Cabletron Systems Inc of Rochester, New Hampshire has revealed more products for end-to-end SNA-local area-wide area network communications and management. Opening the batting is its SNA Network Access Controller Media Interface Module for Ethernet, the SNACMIM-E. According to the company, this is a two- or four-port conversion module for its Multi Media Access Centre hub (CI No 2,533) that converts the SDLC protocol used by SNA devices to the Logical Link Control Protocol used by Token Ring or Ethernet. Next up is the SNA Network Access Controller Media Interface Module SNA to wide area network Concentrator, SNACMIM-SX to its friends, said to provide a consolidated wide area link for SNA device communications. The product apparently concentrates multiple SNA/SDLC, bisync 3270 links and local network-attached SNA/Logical Link Control 2 devices into a single wide area network link, providing either SDLC, X.25 or Frame Relay wide area network communications. Cabletron says it will be available for support of both Token Ring and Ethernet networks.

The 7020MIM is a module intended to provide local to local network communications through an existing SNA backbone. It achieves this by encapsulating local network Internet Protocol and Interet Packet Exchange data in LU6.2, and transporting it through the network as SNA data, says the company. Cabletron claims that the system will lend itself to centralised management of remote local area networks through a Simple Network Management Protocol-based management system using existing SNA lines. Cabletron has also announced version 2.0 of its BlueVision management software. According to the company, the enhancement will enable administrators to manage SNA and local area networks from a central management system as before, but without requiring additional host-based management software. BlueVision 2.0 will be available for the MVS and VM host operating systems. A BlueVision management module – BlueVision InfoMan – was also announced. According to the company, this module, used in conjunction with IBM Corp’s Information manager trouble ticket system, will provide access to the host-based application from the graphical BlueVision user interface. Finally, the company has launched the Advanced Peer-to-Peer Network Node Routing Service. It says this software option provides Network Node topology routing and directory services using Intermediate Session Routing over Token Ring and Frame Relay networks. It is available first for the ETWMIM MMAC-FNB module and the 9T122-24 MMAC-Plus Token Ring concentrator module (CI No 2,549).
