Barr / RJE 3770

BARR / RJE communicates with the mainframe by emulating an IBM 3770, a device that uses the standard communications protocol for batch transmission in an IBM SNA environment, and supporting SNA connections to mainframe job entry systems. BARR / RJE serves as an input source that accepts mainframe jobs for further processing and connects to the mainframe in a variety of ways, including 802.2 LLC2, SDLC, and MS/LUA connections. There are no pre-determined limits to the number of network-attached printers that can be supported by BARR / RJE.

This product enables our Mainframe Connectivity application.

BARR / RJE is designed to facilitate migration to the Windows environment for organizations using the BARR / RJE DOS product. Users of the BARR / RJE DOS product can upgrade to this Windows-based solution without making any changes to software on the host. A well thought-out host connectivity and document management strategy also helps to prepare the groundwork for advanced corporate systems, such as enterprise reporting and application integration software.

Connects in multiple ways:

• IP via the Enterprise Extender

• DLSw via connections to your mainframe through special routers that encapsulate SNA protocols within a TCP/IP packet

• 802.2 LLC2 across token ring or Ethernet to host

• SDLC connections (at up to 2.048 Mbps) with V.35, X.21, RS530, RS449, or V.24/RS232 cable

• SNA gateways such as Microsoft HIS, Microsoft SNA Server, or Microsoft SNA Workstation. SNA gateway connects to the mainframe through DLC, SDLC, or CHANNEL (Bus & Tag or ESCON). BARR/NJE connects to the SNA gateway via TCP/IP, IPX/SPX, or NetBEUI protocols

		Features and Benefits

Requirements

• Barr Enterprise Print Server

• Enterprise Extender for IP connections

• BARR/SYNC for SDLC connections

You need one of the following packages only if you are using the MS/LUA link type with BARR / RJE:

• Microsoft Host Integration Server (HIS). Use one of the following installation methods:

  • Install HIS on the same computer as the Barr software

  • Install HIS Client on the same computer as the Barr software, provided that HIS is installed elsewhere on your network

• Microsoft SNA Server version 3.0 (with Service Pack 1) or later. Use one of the following installation methods:

  • Install SNA Server on the same computer as the Barr software

  • Install SNA Server Client on the same computer as the Barr software, provided that SNA Server is installed elsewhere on your network

• Microsoft SNA Workstation version 4.0 or later. Microsoft SNA Workstation and the Barr software must be installed on the same computer. SNA Server Client cannot communicate with Microsoft SNA Workstation. When configuring SNA Workstation, follow the instructions for Microsoft SNA Server.

• IBM Communications Server for Linux or IBM Communications Server for NT
