	   SunLink Channel Gateway available for SPARCserver 600MP

Introduction

SMCC is making available SunConnect's SunLink Channel Gateway version
7.1, which supports the new series of 600/MP SPARCservers. SunConnect
is a Sun Microsystems Incorporated Business. This product allows
customers to have multiprocessor system-to-mainframe connectivity
over high-speed links.	It provides terminal emulation and
bulk file transfer (IBM S/370 Block Multiplexor channel protocols) for
VM or MVS and is also a platform for MVS/NFS and other 3rd-party
applications.

Capabilities

A single IBM channel can address up to 256 different devices. Up to
eight physically separate control units or 16 logically separate
control units or sixteen logically separate units can be attached to a
channel. A Sun server with a SunLink Channel Gateway can simulate one
or more of these control units, up to the maximum allowable number of
the channel. If multiple control untis are emulated simultaneously,
they can be either of the same or different control unit types.

Applications

Applications, called control-unit emulations, run on top of the Channel
Gateway and provide the control-unit specific gateway functionality.
Control-unit emulations can be Sun communication software products,
such as SunLink Local 3270 (see the SunLink 3270 gateway Product
Brief), or user-developed software packages. Users can develop their
own emulations with the SunLink Channel Gateway's application
programmatic interface (API).

Exchange Feature

This feature emulates an IBM Channel-to-Channel Adapter and implements
IBM NJE protocol over the SunLink Channel Gateway to provide bulk
file transfer, job submission, and interactive user messages. These
exchange tools are ideal for Sun/mainframe cross-development.

Hardware Components

The SunLink Channel Gateway product consists of double VME card slot
board assembly, a set of bus and tag interface cables, and Channel
Supervisor software. Together, these components allow the host Sun
processor to connect to an IBM mainframe block multiplexer channel.
