          Dear Customer:

          This kit contains the DIGITAL SNA Peer Server, Version 1.4,
          software and user documentation. Please check the bill of mate-
          rials to see that all the items listed are in your distribution
          kit. If any item is missing or damaged, please contact your

          The DIGITAL SNA Peer Server product supports the DIGITAL UNIX
          Version 4.0 operating system and its associated License Manage-
          ment facility (LMF) requirements.

          Features

          The DIGITAL SNA Peer Server software links TCP/IP and DECnet
          users to the SNA environment. In the non-SNA environment, the
          Peer Server is media independent, allowing you to connect to it
          over Ethernet, token ring, FDDI, or other networks supported by
          DIGITAL UNIX. In the SNA environment, the Peer Server connects
          to SNA nodes over:

          o  SDLC-Synchronous Data Link Control

          o  QLLC-Qualified Logical Link Control (requires X.25 for DIGI-
             TAL UNIX)

          o  LLC2-Logical Link Control type 2 (supports Ethernet, token
             ring, and FDDI)

          Both wide area network (WAN) and local area network (LAN) access
          are supported. As a type 2.1 device, the Peer Server provides
          primary and secondary access to the SNA network, including
          support for multiple concurrent sessions using a given logical
          unit (LU). Support for LU6.2 protocols allows implementation of
          parallel sessions.

          Peer Server features include:

          o  Implemented as an application running on DIGITAL UNIX Alpha
             system.

          o  Multiprotocol support (TCP/IP and DECnet).

          o  Backward compatibility with most DIGITAL SNA access routines
             and applications.

          o  Support for SNA node type 2.1 protocols

          o  Connections into an SNA Advanced Peer-to-Peer network (APPN).

          o  Support for LU6.2 protocols.

 






          o  Support for SNA node type 2.0 protocols for use in tradi-
             tional hierarchical networks.

          o  Includes a TN3270 server that allows TN3270 clients to access
             IBM applications as SNA terminals; TCP/IP is not required on
             the mainframe.
