System Overview 
11 DEFINITY ECS Network Connections 
nATM Circuit Emulation Service (ATM-CES) lets a DEFINITY ECS emulate an 
ISDN-PRI trunk on an ATM facility. ATM-CES maximizes port network capacities by 
consolidating trunking. 
nThe ATM Trunk feature supports telephony and Wide-Area Network (WAN) 
connectivity over ATM networks. ATM-WAN extends the PNC beyond a single ATM 
switch. It allows for use of DEFINITY ECS applications over an ATM infrastructure 
across locations. ATM-WAN consolidates communications traffic, allowing for 
quicker and more efficient transport of voice, data, video, and mixed media 
communications.
Typical Connections

System Overview 
13 International Capabilities 
NOTE:
Actual equipment may appear different than the equipment shown.
International Capabilities
DEFINITY ECS provides features that allow for differences in telecommunication 
standards around the world, allowing you to use the same communications system at 
your various locations in other countries. If you are reading this book, it is likely that the 
system has been type approved in your country. Check with your local distributor for more 
information.
Public Network Call Priority
Provides call retention, forced disconnect, intrusion, mode-of-release control, and re-ring 
to switches on public networks. Different countries frequently refer to these capabilities by 
different names. 
World Class Tone Detection
Enables the DEFINITY ECS to identify and handle different types of call progress tones, 
depending on the system administration. You can use the tone detector and identification 
to display on Data Terminal Dialing and to decide when to send digits on trunk calls 
through Abbreviated Dialing, ARS, AAR, and Data Terminal Dialing.
World Class Tone Generation
Allows you to define call-progress tones. You can select values for frequency and 
cadence. If you do not define a call-progress tone, DEFINITY ECS sends a default sound 
for that call-progress tone that is based on your administered country code. For a very 
few tones, that default may be silence, but for most commonly used tones, that default will 
make a sound.
Administrable Loss Plan
Provides you with the capability to administer the loss or gain applied on calls. This 
capability is necessary because some country regulations change about how much loss 
is allowed on voice calls.

Power
DEFINITY ECS can accept a variety of AC or DC power. The system can operate without 
requiring a power transformer in almost any part of the world.
During a power outage, individual cabinets (Single or Multi-Carrier) will continue to 
function for up to 15 seconds; the Multi-Carrier Cabinet will function for up to 10 minutes 
without power, depending on configuration. Optionally, an Uninterruptible Power Supply 
can protect a DEFINITY ECS system from under or over-voltage conditions, line 
frequency fluctuations, and power blackout of short duration. A battery backup system 
can be used to provide power for up to 8 hours, depending on the type and quantity of 
circuit packs and amount of traffic during the holdover period.
Software 
All DEFINITY ECS systems throughout the world use the same basic software. In 
addition to the basic software, various optional packages can enhance the capabilities of 
the system. Some of the capabilities described in this document require optional 
software. See your Account Representative for more information. The basic software is a 
prerequisite for all the optional packages.

Telephone Features 
15 Telephones 
2 —Telephone Features
Telephones
DEFINITY ECS telephones fall into three basic families—Analog, Digital Communications 
Protocol (DCP), and BRI. These terms describe how each type of telephone 
communicates with the DEFINITY ECS switch. These families of telephones are 
designed to accommodate the types of communications various users require. All 
telephones have touch-tone dialing and the message-waiting lamp for notification of 
messages.
Telephones for the Global Marketplace
With help from our many global customers, Lucent Technologies has developed the 8400, 
9400, 6400 and 6200 series telephones to meet the demand for two-wire telephones in 
the global marketplace. 
8400-Series Telephones
The 8400 digital telephones are versatile two-wire/four-wire Digital Communications 
Protocol (DCP) telephones with new styling that offer new flexibility and cost savings. 
They automatically detect whether they are plugged into a two-wire or four-wire digital line 
circuit card. This is a significant benefit because it provides an easier transition to either a 
two-line or a four-line environment, therefore reducing wiring expenses and installation 
adjustments. It also allows you to save space inside the cabinet by using 24-port two-wire 
boards in place of 16-port four-wire boards.
9400-Series Telephones
The 9400 digital telephones, also known as Europhones, provide inexpensive support for 
two-wire installations, while still providing a European design. Three models of the 9400 
telephones are available in gray and cream white. The 9403, 9410B, 9410D, and 9434 
telephones are similar in design and features to the 8400 series.

6400-Series Telephones
The 2-wire, DCP 6400 digital telephones are similar to the 8400 and 9400 telephones, 
and feature new styling and a pullout instruction card. The 6400 telephones also include 
the following additional features:
nDate and time display.
nA feature button which allows switchhook control of a headset.
nGroup Listen capability, which allows you to use your handset or headset normally 
while others in the room listen in via speakerphone. This 2-way handset, 1-way 
speaker mode allows you to serve as a spokesperson for a group.
nTelephone Self Administration capability, which allows you to program feature 
buttons on the telephone yourself.
6400 Tip/Ring Interface Module
This module provides a two wire analog interface for the 6400 DCP telephones. This will 
allow the operation of an analog adjunct to be independent of the digital telephone’s 
extension for the use of FAX machines or modems without compromising the user’s voice 
extensions.
6200-Series Analog Telephones
The 6210 and 6220 analog telephones are designed to take advantage of the many 
features offered by the DEFINITY ECS. They offer the following features.
nMessage light
nFlash and redial buttons
nHold button and hold light
nHandset volume control
nData jack (for connecting a modem or similar device)
nPersonalized ringing, speakerphone button and light, and programmable dialing 
buttons (6220 only)
IP SoftPhones
IP SoftPhones extend the level of DEFINITY services. They turn a PC or a laptop into an 
advanced telephone. Users can place calls, take calls, and handle multiple calls on their 
PCs. For a discussion of the types of SoftPhones available with IP Solutions for 
DEFINITY ECS, see ‘‘IP SoftPhones’’ on page 58.

Telephone Features 
17 Teleconferencing Products 
Wireless Handsets for X-Station Mobility
X-Station Mobility allows remote users to access switch features. It allows wireless 
telephones remoted over a trunk interface to be controlled by the DEFINITY ECS as if the 
telephones were directly connected to the switch. 
Teleconferencing Products
Quorum A-28 Conference Bridge
The Quorum A-28 Conference Bridge is a microprocessor-controlled analog bridge. It 
allows you to activate a multipoint connection of switched and private-line circuits to 
create a single conversation. You can set up, monitor, and control your own 
teleconferences through your DEFINITY ECS.
The Quorum A-28 Conference Bridge allows you to connect up to 28 different people on 
a single conference call. Or you can set up multiple conferences — up to four 
conferences with seven participants each.
The bridge also provides a lecture mode that you can use for one-way broadcasts. Using 
the Mute feature, participants can be placed in a listen-only mode, allowing one speaker 
to address the rest of the conference.
SoundStation Audioconferencing Systems
Lucent Technologies’s SoundStation and SoundStation EX Audioconferencing Systems 
enable a group of people in a conference room to share their conversation with others 
through a telephone connection. The Soundstation equipment permits natural 
conversation among many people — whether strong or soft, or from a standing or sitting 
position. 
SoundStation
The SoundStation has three microphones and a digitally tuned speaker that provide 
360-degree coverage, whether you use the system in an office or a conference room. It 
connects to an analog telephone line. The built-in keypad includes a mute button and a 
flash key. An additional port allows you to connect the speakerphone to a tape recorder.

19 Telephone Features 
Telephone Features
Handling Incoming Calls
Automatic Hold
Allow Attendants and multi-function telephone users to alternate easily between two or 
more calls. For example, with automatic hold, selection of a second call automatically 
puts the active call (if any) on hold and makes the second call active. This feature can be 
activated on a system-wide basis only. When automatic hold is not activated, the 
selection of the second call drops the first call.
Hold
Allows you to disconnect from a call temporarily, use your telephone for other call 
purposes, and then return to the original call.
Long Hold Recall
Visual and audible warnings are sent to the telephone where a call has been on hold past 
a specified period of time. Both visual and audible warnings are used if the telephone is 
on-hook. If the telephone is off-hook, a priority ring is used. The call is identified as a 
long-held call by the letters hc on the display. This is an optional feature at the system 
level.
Tr a n s f e r
Allows telephone users to transfer trunk or internal calls to other telephones within the 
system without attendant assistance. This feature provides a convenient way to connect a 
party with someone better qualified to handle the call. Single-line telephone users 
momentarily flash the switchhook or press the Recall button, dial the desired extension, 
and hang up. Multi-appearance telephone users press the Transfer button, dial the 
desired extension number, and press the Transfer button again. This is an optional 
feature at the system level.
Pull Transfer
Allows 
either the party who was originally called or the party to whom the held call will be 
transferred to complete the transfer. This is a convenient way to connect a party with 
someone better qualified to handle the call. Attendant assistance is not required and the 
call does not have to be redialed. It interfaces with satellite workstations via TGU/TGE 
trunks and is always available for calls that use TGU/TGE trunks.

20 Telephone Features 
DEFINITY Enterprise Communications Server Release 8.2
Overview  555-233-002  Issue 1
April 2000
Trunk-to-Trunk Transfer
Allows the attendant or telephone user to connect an incoming trunk call to an outgoing 
trunk call. This feature is particularly useful when a caller outside the system calls a user 
or attendant and requests a transfer to another outside number. For example, a worker, 
away on business, can call in and have the call transferred elsewhere. The system 
assures that incoming Central Office trunks without Disconnect Supervision are not 
transferred to outgoing trunks or other incoming Central Office trunks without Disconnect 
Supervision.
Tr a n s f e r  —  O u t g o i n g  Tr u n k
to Outgoing Trunk
Allows a user or attendant to initiate two or more outgoing trunk calls and then transfer 
the trunks together. The transfer operation removes the original user from the connection 
and conferences the outgoing trunks. Alternatively, the controlling party can establish a 
conference call with the outgoing trunks and then drop out of the conference, leaving only 
the outgoing trunks on the conference. This is an optional enhancement to Trunk-to-Trunk 
Transfer and requires careful administration and use. DCS Trunk Turnaround may be a 
safer alternative to this feature.
Tr a n s f e r  U p o n  H a n g - U p
Provides you with the ability to transfer a call by hanging up instead of having to press the 
Transfer button a second time. You would press the Transfer button, dial the number the 
call is being transferred to and then hang up. This is an optional feature at the system 
level. You will still be able to transfer a call by pressing the Transfer button a second time.
Transfer Recall
Returns the unanswered transfer calls back to the person who transferred the call. 
Transfer Recall uses a priority alerting signal, and the display on the telephone shows rt, 
which indicates a returned call from a failed transfer operation.
Abort Transfer
Allows a user to abort a transfer attempt by pressing a non-idle line appearance. The call 
being transferred would be taken off a transfer-type hold and be put on a traditional hold. 
The transfer will also be aborted when you hang up (going on-hook), unless Transfer 
Upon Hang-Up is activated on the switch. This is an optional feature at the system level.
