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.
