IBM yesterday bowed to the reality that most of its mainframe users have DEC VAXes in their shops as well by taking on board a product called SNS/SNA Gateway from Interlink Computer Sciences Inc of Fremont, California. The SNS/SNA Gateway is claimed to enable complete bi-directional interaction between SNA and DECnet users and resources. It runs on any VM or MVS system and turns the DECnet systems into peer nodes in the IBM SNA network and the IBM hosts into peer nodes in the DECnet network. Native mode CMS and TSO command sets enable IBM access to DECnet nodes connected to the IBM host via the IBM 8232 Local Area Network Channel Station, the IBM 3172 Interconnect Controller or the IEEE 802.3 IBM LAN Adaptor for the 9370. DECnet users access the IBM host and SNA environment through their familiar Digital Command Language. The software is installed only on the IBM host and requires no system modification, it is compatible with all DECnets, it supports distributed databases and applications and up to 256 concurrent users. It makes the IBM applications accessible by DEC terminal users and programmers without the need for retraining and uses standard file and data formats on IBM and DEC. It’s available July 20, but pricing is complex as the software is modular but it’s ty`ically $50,000 to $100,000.
