18 Duplication 
DEFINITY Enterprise Communications Server Release 8.2
System Description  555-233-200  Issue 1
April 2000
IP SoftPhones
IP SoftPhones extend the level of DEFINITY services. They turn a PC or a laptop into an 
advanced telephone. You can place calls, take calls and handle multiple calls on your PC. 
There are 4 types of telephones available. They are:
Telecommuter application -- a multifunction station that runs on a PC plus a 
conventional telephone.  Call control is done on the SoftPhone and the voice path 
is on the DCP set. This IP SoftPhone is intended to be used by home workers who 
require PSTN quality audio.  The MedPro board is not used in this application.
Road-warrior application -- a multifunction station that is based entirely on the PC.    
It is used when there is only a single telephone line available to access the IP 
network and the DEFINITY. This IP SoftPhone is intended to use by your traveling 
associates. The MedPro board is used for the road-warrior application.
CentreVu IP Agent -- This SoftPhone is the telecommuter application that has been 
configured to use the CentreVu IP Agent user interface software. It is used as a 
Call Center agent station.
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.
Duplication
Duplication is a strategy to create fully redundant systems. Duplication minimizes single 
failure points that can interrupt call processing. Three system duplication options are 
available:
nStandard reliability--this is the only reliability configuration option available for 
DEFINITY ECS csi model. Will not duplicate Tone-Clock(s), the Control Carrier or 
any inter-PN connectivity.  
nHigh reliability--duplicates the hardware that is associated with the SPE. The 
Control Carrier is duplicated, which provides duplicate SPEs and Tone-Clocks. 
Inter-PN connectivity and EPN Tone-Clocks are not duplicated. The strategy is to 
duplicate items that are associated with the SPE so that a single fault will not cause 
the loss of the SPE. High reliability is available with DEFINITY si and r models.

Overview of DEFINITY ECS R8 
19 Administration 
nCritical reliability--is available with DEFINITY si and r models and requires the full 
duplication of the SPE, inter-PN connectivity and the Tone-Clocks (Category A 
only). 
nATM Network Duplication--requires full duplication of the inter-PN connectivity and 
the Tone-Clocks (Category A only).
As duplication increases, the maximum number of port carriers and port circuit packs per 
cabinet decreases. The information regarding the needed hardware can be found in 
Chapter 3.
Administration
A management terminal connects to the system for administrative purposes. Enter 
commands at the terminal to display administration screens (forms). The forms list data 
and allow you to add, change, and remove system and voice-terminal features. For 
system administration information, consult the 
DEFINITY Enterprise Communications 
Server Release 8 Administrator’s Guide.
Connecting with TCP/IP Networks
LAN Gateway
With the optional J58890MA-1List 2 LAN Gateway circuit-pack assembly installed, 
DEFINITY ECS works with PC/LAN-based communications applications that support the 
CallVisor Adjunct-Switch Application Interface (ASAI) (Category A only). 
C-LAN
TCP/IP Connectivity is provided over Ethernet or Point-to-Point Protocol (PPP) to 
adjuncts such as CMS Call Center and INTUITY AUDIX and for DCS connectivity. The 
C-LAN circuit pack (TN799) provides a bridge from the TDM bus to the packet bus on 
DEFINITY ECS csi.

20 Connecting with ATM Port Networks (Category A only) 
DEFINITY Enterprise Communications Server Release 8.2
System Description  555-233-200  Issue 1
April 2000
Network Control/Packet Interface
Communicates control channel messages between the processor circuit pack and the 
distributed network of port circuit packs on the TDM bus. The NetPkt circuit pack (TN794) 
provides 8 asynchronous data channels that process and route information directly from 
the processor circuit pack to customer-connected equipment.
PassageWay Integrated 
Voice/Data-Workstation Applications
PassageWay applications make the features of the DEFINITY ECS telephone system 
available from the Windows desktop. With PassageWay and the DEFINITY LAN gateway 
implemented, a Call Center application could, for instance, let Agents access all 
job-related resources—the order-processing database, company World Wide Web site, 
phone system, voicemail system, and fax machine—from a single interface on the PC.
Connecting with ATM Port Networks
(Category A only)
ATM-PNC (Category A only)
ATM Port Network Connectivity (ATM-PNC) provides an alternative to either the direct 
connect or Center Stage Switch configurations for connecting the Processor Port 
Network (PPN) to one or more Expansion Port Networks (EPNs). ATM-PNC replaces the 
Center Stage Switch in a DEFINITY R8r network with an Asynchronous Transfer Mode 
(ATM) switch. ATM-PNC is available with all three DEFINITY ECS reliability options—
standard, high, and critical.
ATM-PNC integrates delivery of voice, video, and data via ATM over a common large 
bandwidth LAN, providing reduced infrastructure cost and improved network 
manageability. ATM-PNC uses standards-based open interfaces that can be provisioned 
with either new or existing DEFINITY ECS systems and is ATM-ready for future 
expansion.
