1 Scope
The present document defines the possibility to assign call diversion supplementary services to a DDI range as an
alternative to assigning supplementary services to the whole hunt group.
The purpose of the introduction of DDI ranges is to fulfil the user requirements concerning the DDI supplementary
service and the interactions with the call diversion supplementary services.
The present document shall be considered as a base for the revision of the interaction sections of the DDI supplementary
service and the call diversion supplementary services.
The ISDN Service enhancements based on DDI ranges for the call diversion supplementary services are applicable to all
circuit-switched telecommunication services.
