scope:
This draft European Telecommunication Standard (ETS) has been produced by the Communication, Networks, and Systems Interconnection Technical Committee (TC32) of ECMA on behalf of its members and those of the European Telecommunications Standards Institute (ETSI) and is now submitted for the Unified Approval Procedure (UAP) phase of the ETSI standards approval procedure.
The protocol defined in this ETS is the basis for the QSIG protocol for signalling at the Q reference point between Private Integrated services Network eXchanges (PINX). The QSIG protocol is known as "Private integrated Signalling System no. 1" (PSS1) in International Standards.
Whilst this particular ETS defines signalling for the support of circuit-mode bearer services, other ETSs specify other aspects of the QSIG protocol, e.g. generic procedures for the support of supplementary services, and individual supplementary services.
The previous (second) edition of this ETS contained a "standalone" definition of the protocol. This edition endorses an International Standard, ISO/IEC 11572, published since the publication of the second edition of this ETS.
