scope:

This European Telecommunication Standard (ETS) contains the Abstract Test Suite (ATS) specification for the core part of the Generic Functional Protocol (GFP) for the support of supplementary services of the Inter-exchange signalling protocol, for Private Integrated Services Networks (PISN).

The core part of the GFP excludes the connectionless Application Packet Data Unit (APDU) transport mechanism, the Data Service Element (DSE) protocol, the Application Control Service Element (ACSE) protocol, procedures for carrying manufacturer specific information and requirements only relevant to Originating PINXs for calls and Call Independent Signalling Connections (CISCs) or source PINXs for APDUs and notifications.

The objective of this ETS is to provide conformance tests which give a high probability of inter-operability. This ETS covers the core part of the procedures described in ETS 300 239 [1].

The ISO standard for the methodology of conformance testing (ISO/IEC 9646-1 [5], ISO/IEC 9646-2 [6] and ISO/IEC 9646-3 [7] including Amendment 1 [8]) is used as basis for the test methodology.

This ETS is applicable to implementations which support either a Basic Rate (BR) or a Primary Rate Access (PRA) interface, or both, operating over a leased line. It is applicable to PINXs acting as both transit or end PINXs for calls and Call Related Signalling Connections (CRSC), however it does not include test cases applicable to end PINXs acting as source or originating PINXs.

Annex A provides the Partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma of this ETS.

Annex B provides the Protocol Conformance Test Report (PCTR) proforma of this ETS.

Annex C provides the Tree and Tabular Combined Notation (TTCN) part of this ETS.
