Integrated Services 
Digital Network 
(ISDN)
DEFINITY ProLogix Solutions provides complete ISDN support for up to 500 
stations (600 ports). Demonstrating its role as a leader in making ISDN a universal 
reality, Lucent Technologies makes it possible for anyone connected to DEFINITY 
ProLogix Solutions 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 (physical, 
link, and network layers) of the 7-layer Open Systems Interconnect Reference Model 
of the International Standards Organization.
DEFINITY ProLogix Solutions supports the ISDN Primary Rate Interface, which is 
used for connecting premises equipment such as switches to the network and acts as a 
powerful interface between intelligent equipment such as switches and computers. In 
the U.S., DEFINITY ProLogix Solutions supports line-side or trunk-side ISDN-BRI.

Integrated Services Digital Network - Basic Rate Interface (ISDN-BRI)DEFINITY ProLogix Solutions can connect to equipment or endpoints that support 
an Integrated Services Digital Network (ISDN) by using the Basic Rate Interface 
(BRI). This feature is a 192-Kbps interface that carries two 64-Kbps B-channels and 
one 16-Kbps D-channel.
The ISDN-BRI Trunk circuit pack enables DEFINITY ProLogix Solutions to support 
the T interface and the S/T interface as defined by ISDN standards (ITU-T 
recommendation I.411). The circuit pack provides eight ports to the network and 
supports two B channels and one D channel. ISDN-BRI Trunk provides the 
following advantages:•
Provides an inexpensive way to connect to ISDN services provided by the 
network provider
•
Meets almost all ETSI Country protocol requirements
•
Supports essential (not supplementary) ISDN services
DEFINITY ProLogix Solutions Release 2.0 supports the NT (network) side of the T 
interface using the TN556C circuit pack. This give DEFINITY ProLogix Solutions 
full tie trunk capability using BRI trunks. DEFINITY ProLogix Solutions Release 
2.0 supports leased BRI connections through the public network, with a TN2185 on 
each end of the leased connection. However, DEFINITY ProLogix Solutions Release 
2.0 does not allow you to administer both endpoints and trunks on the same TN556C 
circuit pack. 
						

							10  Centralized Attendant ServiceDEFINITY ProLogix Solutions Release 2 Overview 
555-235-100 Issue 2 June 1999 10-22
Centralized Attendant ServiceDEFINITY ProLogix Solutions owners who have more than one switch location can benefit greatly by using 
the Centralized Attendant Service feature. Centralized Attendant Service reduces the number of required 
attendants, and, in most cases, all those attendants can be located at one of the switch locations, called 
“main.” Switches at the other locations, called “branches,” redirect their calls to the Centralized Attendant 
Service main. Thus, a company can have a centralized attendant group at the headquarters office and can 
handle calls from there for the branch offices.
All locations in a Centralized Attendant Service arrangement have a listed directory number. Calls to a 
branch listed directory number terminate at the main location, even if the branch location has an attendant. 
These listed directory number calls are routed to the centralized attendant group over trunk circuits called 
release-link trunks. These release-link trunks are used only for centralized attendant calls and signaling.
After a call is processed by the centralized attendant, it is extended back to the branch location. The release-
link trunk is then dropped and made available for other calls to the centralized attendant.
If a DEFINITY ProLogix Solutions is a node within a Distributed Communication System and Centralized 
Attendant Service is provided, a centralized attendant can do the following:
•
control access to specific trunks at other nodes
•
directly access to specific trunks at another location
•
place test calls to telephones and trunk groups at other nodes
•
receive a visual warning that all trunks in a remote trunk group are busy or that 
the number of busy trunks in a remote group has reached a specified level
This feature ensures that all calls directed to an attendant at your company are handled efficiently. 
						

							10 Main/Satellite/TributaryDEFINITY ProLogix Solutions Release 2 Overview 
555-235-100 Issue 2 June 1999 10-23
Main/Satellite/TributaryIf you have modest network requirements, a main/satellite/tributary configuration is an attractive possibility 
for private networking. In this configuration, one DEFINITY ProLogix Solutions location is the main, and 
remote switches are satellites or tributaries. Attendant positions and public network facilities are usually 
concentrated at the main.
All calls to or from a satellite pass through the switch at the main. The system appears to be a single switch 
with one listed directory number. A uniform dial plan provides a common 4-digit or 5-digit dial plan for a 
main/satellite configuration.
A tributary is similar to a satellite, but it has one or more attendant positions and its own listed directory 
number. Calls to its listed directory number go directly to the tributary.
The switches in a main/satellite/tributary network are connected by tie trunks. Trunks and switching 
facilities can be added as requirements grow.
An important DEFINITY ProLogix Solutions’ networking feature is Main/Satellite Extended Trunk Access. 
Extended Trunk Access allows dialed digits that are undefined at a satellite or tributary switch to be routed 
over a trunk group to a main switch for interpretation. This flexibility means changes to the network 
numbering plan do not have to be propagated to all switches. Extended Trunk Access improves your control 
and reduces administration costs by making trunk networks considerably easier to maintain. 
						

							10  Electronic Tandem NetworkDEFINITY ProLogix Solutions Release 2 Overview 
555-235-100 Issue 2 June 1999 10-24
Electronic Tandem NetworkIf 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 switches to route the calls to their destinations.
An Electronic Tandem Network consists of tandem switches, inter-tandem tie trunks that interconnect them, 
access or bypass trunks from tandem switches to main switches, 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 switches; it can also connect other private networks (such as Main/Satellite/Tributary 
networks) together.
Within an Electronic Tandem Network, each location is identified by a unique private network location 
code, similar to the public network office codes that exist within an area code. When accessing the 
Electronic Tandem Network, a user dials a feature access code for the Automatic Alternate Routing feature 
plus the 7-digit number, for a total of eight digits.
