Anotácia textu normy ISO/IEC 14843-ed.2.0 :
ISO/IEC 14843:2003 specifies the signalling protocol for the support of the Call Offer supplementary service (SS-CO) at the Q reference point between Private Integrated services Network eXchanges (PINXs) connected together within a Private Integrated Services Network (PISN). SS-CO is a supplementary service which, on request from the calling user (or on that users behalf), enables a call to be offered to a busy called user and to wait for that called user to accept this call. 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 ETS 300 387. ISO/IEC 14843:2003 contains the stage 3 specification for the Q reference point and satisfies the requirements identified by the stage 1 and stage 2 specifications in ISO/IEC 14841. The signalling protocol for SS-CO operates on top of the signalling protocol for basic circuit switched call control, as specified in ISO/IEC 11572, and uses certain aspects of the generic procedures for the control of supplementary services specified in ISO/IEC 11582. ISO/IEC 14843:2003 also specifies additional signalling protocol requirements for the support of interactions at the Q reference point between SS-CO and other supplementary services and ANFs. NOTE Additional interactions that have no impact on the signalling protocol at the Q reference point can be found in the relevant stage 1 specifications. ISO/IEC 14843:2003 is applicable to PINXs which can interconnect to form a PISN.
