basis. Here are a few examples:
nUniform Dial Plan — A unique four- or five-digit number assigned to each 
station on the network. Uniform numbering gives each station a unique 
number (location code plus extension) that can be used at any location in 
the Electronic Tandem Network. To access that station, the system 
enhances the standard uniform dial plan with the unrestricted five-digit 
uniform dial plan, which allows up to five digits to be parsed for call routing.
nAutomatic Alternate Conditional Routing — A feature used to control the 
routing of particular calls using conditional routing. For example, you can 
limit the number of communications satellite hops (communications 
satellite links used as trunks) in any end-to-end private network routing 
pattern. Limiting the number of satellite hops may be desirable for 
controlling transmission quality or call delay in both voice and data calls.
nAutomatic Transmission Measurement System — A feature used to 
perform routine and on-demand maintenance tests on facilities in the 
Electronic Tandem Network.
nEnhanced Trunk Signaling and Error Recovery — A feature that improves 
the reliability of Electronic Tandem Network calls by allowing a trunk call to 
be retried on another circuit when signaling failures occur.

Voice Messaging Solutions
Overview
Less than 30 percent of person-to-person business calls reach the intended party 
on the first attempt. Integration with Lucent Technologies voice messaging 
products can help ensure that important calls are not lost.
For nearly a decade, the Lucent Technologies voice messaging systems have 
provided businesses with the voice processing tools to communicate more effi-
ciently and to make time spent on the job more productive. Whether companies 
have ten employees or hundreds, the dilemma of how to do more with less is driv-
ing them toward innovative multimedia processing solutions.
Within an organization, voice messaging is much more than just an answering 
machine. It bypasses idle chatter to promote a communications mode that can be 
much more efficient than two-way calling. Lucent Technologies studies show that 
voice messages average 30 seconds, whereas 2-way calls run much longer and 
are devoted to business only 50 percent of the time.
The Lucent Technologies voice messaging systems available with DEFINITY BCS 
and GuestWorks include the following:
nDEFINITY AUDIX (for non-hospitality offers)
nOctel 100 Messaging (formerly Messaging 2000)
nINTUITY AUDIX
nINTUITY Lodging (for GuestWorks hospitality offers).
NOTE:
Some features and solutions are unavailable in some countries. Please 
contact your local account manager or authorized Lucent Technologies 
representative for further information about which features and solutions are 
available to you.

DEFINITY AUDIX messaging system
While many voice messaging systems require separate equipment and 
connections, the DEFINITY AUDIX Release 4.0 system easily installs directly into 
a DEFINITY BCS cabinet to support advanced multimedia voice messaging 
capabilities without the need for an adjunct processor.
The DEFINITY AUDIX system gives small- to medium-sized businesses full voice 
messaging performance in a streamlined, cost-effective package. The result is 
high-performance voice messaging no matter what your business size. 
Each DEFINITY AUDIX system supports up to 2000 mailboxes and stores up to a 
maximum of 100 hours of recorded messages using a maximum of 12 ports (in 
two-port increments). With each DEFINITY AUDIX package, you also receive a 
complete set of end-user and product-support documentation.
The system includes such features as multiple personal greetings, full-functioned 
automated attendants, outcalling for message notification, and multiple language 
support. The DEFINITY AUDIX system includes both analog (Audio Messaging 
Interchange Specification [AMIS]) and proprietary digital networking software, 
which allows the system to exchange voice messages, subscriber profiles, and 
message status information with other voice messaging systems.
By embedding the voice messaging hardware within the switch, DEFINITY AUDIX 
provides the following advantages:
nBecause it is integrated within the switch, separate review and approval by 
government agencies for compliance with electrical requirements and other 
technical specifications often are not required.
nConnecting to the backplane provides direct access to interfaces such as 
time slots, signaling mechanisms, and power feeds. DEFINITY AUDIX 
uses either display set (DS) integration or X.25 integration. TCP/IP 
integration is not available.
nBypassing analog ports and digital conversions provides a more efficient, 
higher quality call storage process.
nYou can use the system’s maintenance strategy with DEFINITY AUDIX to 
allow remote maintenance by the same team that maintains the switch.
The entire DEFINITY AUDIX system is contained on one circuit pack (two slot 
positions are required in most cases; only one slot position is used if the circuit 
pack is installed in slot 6 of a CMC cabinet). The components mounted on the 
circuit pack include: the central processing unit, the hard disk for real-time 
storage, a magneto-optical disk drive for software updating and backup, the digital 
signal processor complexes that do speech processing, and the time slot 
interfaces for connecting the system to the DEFINITY switch.
