SNA/SDLC Link is composed of hardware and software:
Programmable Serial Interface (PSI) card and cables (hardware)
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 “SNA/SDLC Link HP-to-IBM Host Communication” shows how SNA/SDLC Link and the SNA services implement
HP 3000-to-IBM host communication.

Figure 1-2 “SNA/SDLC Link HP-to-AS/400 Communication” 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) card and 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.
