scope:
This Standard. ECMA-163. specifies the supplementary services Calling Name Identification Presentation (SSCNIP), Connected Name Identification Presentation (SS-CONP) and Calling/Connected Name Identification Restriction (SS-CNIR). which are applicable. to .various basic services supported by Private Telecommunication Networks (PTNs). Basic services are specified in ECMA-142.
SS-CNIP, SS-CONP and SS-CNIR are supplementary services which apply to an established call. providing name information to the users.
Service specifications are produced in three stages. according to the method described in ECMA-134.
This Standard contains the stage 1 and 2 specifications of the Name Identification supplementary services. The stage 1 specifications specify the supplementary services as seen by users of PI'Ns. The stage 2 specifications identify the functional entities involved in the supplementary services and the information flows between them.
NOTE 1
The stage 3 specifications, the definition of the networking and access layer 3 signalling protocols to support the supplementary services, are defined in separate ECMA Standards.
The purpose of the stage 1 and stage 2 specifications is to guide and constrain the work on signalling protocols at stage 3.
