Defines the signalling protocol for the control of supplementary services and additional network features (ANFs) at the Q reference point in private integrated services networks (PISNs). It is one of a series of Standards applicable to PISN. This Standard is identical with and has been reproduced from ISO/IEC 11582:1995.
Scope
This International Standard defines the signalling protocol for the control of Supplementary services and Additional Network Features (ANFs) at the Q reference point. The protocol is part of Private Signalling system No.1 (PSS1). The Q reference point exists between Private Integrated Services Network Exchanges (PINX) connected together within a Private Integrated Services Network (PISN) and is defined in ISO/IEC 11579. Detailed procedures applicable to individual Supplementary services and ANFs are beyond the scope of this International Standard and will be specified by other Standards for those services which are stan-dardised and by individual manufacturers for proprietary services using the capabilities defined in this International Standard.
ISO/IEC 11572 defines the Layer 3 protocol for circuit-switched call control at the Q reference point. This International Standard defines additional protocol procedures, to be used in conjunction with those defined in ISO/IEC 11572 for the control of Supplementary services and ANFs.
NOTE 1 – Typical examples of the application of these generic functional procedures to some Supplementary services are provided in Annex A, for explanatory and illustrative purposes only.
NOTE 2 – Specific Supplementary services and Additional Network Features may require additional information transfer mechanisms which are service or feature specific and are beyond the scope of this International Standard.
