Scope

1.1

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 RC51.1121 profile, which is applicable to interworking units operating between CSMA/CD LAN subnetworks and PSDNs using virtual calls over a digital data circuit / CSDN leased line permanent access.

1.2

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:

RC51.1121

X.25 protocol relaying between CSMA/CD LAN subnetworks and PSDNs using virtual calls over a digital data circuit / CSDN leased line permanent access.

1.3

Scenario Figure 1 illustrates the configuration of systems to which the RC51.1121 profile is applicable. The figure shows two reference points, but implementations of RC51.1121 profiles may include any numb er of subnetwork attachments, with a reference point corresponding to each. See more
