11 . General
ISO/IEC ISP 10614 is applicable to interworking units concerned with the use of ISO/IEC 8208 (X.25 Packet Layer Protocol). An RCp.q relay provides the means for a System on one subnetwork to communicate with a System, or make use of facilities, on another subnetwork.
This part of ISO/IEC ISP 10614 defines the RC51.1111 Profile, which is applicable to interworking units opcrating between CSMA/CD LAN subnetworks and PSDNs using virtual calls over a PSTN leased 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 1.1111 X.25 protocol relaying between CSMA/CD LAN subnetworks and PSDNs using virtual calls over a PSTN leased line permanent access.
13 . Scenario
Figure 1 illustrates the configuration of Systems to which the RC5 1.1111 Profile is applicable. The figure Shows two reference Points, but implernentations of RC51.1111 profiles may include any number of subnetwork attachments, with a rcference Point corresponding to each.
