Computer Telephony Integration (CTI) is the linking of telephone communication systems to personal 
computers, which can increase productivity and customer satisfaction through the exchange of information 
between the PC and the telephone. CTI applications integrate data processing, data communications, and voice 
communications.

DEFINITY ONE supports the following types of CTI applications. 

Server-based solutions that require the Avaya CentreVu Telephony server, the co-
resident DEFINITY LAN Gateway (DLG) function (which resides on the 
DEFINITY ONE Processor Board TN795) and connectivity to DLG via the 
TN795 Processor Board, or optionally via the TN799 C-LAN board.

DEFINITY IP Softphone, enables users to control telephone calls (both incoming 
and outgoing) directly from a personal computer. 

www.messenger provides quick and easy access to your telephone, fax, and text 
messages through your web browser.

DEFINITY ONE supports third-party CTI applications via ASAI and TCP/IP links. 
These CTI links are supported on DEFINITY ONE via the DEFINITY LAN Gateway 
functionality which is co-resident on the DEFINITY ONE Processor board (TN795). 

The co-resident DEFINITY LAN Gateway supports one ASAI link. The ASAI link is 
normally routed from the CTI Server (an external Windows NT or Windows 2000 
server) running CentreVu and the TN795 Processor card via TCP/IP. 

For security reasons, the link may be routed from the CTI Server to a C-LAN board 
(TN799) in the DEFINITY ONE system. The C-LAN board requires use of one 
additional slot in the DEFINITY ONE cabinet. The maximum message rate over the 
ASAI link is 100 messages per second full duplex, regardless of whether the link is 
going directly to the TN795 Processor board or being routed via a TN799 C-LAN 
board.

ASAI links from CentreVu CT to DEFINITY ONE via the TN80153 MAPD board 
are not supported.
