ITU-T Q.3931.3 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 Recommendation covers the third part 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
