Barr / RJE 3770
BARR / RJE 3770 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.
BARR / RJE 3770 enables our Mainframe Connectivity application.
BARR / RJE 3770 is designed to facilitate migration to the Windows environment for organizations using the BARR / RJE 3770 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
