ISO IEC 17878 pdf download – Information technology — Telecommunications and information exchange between systems — Private Integrated Services Network — Inter-exchange signalling protocol — Private User Mobility (PUM) — Call handling additional network features
1Scope
This International Standard specifies the signalling protocol for the support of the Private User Mobility eall handlingadditional network features (ANF-PUMI and ANF-PUMO) at the Q reference point between Private Integrated servicesNetwork eXchanges (PINX) connected together within a Private Integrated Services Network (PISN).
ANF-PUMI is a feature that directs incoming calls to a PUM user within the PISN regardless of the PUM user’s geographicallocation within the PISN, provided that the PUM user’s location is known.
ANF-PUMO permits the PISN to process call requests from a PUM user at the home location, if required.The Q reference point is defined in ISO/IEC 11579-1.
Service specifications are produced in three stages and according to the method specified in ITU-T Rec.1L.130.ThisInternational Standard contains the stage 3 specification for the Q reference point and satisfies the requirements identified bythe stage 1 and stage 2 specifications in ISo/IEC 17877.
The signalling protocol for ANF-PUMl and ANF-PUMO operates on top of the signalling protocol for basic circuit switchedcall control, as specified in ISO/IEC 11572, and uses certain aspects of the generic procedures for the control of supplementaryservices specified in ISO/IEC 11582.
This International Standard also specifies additional signalling protocol requirements for the support of interactions at the Qreference point between ANF-PUMI / ANF-PUMO and other supplementary services and ANFs.
This International Standard is applicable to PINXs which can interconnect to form a PISN.2Conformance
ln order to conform to this International Standard,a PINX shall satisfy the requirements identified in the ProtocolImplementation Conformance Statement (PICS) proforma in annex A.
