CAN/CSA-ISO/IEC ISP 10613-7-01 (R2005)

This National Standard of Canada is equivalent to International Standard ISO/IEC ISP 10613-7:1994. 1 Scope This International Standardized Profile 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 specifies the subnetwork-type dependent, media dependent requirements that are applicable to an interworking unit using virtual calls over a permanent access to a PSDN. The operation of an interworking unit may involve relaying from one subnetwork to another, and those subnetworks need not be of the same type. This part of ISO/IEC ISP 10613 applies only to communications using PSDN subnetworks with permanent access on which virtual calls are used.
