ITU-T Q.3931.1 PDF

This Recommendation describes the core concepts of testing to establish a performance benchmark for an initial release of a PSTN/ISDN emulation subsystem (PES). The same tests can be used also for legacy PSTN/ISDN networks or for interworking tests between a PSTN/ISDN emulation subsystem and legacy PSTN and ISDN. The metrics measured and reported are for performance of this subsystem under a communications application load. The present document covers only the first of the following four performance aspects.

Part 1: Core concepts.

Part 2: Subsystem configurations and benchmarks.

Part 3: Traffic sets and traffic profiles.

Part 4: Reference load network quality parameters.
