SNA/SDLC Link Overview 

SNA/SDLC Linkis composed of hardware and software:

   *   Programmable Serial Interface (PSI) card and cables (hardware)

   *   SNA Transport (software)

   *   SDLC link driver (software)

The hardware of SNA/SDLC Link (the PSI and cables) and the downloaded SNA
Transport software implement the Physical Control layer of SNA, and the
SDLC link driver implements the Data Link Control layer.  The SDLC link
driver controls transmission over the communications line.

Figure 1-1 shows how SNA/SDLC Link and the SNA services implement HP
3000-to-IBM host communication.

Figure 1-2 shows how SNA/SDLC Link and the SNA services implement HP
3000-to-IBM AS/400 communication.

Host Hardware and Software Requirements 

SNA/SDLC Link requires this IBM host hardware:

   *   An IBM System/370-compatible mainframe (for example, Model 370,
       303x, and 43xx).

   *   An IBM 37xx-compatible communications controller 
       that supports an SNA line.  An HP 3000 can also be connected to
       the communications controller via an IBM 3710 network controller.

SNA/SDLC Link requires this IBM host software:

   *   MVS/SP, MVS/XA, VSE, or VM operating system.

   *   ACF/NCP network control program.  (For a T2.1 node, version 5
       release 2 or later is needed for the IBM 3720 and IBM 3745, and
       version 4 release 3 is needed for the IBM 3725.)

   *   ACF/VTAM telecommunications access method.  (For a T2.1 node,
       version 3 release 2 or later is needed.)

For more-specific information, contact your Hewlett-Packard sales
representative.

AS/400 Hardware and Software Requirements 

SNA/SDLC Link requires this IBM AS/400 hardware:

   *   An IBM AS/400 computer system with the appropriate communications
       controller card installed.

SNA/SDLC Link requires this IBM AS/400 software:

   *   OS/400 operating system (all SNA-related software is included
       within the OS/400 operating system).

For more-specific information, contact your Hewlett-Packard sales
representative.

HP 3000 Hardware and Software Requirements 

You can run SNA/SDLC Link on any 900 Series HP 3000 computer that has at
least 32MB of real memory.  Depending on your system configuration, more
memory might be required.  Contact your Hewlett-Packard sales
representative for more information.

SNA/SDLC Link requires this HP 3000 hardware:

   *   A 900 Series HP 3000 computer system.

   *   A Programmable Serial Interface (PSI) cardand the appropriate PSI
       cables (contact your Hewlett-Packard sales representative for more
       information).  One PSI is required for each active link to the
       remote system.

   *   A switched or leased full-duplex or half-duplex data
       communications line between the HP 3000 and the remote system.
       Note that whether full-duplex or half-duplex transmission is used
       is determined by the remote system configuration or the modem used
       on the remote system.

   *   A block mode terminal 
       that is supported by VPLUS, for use with the Node Management
       Services (NMS) NMMGR configuration manager.

SNA/SDLC Link requires this HP 3000 software:

   *   HP 3000 Multiprogramming Executive with Integrated POSIX (MPE/iX)
       operating system.
