Introduction 1
Overview of CallVisor ASAI Over the
DEFINITY LAN Gateway
CallVisor ASAI over the DEFINITY LAN Gateway is a communications interface
that provides the functionality of the Adjunct/Switch Application Interface (ASAI)
using an Ethernet transport instead of a Basic Rate Interface (BRI) transport. It
is supported by DEFINITY Communications System Generic 3V4, and by
Generic G3V2 and Generic 3V3 (except for Generic 3VS) after a field
maintenance release has been loaded.
The DEFINITY LAN Gateway system (ED-1E546-70) is composed of the system
assembly and a software application. The system assembly is a Multi-Function
Board (TN2208) and an Alarm Board (TN2170) inserted into a DEFINITY carrier.
The software application serves as an ISDN brouter of ASAI messages through
a TCP ‘‘tunnel’’ via 10BaseT Ethernet.
The ASAI-Ethernet transport option can either replace or supplement BRI. For
example, an ASAI-Ethernet link may replace an ASAI-BRI link if more throughput
is desired for the same client application. Or, the ASAI-Ethernet transport option
may be used in addition to the ASAI-BRI transport option if a client application is
being added to the system and the customer does not want to disturb an existing
client application.
Because the DEFINITY LAN Gateway requires its own administrative information
(not found on DEFINITY), it is necessary to administer the system assembly
(TN2170 and TN2208) as well as the DEFINITY switch. For the system
assembly to work with the LAN, the proper TCP/IP parameters must be set up,
and information about the clients who will use the ASAI-Ethernet service must be
administered on the system assembly.
