Avaya 555-233-116 manual How is the DLG application is packaged, Mapd DLG

DEFINITY LAN gateway system

■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.

For more information about the TCP tunnel protocol, see Chapter 7, “TCP Tunnel Protocol,” in the Avaya MultiVantage CallVisor ASAI Protocol Reference, 555-230-221.

How is the DLG application is packaged

The DLG application is packaged either externally on a separate circuit pack (the TN801 MAPD circuit pack), or internally where it co-resides with MultiVantage Software. The externally packaged DLG is referred to as the MAPD DLG. 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 MAPD DLG

As the term MAPD DLG implies, the hardware platform (MAPD) and the software application (DLG) are tightly coupled. The MAPD is essentially a PC that is attached to the switch, and the DLG is an application that is installed on this dedicated PC. The MAPD consists of the following components:

■processor

■disk drive (where the DLG application is installed)

■ethernet

■serial ports

As an application residing externally (in the sense that it is on a separate platform, the TN801 circuit pack), the MAPD DLG must be administered in terms of the MAPD.

Because the MAPD DLG requires installation and has its own administrative interface, it is documented separately. For more information, see the DEFINITY Enterprise Communications Server CallVisor ASAI Applications Over MAPD, 555-230-136.
