          Processor Restrictions

          o  At least 1.5M bytes of physical memory

          o  Non-paged dynamic pool computed as follows:

          o  At least:

             -  60K bytes for the VAX P.S.I. Access software and data
                storage, plus

             -  13K bytes if the VAX P.S.I. Access X.29 capabilities are
                required, plus

             -  1.5K bytes for each virtual circuit, calculated as:

                <WINDOWSIZE>*<packetsize + 96>*2 + 700 bytes

                which is charged to the quota of the using process.

          VAX Packetnet System Interface Access, Version 4.3   SSA 27.78.02-A



          Block Space Requirements (Block Cluster Size = 1):

          Disk space required for      4,000 blocks
          installation:
                                       (2.0M bytes)

          Disk space required for      2,500 blocks
          use (permanent):
                                       (1.3M bytes)

          These counts refer to the disk space required on the system
          disk. The sizes are approximate; actual sizes may vary depending
          on the user's system environment, configuration, and software
          options.

          A suitable connector node is required for communication by means
          of a PSDN.

          OPTIONAL HARDWARE

          Connector nodes connected to the same or different PSDN(s) may
          be added to the overall network configuration. If communication
          from a VAX P.S.I. Access node with an additional connector node
          is required, or if an existing connector node is connected to an
          additional PSDN(s), the configuration database must be updated.

          CLUSTER ENVIRONMENT

          This layered product is fully supported when installed on any
          valid and licensed VAXcluster * configuration. The HARDWARE RE-
          QUIREMENTS sections of this product's Software Product Descrip-
          tion and System Support Addendum detail any special hardware
          required by this product.

          *  V5.x VAXcluster configurations are fully described in VAX-
             cluster Software Product Description (29.78.xx) and include
             CI, Ethernet and Mixed Interconnect configurations.

          In order to configure some product specific attributes that
          must remain unique to each system, certain components of
          the product are stored in the system specific environment
          (SYS$SPECIFIC:[SYSxxx]) of the VAX computer on which the in-
          stallation is being performed - on common disks. The remaining
          components of the product, including some or all of the exe-
          cutable images, will be installed common to all accessing VAX
          systems.

          Though some or all of the product's executable images will
          exist in the common system directory (SYS$COMMON:[SYSEXE])
          and be executable by all VAX computers sharing this directory,
          it is essential that the product be installed separately on
          all VAXcluster or Local Area VAXcluster licensed VAX systems
          requiring access in order to uniquely configure the product for
          each.

          The same version of VAX P.S.I. Access must be used on all sys-
          tems in VAXcluster systems accessing a common disk and in Local
          Area VAXcluster configurations.

          SOFTWARE REQUIREMENTS

          VMS Operating System V5.1, V5.2 or V5.3.

          DECnet-VAX V5.1 V5.2 or V5.3 (either end-node or full-function)

          For VMS V5.x, the following VMS classes are required for full
          functionality of this layered product:

             VMS Required Saveset
             Network Support
             Utilities
             Programming Support

          GROWTH CONSIDERATIONS

          The minimum hardware for any future version of this product
          maybe different from the minimum hardware requirements of the
          current version.

          DISTRIBUTION MEDIA

          Tape: 9-track 1600 BPI Magtape (PE), TK50 Streaming Tape

          This product is also available as part of the VMS Consolidated
          Software Distribution on CDROM.
