Computer-Related Calling Features 
51 Alphanumeric Dialing 
Alphanumeric Dialing
Allows you to place data calls by entering an alphanumeric name rather than a long string 
of numbers.
Data Call Setup
Enables the setting up of data calls using a variety of methods, such as: keyboard dialing, 
telephone dialing, Hayes command dialing, permanent switched connections, 
administered connections, automatic calling unit interface, and Hot Line dialing. Data Call 
Setup is provided for both DCP and ISDN-BRI telephones.
Data Hot Line
Provides for automatic placement of a data call when the originator hangs up. Data Hot 
Line may be used for security purposes. This feature offers fast and accurate call 
placement to commonly called data endpoints. Data terminal users who constantly call 
the same number can use Data Hot Line to automatically place the call when they hang 
up the telephone.
Default Dialing
Provides data terminal users who dial a specific number the majority of the time a very 
simple method of dialing that number. This feature enhances Data Terminal (Keyboard) 
Dialing by allowing a data terminal user to place a data call to a preadministered 
destination in several different ways, depending on the type of data module. Data 
Terminal Dialing and Alphanumeric Dialing are unaffected.
Data Privacy
Protects analog data calls from being disturbed by any of the system’s overriding or 
ringing features. Data Privacy is activated when you dial an activation code at the 
beginning of the call.

Data Restriction
Protects analog data calls from being disturbed by any of the system’s overriding or 
ringing features. It is administered at the system level to selected analog and 
multi-appearance telephones and trunk groups.
Administered Connections
Automatically establishes an end-to-end connection between two access or data 
endpoints based on administered attributes. This feature provides capabilities such as 
alarm notification, including an administrable alarm type and threshold; automatic 
restoration of connections established over a Software-Defined Data Network; ISDN-PRI 
trunk group [service may be referred to as ISDN-PRI (AC/AE) Service]; scheduled as well 
as continuous connections; and administrable-retry interval for failed connection 
attempts.
Multimedia Calling
Multimedia calls are initiated with voice and video only. Once a call is established, one of 
the parties may initiate an associated data conference to include all of the parties on the 
call who are capable of supporting data. The data conference is controlled by an adjunct 
device called an Expansion Services Module (ESM).
Multimedia Call Early Answer on
Vectors and Stations
Early Answer is a feature applied to multimedia calls in conjunction with conversion to 
voice. Early Answer:
nAnswers the data call
nEstablishes the multimedia protocol prior to completion of a converted call
nEnsures that a voice path to/from the originator is available when the (voice) call is 
answered 
For an incoming call, Early Answer answers the dynamic service-link calls when the 
destination endpoint answers, unless Early Answer is specified during routing or 
termination processing.

NOTE:
The “destination voice endpoint” might be an outgoing voice trunk if the 
destination voice station is forwarded or covered off-premises. 
Multimedia Call Handling
Multimedia Call Handling (MMCH) enables you to control voice, video, and data 
transmissions using your telephone set. The feature buttons on a multi-function 
DEFINITY telephone enable you to conduct video conferences, and forward, cover, hold, 
or park multimedia calls much as you would a standard voice call.
 You can also share PC 
applications so that you and colleagues can collaborate while working from remote sites. 
See Figure 10.

Computer-Related Calling Features 
55 Multimedia Calling 
Multimedia Call Redirection to MM Endpoint
A dual port multimedia station may be a destination of call redirection features such as 
call coverage, forwarding, and station hunting. The station can receive and accept full 
multimedia calls or data calls converted to multimedia.
Multimedia Data Conferencing (T.120) via 
ESM
The data conference is controlled by an adjunct device called an Expansion Services 
Module (ESM). The Expansion Services Module is used to terminate T.120 protocols 
[including Generalized Conference Call (GCC), a protocol standard for data conference 
control] and provide data conference control and data distribution. The MultiMedia 
Interface circuit pack, TN787, is used to rate adapt T.120 data to/from the ESM. 
Multimedia Hold, Conference, Transfer, and 
Drop
Station users have the ability to activate hold, conference, transfer, or drop on multimedia 
calls. Multimedia endpoints and voice-only stations may participate in the same 
conference.
Multimedia Multiple-Port Network
DEFINITY ECS supports the equivalent of 580 Basic mode complexes operating at 6CCS 
traffic level. All enhanced mode complexes operate with soft-mode service links since the 
use of hard-mode service links reduces capacities. G3si limits are 1/3 to 1/2 of the G3r 
limits, depending on memory limitations and port network limitations. 
Multiple Call Appearances
The dual port multimedia station provides multiple call appearances, each representing a 
multimedia call or a voice call.

56 Multimedia Applications Server Interface 
DEFINITY Enterprise Communications Server Release 8.2
Overview  555-233-002  Issue 1
April 2000
Multimedia Applications Server 
Interface
The Multimedia Applications Server Interface provides a link between the DEFINITY ECS 
and one or more Multimedia Communications eXchange nodes. A Multimedia 
Communications eXchange is a stand-alone multimedia call processor produced by 
Lucent Technologies. This new link to DEFINITY ECS enhances the capabilities of each 
Multimedia Communications eXchange system by enabling it to share some of the 
DEFINITY ECS features. In particular, the interface provides the following advantages:
nCall Detail Recording (CDR)— The capture of call detail records so you can 
analyze the call patterns and usage of multimedia calls just as DEFINITY 
administrators analyze normal calls.
nAutomatic Alternate Routing/Automatic Route Selection (AAR/ARS) — The 
intelligent selection of the most cost-effective routing for calls, based on available 
resources and your carrier preference. The system may select public trunks via 
DEFINITY Multimedia eXchange (MMCX)
nVoice Mail Integration — You can access your DEFINITY or INTUITY AUDIX voice 
messaging system from a Multimedia Communication eXchange (MMCX).
Local Area Network Connectivity 
(LAN)
The DEFINITY LAN Gateway feature lets the DEFINITY system exchange messages 
with PC/LAN-based communications software. The Control LAN (C-LAN) interface 
simplifies connections between adjunct equipment and DEFINITY. It provides TCP/IP 
connectivity over Ethernet or Point-to-Point Protocol connections to applications such as 
CMS Call Center, I
NTUITY AUDIX, and DCS.
IP Solutions
The capabilities and applications of DEFINITY ECS are extended with the introduction of 
IP Solutions. IP Solutions supports audio/voice over a LAN or WAN, and it ensures that 
remote workers have access to communication system features from their PCs.

57 IP Solutions 
NOTE:
To maximize voice quality using IP Solutions, you must consider both your 
hardware and network configurations.  For example, with IP Softphones, you can 
send the audio over traditional circuit switch lines, providing high quality voice, or 
over IP using LAN connections.  When making calls over the LAN, voice quality 
will vary and may be unacceptable if you dont tune your computers and data 
network.  For example, systems without full duplex audio cards and switch 
Ethernet ports are not recommended and will provide poor audio quality.
In addition, IP call capacities currently do not match those of traditional switch 
lines. See Chapter 4 in the 
DEFINITY ECS R8.2 System Description for more 
inofmration on call performance.  
IP Solutions supports two trunk configurations and three types of softphones. It uses a 
new IP Interface circuit pack inside the DEFINITY ECS. This IP Interface is new with 
Release 8. It can operate in either of the following two modes:
nIP Trunk—used for IP trunk connections. This is the default mode for the Release 8 
IP Interface, and this mode makes it compatible with Release 7 systems.
NOTE:
IP Trunk is the default mode for the Release 8 IP Interface only because it may 
also be used to replace the IP Interface in Release 7 systems. In a Release 8 
system, however, the Release 8 IP Interface should be used in MedPro mode.
nMedPro—used for H.323 trunk connections and H.323 voice processing for IP 
softphones. This mode requires the new C-LAN circuit pack.
DEFINITY ECS supports multiple Release 8 IP Interfaces operating in a mixture of these 
two modes or a combination of Release 7 IP Interfaces (operating in the IP Trunk mode) 
and Release 8 IP Interfaces (operating in either mode). However, a Release 7 or 
Release 8 IP Interface operating in IP Trunk mode cannot communicate with a Release 8 
IP Interface operating in MedPro mode.
Trunks
IP Solutions supports the following two types of trunks.
H.323
The Release 8 IP Interface in MedPro mode enables H.323 trunk service using IP 
connectivity between two DEFINITY ECS systems. The H.323 trunk groups can be

configured as DEFINITY-specific tie trunks, generic tie trunks, or direct-inward-dial (DID) 
public trunks. In addition, the H.323 trunks support ISDN features such as QSIG and 
BSR.
IP Trunk
The Release 8 IP Interface in IP Trunk mode allows for operation with existing Release 7 
IP Interface circuit packs. It allows trunk groups to be defined as DS1 tie lines between 
DEFINITY ECS systems over a virtual private network. 
IP SoftPhones
IP Solutions supports the following three SoftPhone applications.
Road-warrior Application
Enables use of the full DEFINITY ECS feature set from temporary remote locations 
anywhere in the world. The road-warrior application consists of two software applications 
running on a PC that is connected to DEFINITY ECS over an IP network. On DEFINITY 
ECS, the road-warrior application requires the C-LAN circuit pack for signaling and the 
Release 8 IP Interface running in MedPro mode for voice processing.
Telecommuter Application
Enables telecommuters to use the full DEFINITY ECS feature set from home. It consists 
of a PC and a telephone with separate connections to DEFINITY ECS. The PC provides 
the signaling path and the user interface for call control. A standard telephone provides a 
high-quality voice path. The telecommuter application requires the C-LAN circuit pack for 
signaling. The telecommuter application does not use the Release 8 IP Interface.
CentreVu IP Agent
Provides a variation of the telecommuter application. CentreVu IP Agent emulates a 
Lucent CallMaster set and provides use of the call end capabilities required for Call 
Center operations from a remote location, such as the agent’s home.
