Foreword This European Standard (Telecommunications series) has been produced by ECMA on behalf of its members and t
11、hose of the European Telecommunications Standards Institute (ETSI). The present document is one of a series of standards defining services and signalling protocols applicable to Private Integrated Services Networks (PISN). The series uses the Integrated Services Digital Network (ISDN) concepts as de
12、veloped by ITU-T and conforms to the framework of standards for Open Systems Interconnection (OSI) as defined by ISO/IEC. The present document specifies the signalling protocol for use at the Q reference point in support of the Message Waiting Indication supplementary service. The protocol defined i
13、n the present document forms part of the PSS1 protocol (informally known as QSIG). The present document endorses an International Standard, ISO/IEC 15506.
