Data General Corp this week expanded its Open Systems Interconnection offerings with five new products under the DG/OSI Communications Architecture banner. The company claims a complete seven-layer implementation of the standard. DG/File Transfer, Access and Management – DG/FTAM – is designed to support transparent file transfer and management between its own minis and systems that meet the FTAM spec; it runs under AOS/VS II, needs DG/OTS and OpneNMS and is $1,500 to $17,400 depending on Eclipse, in the fourth quarter. DG/OSI Applications Platform Interface, DG/OAPI is a C language subroutine library and toolkit that enables value-added resellers and skilled users create Open Systems applications that can communicate across heterogenous networks, under AOS/VS II with DG/OTS, and is $2500 to $29,500, fourth quarter. DG/OSI Transport Services, DG/OTS, is designed to meet the specs of Open System layers two to seven, and a superset of the company’s proprietart Xodiac Transport Services provides routing and end system transport services over local and wide area networks; $900 to $10,440; fourth quarter. The company flags DG/Open Network Management System, DG/OpenNMS, introduced in October 1988, which provides network monitoring and control for DG/OSI Communications Architecture, the Xodiac networking architecture, Personal Computer*Integration and user-developed network applications. And DG/X400, launched in March 1987 implements the Open Systems message handling system for Comprehensive Electronic Office users, enabling exchange of messages and documents with other X400 systems.
