11 . General
ISO/IEC ISP 10614 is applicable to interworking units concemed with the use of ISO/IEC 8208 (X.25 Packet Laycr Protocol). An RCp.q relay provides the means for a System on one subnetwork to communicate with a System, or make use of facilitics, on another subnetwork.
This part of ISO/IEC ISP 10614 dcfines the RC51.1121 Profile, which is applicable to interworking units opcrating between CSMA/CD LAN subnetworks and PSDNs using virtual calls over a digital data circuit / CSDN leascd line permanent access.
12 . Position within the taxonomy
The taxonomy of profiles is defined in ISO/IEC TR 10000-2. This part of ISO/IEC ISP 10614 defines the profile:
RC5 1.1121 X.25 protocol relaying between CSMA/CD LAN subnetworks and PSDNs using virtual calls over a digital data circuit / CSDN leased line permanent access.
13 . Scenario Figure 1 illustrates the configuration of Systems to which the RC51.1121 Profile is applicable. The figure Shows two reference Points, but implernentations of RC5 1.1121 profiles may include any number of subnetwork attachments, with a reference Point corresponding to each.
