ISO/IEC 21407:2001 Information technology - Telecommunications and information exchange between systems - Private Integrated Services Network - Specification, functional model and information flows - Simple dialog supplementary service

Summary

This International Standard specifies the supplementary service Simple Dialog (SS-SD), which is applicable to various basic

services supported by Private Integrated Services Networks (PISNs). Basic services are specified in ISO/IEC 11574.

Supplementary service SD enables a user to communicate with another user or application by the exchange of keypad and

display information transparently over a PISN.

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

Standard contains the stage 1 and stage 2 specifications of SS-SD. The stage 1 specification (clause 6) specifies the

supplementary service as seen by users of PISNs. The stage 2 specification (clause 7) specifies the functional entities involved

in the supplementary service and the information flows between them.
