Abstract

This International Standard defines the signalling procedures and protocol for the purpose of circuit-switched Call Control at

the Q-reference point between Private Integrated Network Exchanges (PINXs) connected together within a Private Integrated

Services Network (PISN).

The Q reference point is defined in ISO/IEC 11579-1.

This International Standard is based upon that described in ITU-T Recommendation Q.931, including the provisions for

symmetrical operation described in annex D of that recommendation.

Service specifications are produced in three stages and according to the method specified in ETS 300 387. This International

Standard contains the stage 3 specification for the Q reference point and satisfies the requirements identified by the stage 1 and

stage 2 specifications in ECMA-142, ECMA-148 and ISO/IEC 11584.

This International Standard is applicable to PINXs which interconnect to form a PISN.

Annex ZC is an integral part of this International Standard.
