■
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,
