Intuity Audix Lx Messaging System - Avaya G700 Installation And Upgrades

INTUITY AUDIX LX Messaging System

The process of integrating an INTUITY AUDIX LX system with an Avaya S8300 Media Server involves
a series of tasks to prepare the switch to work with the INTUITY AUDIX LX system.
The procedures for this process are fully documented in INTUITYTM AUDIX
Documentation, 585-313-818. The information is contained in a document with the title INTUITY

AUDIX LX Release 1.0 LAN Integration with S8300 and DEFINITY
ASAI Co-Resident DEFINITY LAN Gateway (DLG)
The DEFINITY LAN Gateway (DLG) is an application that enables communications between TCP/IP
clients and Communication Manager call processing. In more technical terms, the DLG application is
software that both routes Internet work messages from one protocol to another (ISDN to TCP/IP) and
bridges all ASAI message traffic (by way of a TCP/IP tunnel protocol).
The DLG listens for client connections (a specific IP Address) over a well-known TCP port (5678). The
client accesses the DLG's services by connecting to TCP port 5678 at the IP address of the DLG's
Ethernet interface, which can be a MAPD (TN801B), a Processor (TN2314), or a C-LAN (TN799). The
client then exchanges TCP Tunnel Protocol messages with the DLG to request a connection to a specific
CTI link. The DLG authenticates the client based on its administration and then establishes or refuses the
connection. Once a connection is established, the ASAI layer 3 messages are transparently passed
through the DLG (that is, the DLG does not process any message content). Each TCP connection to the
DLG has a one-to-one correspondence with a CTI link.
The DLG application is packaged either externally on a separate circuit pack (the TN801 MAPD circuit
pack) or internally, where it co-resides with Communication Manager. The externally packaged DLG is
referred to as the MAPD DLG, and the internally packaged DLG is referred to as the Co-Resident DLG.
The Co-Resident DLG and the MAPD DLG accomplish the same basic function (ASAI to Ethernet
transport).
The Co-Resident DLG is application software that co-resides with Communication Manager on the
Media Server running Communication Manager. No physical installation or MAPD-specific
administration is required for the Co-Resident DLG. In terms of switch-based connectivity, the Co-
Resident DLG is supported by the following platforms:
•
Communication Manager S8100 Media Server configurations (formerly DEFINITY ONE and
IP600)
•
Avaya S8300 Media Server with Avaya G700 Media Gateway
Administration of the Co-Resident DLG is carried out on the switch using the change ip-services SAT
command. When the service type DLG is specified on the IP Services form, the DLG administration page
displays. The Co-Resident DLG does not rely on ports. Port allocation is not required for administering
the Co-Resident DLG.
For Avaya S8100 Media Server configurations, the Co-Resident DLG cab use the C-LAN (TN799), the
Processor Card (TN2314), or both as its Ethernet interface. For Avaya S8300 Media Server with Avaya
G700 Media Gateway, the Co-Resident DLG relies on the S8300 Media Server for Ethernet connectivity.
