This International Standard specifies Supplementary Service Call Transfer (SS-CT), which is applicable to various basicservices supported by Private Integrated Services Networks (PISNs). Basic services are specified in ISO/IEC 11574.
sS-CT is a supplementary service which enables a user to transform two of that user’s calls (of which one must be answered)into a new call between the other two users of the two calls.
Supplementary service specifications are produced in three stages, according to the method described in ETS 300 387.ThisInternational Standard contains the stage l and stage 2 specifications of SS-CT.The stage I specification (clause 6) specifiesthe supplementary service as seen by users of PISNs. The stage 2 specification (clauses 7 and 8) identifies the functionalentities involved in the supplementary service and the information flows between them.
This International Standard contains two stage 2 specifications reflecting different ways of operating the service within thenetwork: transfer by join and transfer by rerouteing.
ln order to conform to this International Standard,a stage 3 standard shall specify signalling protocols and equipmentbehaviour that are capable of being used in a PISN which supports the supplementary services specified in this InternationalStandard.This means that, to claim conformance a stage 3 standard is required to be adequate for the support of those aspectsof clause 6 (stage l) and clauses 7 and 8 (stage 2) which are relevant to the interface or equipment to which the stage 3 standardapplies.
