|
SNA/X.25 Link is composed of only software: SNA/X.25 Link communicates with the X.25 network through the X.25 System Access software on the HP 3000, which is supported by a Datacommunications and Terminal Controller (DTC). The QLLC module enforces the QLLC protocol, which is a special protocol developed by IBM to resolve differences between SDLC and X.25. It uses qualified X.25 packets to send link control messages in a format similar to SDLC link control messages. Figure 1-3 “SNA/X.25 Link HP-to-IBM Host Communication” shows how SNA/X.25 Link, the SNA services, and the required NS products implement HP 3000-to-IBM host communication. Figure 1-4 “SNA/X.25 Link HP-to-AS/400 Communication” shows how SNA/X.25 Link, the SNA services, and the required NS products implement HP 3000-to-IBM AS/400 communication.

For more-specific information, contact your Hewlett-Packard sales representative. SNA/X.25 Link requires this IBM AS/400 hardware:
SNA/X.25 Link requires this IBM AS/400 software: For more-specific information, contact your Hewlett-Packard sales representative. You can run SNA/X.25 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/X.25 Link requires this HP 3000 hardware:
Note that since SNA/X.25 Link requires the X.25 XL System Access product and the DTC/X.25 Network Access product, the required hardware for those products is also required by SNA/X.25 Link. (See the Getting Started with the DTC manual [32098-61000] for more information.) SNA/X.25 Link requires this HP 3000 software: |
