21 Connecting with ATM Port Networks (Category A only) 
ATM-CES (Category A only)
ATM-CES (Circuit-Emulation Service) lets the DEFINITY ECS emulate an ISDN-PRI 
trunk on an ATM facility. These virtual trunks can serve as integrated access, tandem, or 
tie trunks. ATM-CES trunk emulation maximizes port network capacities by consolidating 
trunking. For example, the CES interface can define up to ten virtual circuits for tie-line 
connectivity, consolidating onto one circuit card network connectivity that usually requires 
multiple circuit packs.
ATM WAN (Category A only)
ATM Wide Area Network (ATM WAN) extends the Port Network Connectivity (PNC) 
beyond a single ATM switch. This allows you to use either a private ATM network, public 
WAN, or a combination of both. Several networked ATM devices can be used as 
effectively as a single ATM switch for inter-port network connectivity. ATM WAN is 
supported by the Multiple Location feature, where port network cabinets can be 
administered as separate locations; however, it is not required. You can use multiple ATM 
switches without multiple locations administered.

IP Solutions (Category A only)
DEFINITY ECS IP Solutions brings together the flexibility of IP networks with the richness 
of voice communication. It allows investment protection and optimization in IP, ATM, and 
PSTN networks. Full applications, features, and management capabilities are carried into 
the IP environment. Remote workers have full access to communication system features 
from their PCs. Figure 1 shows the trunk and line connections available with IP Solutions.
NOTE:
Voice quality can and will vary based on LAN conditions, which are extraneous to 
IP Solutions.

Overview of DEFINITY ECS R8 
23 IP Solutions (Category A only) 
As shown in Figure 1, DEFINITY ECS IP Solutions supports IP connectivity for two types 
of trunks and three types of IP Softphones.
DEFINITY ECS IP Solutions is implemented using the TN802/TN802B IP Interface 
assembly, which is a Windows NT server that resides on the IP-Interface circuit pack 
inside the DEFINITY ECS. The TN802B IP Interface, introduced in Release 8, operates in 
either the IP Trunk mode (for IP trunk connections) or in the MedPro mode (for H.323 
trunk connections and H.323 voice processing for IP softphones). The TN802 
IP-Interface, introduced in Release 7, operates only in the IP Trunk mode. The TN802B 
defaults to IP Trunk mode and is backward compatible with Release 7. The MedPro 
mode requires the new TN799B C-LAN circuit pack.
With Release 7 software, or with Release 8 software configured as Release 7 (that is, R8 
used as a bugfix for R7), the TN802B can be used only in the IP Trunk mode. With 
Release 8 software, the TN802B can be used in either mode but each TN802B can 
operate in just one of the two modes at a time; that is, all trunks supported by the same 
TN802B must all be operating in the same mode. DEFINITY ECS supports multiple 
TN802Bs operating in a mixture of the two modes or a combination of TN802s (operating 
in the IP Trunk mode) and TN802Bs (operating in either mode).
The IP Trunk and MedPro modes are not interoperable; that is, the TN802B in MedPro 
mode cannot communicate with another TN802B in IP Trunk mode or with a TN802.
Trunks
DEFINITY ECS IP Solutions supports two trunk configurations:
nH.323 Trunk
nIP Trunk
H.323 Trunk
MedPro mode supports the H.323 version 2 protocol and interoperates with H.323 
version 2 endpoints, including stations, trunks, and gateways. The TN802B IP Interface in 
Medpro mode enables H.323 trunk service using IP connectivity between two DEFINITY 
ECS systems. H.323 trunk groups can be configured as DEFINITY-specific tie trunks 
supporting ISDN trunk features such as DCS+ and QSIG, or as generic tie trunks 
permitting interconnection with other vendors’ H.323 v2-compliant switches, or as 
direct-inward-dial (DID) type of “public” trunks providing access to the switch for 
unregistered users. TheTN802B in MedPro mode requires the TN799B for signaling.

IP Trunk
In Release 8, the IP Trunk mode will typically be chosen for interoperability with existing 
TN802 (as opposed to the TN802B) IP Interface circuit packs.
The IP Trunk mode allows trunk groups to be defined as DS1 tie lines between DEFINITY 
ECS systems over a virtual private network (VPN). Each IP Interface circuit pack in IP 
Trunk mode provides a basic twelve-port package that can be expanded up to a total of 
30 ports.
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.
Each TN802 or TN802B in IP Trunk mode requires a connection to a modem and an 
incoming line for Lucent remote access. The TN802 (but not the TN802B in IP Trunk 
mode) also requires direct access to the NT server on the TN802 hard disk using 
pcANYWHERE, version 8 or later. A TN802B in the IP Trunk mode does not require the 
TN799B. 
IP Softphones
DEFINITY IP Softphones operate on a PC equipped with Microsoft Windows 95/98/NT 
and with TCP/IP connectivity to DEFINITY ECS.
DEFINITY IP Solutions supports three IP Softphone configurations:
nRoad-warrior application (voice over IP)
nTelecommuter application (dual-connection)
nCentreVu IP Agent (dual-connection)
nNative H.323

Road-warrior application
The road-warrior application of the DEFINITY IP Softphone enables travellers to use the 
full DEFINITY ECS feature set from temporary remote locations anywhere in the world 
such as a hotel room. The road-warrior application consists of two software applications 
running on a PC that is connected to DEFINITY ECS over an IP network. The single 
network connection between the PC and DEFINITY ECS carries two channels, one for 
the signaling path and one for the voice path. DEFINITY IP Softphone software handles 
the call signaling and an H.323 V2-compliant audio application, such as Microsoft 
NetMeeting, handles the voice communications. The user places and receives calls via 
the IP Softphone interface on the PC and uses a headset connected to the PC (or the 
PC’s microphone and speakers) to speak and listen.
With the road-warrior application, NetMeeting has been configured to run in the 
background and use only the audio portion of the applications. The data collaboration 
feature of NetMeeting can be used as a stand-alone application but it is disabled during 
an IP Softphone session.
On DEFINITY ECS, the road-warrior application of the IP Softphone requires the TN799B 
(C-LAN) for signaling and the TN802B IP Interface circuit pack assembly running in 
MedPro mode for voice processing. Each VOIP Softphone requires the administration of 
two stations — an H.323 station and one of the types of DCP station.
Telecommuter application
The telecommuter application of the DEFINITY IP Softphone 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 is connected to DEFINITY ECS 
over an IP network to provide the signaling path. The PC runs the DEFINITY IP 
Softphone software to provide the user interface for call control. A standard telephone is 
connected to DEFINITY ECS over the public switched telephone network (PSTN) to 
provide a high-quality voice path. The user places and receives calls via the IP Softphone 
interface on the PC and uses the telephone handset to speak and listen.
On DEFINITY ECS, the telecommuter application of the IP Softphone requires the 
TN799B (C-LAN) for signaling. The TN802B IP Interface is not used for the telecommuter 
application. Each instance of the telecommuter application requires the administration of 
two stations — an IP Softphone station and one of the types of DCP station.

CentreVu IP Agent
The DEFINITY CentreVu IP Agent is a variation of the telecommuter application. The 
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.
Native H.323
This is an IP-connected softphone running off-the-shelf H.323 software. It operates as a 
single-line phone with limited features, which are activated by Feature Access Codes.
International Requirements
The DEFINITY system complies with the regulations of many countries and supports a 
wide range of languages, including user-defined languages. These are a few examples of 
the country-specific features that are available:
