CAN/CSA-ISO/IEC ISP 10613-18-99 (R2008)

This National Standard of Canada is equivalent to International Standard ISO/IEC ISP 10613-18:1995. 1 Scope 1.1 General ISO/IEC ISP 10613 is applicable to interworking units concerned with operating in the Open Systems Interconnection (OSI) environment. It specifies a combination of OSI base standards that collectively provide a network-relay function for the connectionless-mode Network Service. This part of ISO/IEC ISP 10613 defines the RA54.1121 profile, which is applicable to interworking units operating between FDDI LAN subnetworks and PSDNs using virtual calls over a digital data circuits/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 10613 defines the profile: RA54.1121 Relaying the Connectionless-mode Network Service between FDDi LAN subnetworks and PSDNs using virtual calls over a digital data circuit/CSDN leased line permanent access.
