Provides an enhancement to the ping command included in R7.1. This enhancement 
specifies a longer packet to be sent by ping and shows if a router or host has a problem 
fragmenting or integrating transferred packets.
Information and Reports
Recent Change History
Allows the system manager to view or print a history report of the most recent 
administration and maintenance changes on the switch. This report may be used for 
diagnostic or information purposes.
Service Observing
Allows a specified user, such as a supervisor, to observe or monitor another user’s calls. 
A vector directory number call can also be observed. Observers can observe in 
listen-only or listen-and-talk mode. You set up Service Observing to observe a particular 
extension, not all calls to all extensions at a terminal.
NOTE:
Service Observing may be subject to federal, state, or local laws, rules, or 
regulations or require the consent of one or both of the call parties. Familiarize 
yourself and comply with all applicable laws, rules, and regulations before using 
this feature.
Calling Party/Billing Number (CPN/BN)
Allows the system to transmit Calling Party Number/Billing Number (CPN/BN) information 
to an ISDN-PRI trunk group. The CPN is the calling party’s telephone number. BN is the 
calling party’s billing number. The CPN/BN may contain international country codes. It is 
used with an adjunct application.

Call Charge Information
Provides two ways to know the approximate charge for calls made on outgoing trunks:
nAdvice of Charge — For ISDN trunks
Advice of Charge (AOC) collects charge information from the public network for 
each outgoing call. Charge advice is a number representing the cost of a call; it is 
recorded as either a charging or currency unit. 
nPeriodic Pulse Metering — For non-ISDN trunks
Periodic Pulse Metering (PPM) accumulates pulses transmitted from the public 
network at periodic intervals during an outgoing trunk call. At the end of the call, the 
number of pulses collected is the basis for determining charges. 
Call-charge information helps you to account for the cost of outgoing calls without waiting 
for the next bill from your network provider. This is especially important in countries where 
telephone bills are not itemized. You can also use this information to let employees know 
the cost of their phone calls, and so encourage them to help manage the company’s 
telecommunications expenses. 
NOTE:
This feature is not offered by the public network in some countries, including the 
United States.
In addition, the Pass Advice of Charge to BRI endpoints feature will transparently pass 
AOC information that has been received from PRI networks to WCBRI endpoints.
Bulletin Board
Provides a place on the switch where you can post information and receive messages 
from other switch users, including Lucent Technologies personnel. Anyone with 
appropriate permissions can use the bulletin board for everyday messages. In addition, 
Lucent Technologies personnel can leave high-priority messages, which are displayed on 
the first 10 lines of the bulletin board.

73 Information and Reports 
Call Detail Recording (CDR)
Records detailed call information on incoming and outgoing calls for the purpose of call 
accounting and sends this call information to a Call Detail Recording (CDR) output 
device. You can specify the trunk groups and extensions for which you want records to be 
kept as well as the type of information to be recorded. You can keep track of both internal 
and external calls. This application contains a wide variety of administrable options and 
capabilities.
Traffic Reports
Shows measurements in the form of switch-based reports for local or remote access, and 
can be collected for subsequent analysis and reporting by adjuncts and operation support 
systems using the operation support system interface protocol. These reports include:
nCall Coverage reports, which display measurements of the distribution of traffic 
offered to call-coverage groups. Separate reports for all calls and external calls are 
supplied. 
nCoverage Points, which differs based on whether “All Calls” or “External Calls” is 
selected. For each coverage point in the group, the number of calls offered, 
abandoned while at that coverage point, and overflowing to the next coverage point 
are listed.
nProcessor Occupancy report, which provides summary information on how heavily 
the processor is loaded. 
nTraffic Summary report, which provides a performance summary of the DEFINITY 
ECS
nAttendant Position report, which lists the following:
— Attendant usage
— Number of calls answered
— Total time the attendant was available to answer a new call
— Average holding time on calls answered
nSecurity Violations report
nTandem Traffic report, which provides information on facilities that serve tandem 
traffic
nHunt Group Measurements

Announcements
Recorded Announcement
Provides a recorded announcement to a variety of types of calls: calls that cannot be 
completed as dialed, calls that have been in queue for an assigned interval, any calls 
whose destination is an announcement, or incoming calls to a user.
Music-on-Hold Access
Automatically provides music, silence, or tone to a caller. Music lets the caller know that 
the connection is still valid. Many different music options can be administered to 
accommodate different tenants on the DEFINITY ECS. See the Tenant Partitioning 
feature for more information. 
Multimedia Queuing with Voice 
Announcement
When multimedia callers queue for an available member of a hunt group they are able to 
hear an audio announcement.
Class of Service (COS)
Defines whether or not telephone users can access the following features and functions: 
Automatic Callback, Call Forwarding, Data Privacy, Priority Calling, Restrict Call 
Forwarding Off-Net, Call Forward Busy/Don’t Answer, Personal Station Access, Extended 
Forwarding and Busy/Don’t Answer, Trunk-to-Trunk Transfer Restriction Override, 
Off-Hook Alert, Console Permission, or Client Room.

System Management Features 
75 Administration Without Hardware 
Administration Without Hardware
Allows you to administer telephones that are not yet physically present on the system. 
This feature works the same as administration with hardware: when stations are moved, 
user-activated features such as Call Forwarding and Send All Calls are preserved and 
functional. This greatly facilitates the speed of setting up and making changes to the 
telephones on the system.
Terminal Translation Initialization (TTI)
DEFINITY ECS provides Terminal Translation Initialization, a feature that works with 
Administration Without Hardware. Terminal Translation Initialization associates the 
terminal translation data with a specific port location through the entry of a special 
feature-access code, a Terminal Translation Initialization security code, and an extension 
number from a terminal that is connected to a wired 
(but untranslated) jack.
Tenant Partitioning
Allows partitioning of the DEFINITY ECS in order to lease the system’s services and 
features to tenants. This provides attractive new services and revenue for “virtual” 
landlords. It provides the robust features of a large system at affordable rates to small 
business tenants. DEFINITY ECS supports up to 100 partitions and 27 Attendant Groups. 
Multiple Attendant Groups can be assigned to each partition. Stations, hunt groups, and 
other endpoints assigned to a Class of Service can be partitioned. Network routing 
pattern preferences also support the assigned Tenant Partitioning. Tenant Partitioning 
also allows you to assign a unique music source for each tenant partition for customers 
who are put on hold.
See also, ‘‘Music-on-Hold Access’’ on page 74.
Trunk Management
DEFINITY ECS supports a variety of interfaces to voice and data networks. Trunks supply 
links between DEFINITY ECS, the public network, and other switches.

Trunk Group Circuits
Trunks provide the communications links between DEFINITY ECS and other switches, 
including Central Office switches and other premises switches. Trunks that perform the 
same function are grouped together and administered as trunk groups. Trunks interface 
with DEFINITY ECS via port circuit packs. DEFINITY ECS trunk group circuit types 
include the following:
Local Exchange Trunks
Local exchange trunks connect DEFINITY ECS to a Central Office. The following are 
some of the types available:
nCentral Office trunks, which connect DEFINITY ECS to the local Central Office for 
incoming and outgoing calls
nForeign Exchange trunks, which connect DEFINITY ECS to a Central Office other 
than the local one
nWide Area Telecommunications Service (WATS) trunks, which allow you to place 
long-distance outgoing voice-grade calls to telephones in defined service areas.  
The calls are priced according to distance in the service area, length of the call, 
time of day, and the day of the week
n800-service trunks, which let your business pay the charges for inbound 
long-distance calls so that callers can reach you toll-free
nDirect Inward Dialing (DID) trunks, which connect DEFINITY ECS to the local 
Central Office for incoming calls dialed directly to stations without Attendant 
assistance
nDigital Service 1 (DS1)  trunks, which can be used to provide T1 or ISDN Primary 
Rate Interface (PRI) service
Tie Trunks
Tie trunks carry communications between DEFINITY ECS and other switches in a private 
network. Several types of trunks can be used, depending on the type of private network 
you establish.

Auxiliary Trunks
Auxiliary trunks connect devices in auxiliary cabinets with the DEFINITY ECS. Some of 
the features that are supported with this type of trunk are recorded announcements, 
telephone dictation service, malicious call trace, and loudspeaker paging.
Central Office: The location housing telephone switching equipment that provides local 
telephone service and access to toll facilities for long-distance calling.
Advanced Private Line Termination (APLT)
Provides access to and termination from CO (Central Office)-based private networks; 
namely, Common Control Switching Arrangements (CCSA) and Enhanced Private 
Switched Communications Service (EPSCS). APLT trunks are physically the same as 
those used for analog tie trunks, where the trunk signaling is compatible with EPSCS and 
CCSA network switches. The outgoing APLT trunk repeats any number of digits to the 
private network as dialed. APLT trunks can tandem through the PBX from EPSCS 
network only; CCSA networks require an Attendant to complete the call.
Direct Inward/Outward Dialing (DIOD)
Traditionally, CO (Central Office) trunks and DID (Direct Inward Dialing) trunks interface a 
PBX with a Central Office. A CO trunk services outgoing calls and accepts incoming calls 
that are terminated at the Attendant. A DID trunk is used for calls that need to be 
terminated without an Attendant interaction.
The DIOD trunk combines the features of a CO trunk and a DID trunk to provide both 
outgoing and incoming calls with addressing information in both directions.
IP Trunks
IP trunk groups may be defined as a virtual private network’s tie lines between DEFINITY 
ECS systems or ITS-E servers. Each DEFINITY IP Trunk circuit pack provides a basic 
twelve-port package that can be expanded up to a total of 30 ports. The number of ports 
that are defined will correspond to the total number of simultaneous calls transmitted over 
the IP Trunk Interface.   
The benefits of IP Trunk include a reduction in long distance voice and fax expenses, 
facilitating global communications, providing a full function network with data and voice 
convergence and optimizing networks by using the available network resources.

ISDN Trunks
Gives you access to a variety of public and private network services and facilities. The 
ISDN standard consists of layers 1, 2, and 3 of the Open System Interconnect (OSI) 
model. DEFINITY ECS can be connected to an ISDN using standard frame formats: 
Basic Rate Interface (BRI) and the Primary Rate Interface (PRI).
An ISDN provides end-to-end digital connectivity and uses a high-speed interface which 
provides service-independent access to switched services. Through internationally 
accepted standard interfaces, an ISDN provides circuit or packet-switched connectivity 
within a network and can link to other ISDN supported interfaces to provide national and 
international digital connectivity.
Integrated Services Digital Network—(Basic Rate 
Interface (ISDN-BRI)
Enables connection of the system to equipment or endpoints that support an Integrated 
Services Digital Network (ISDN) by using a standard format called 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.
ISDN is a global access standard that uses a layered protocol. It 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 a digital format.
The ISDN-BRI Trunk circuit pack allows DEFINITY ECS 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. The ISDN-BRI Trunk provides the following advantages:
nProvides an inexpensive way to connect to ISDN services provided by the network 
provider
nMeets almost all ETSI Country protocol requirements
nSupports essential (not supplementary) ISDN services
BRI trunks support public-network access outside the U.S. on point-to-midpoint 
connections, with the restriction that DEFINITY ECS must not be configured in a passive 
bus arrangement with other BRI endpoints. ISDN-BRI trunks can be used as inter-PBX tie 
lines using the QSIG peer protocol.

Full ETSI Functionality
The full set of ETSI public-network and private-network ISDN features is officially 
supported. This includes Look-Ahead Interflow, Look-Ahead Routing, and Usage 
Allocation. It also includes all QSIG supplementary services supported through R8: 
nName Identification
nCall Diversion (including rerouting)
nCall Transfer
nPath Replacement
It does not include:
nDCS
nNon-Facility Associated Signaling
nD-Channel Backup
nWideband Signaling
NT Interface on TN556C
DEFINITY ECS supports the NT (network) side of the T interface using the TN556C 
circuit pack. This gives the switch full tie trunk capability using BRI trunks. DEFINITY ECS 
supports leased BRI connections through the public network, with a TN2185 on each end 
of the leased connection. DEFINITY ECS  will not, however, allow customers to 
administer both endpoints and trunks on the same TN556C circuit pack.
Call-by-Call Service Selection
Enables a single ISDN-PRI trunk group to carry calls to a variety of services, rather than 
requiring each trunk group to be dedicated to a specific service. It allows you to set up 
various voice and data services and features for a particular call.
Facility and Non-Facility Associated Signaling
Allows an ISDN-PRI DS1/E1 interface D-channel to carry signaling information for 
B-channels (voice or data). D-Channel Backup can also be administered to increase 
system reliability.
Wideband Switching
Provides the ability to dedicate 2 or more ISDN B-channels or DSO endpoints for 
applications that require large bandwidth. Certain applications, such as video 
conferencing and high-speed data transmission, require extra bandwidth and it becomes
