The present document specifies a set of functionalities of the New Generation DECT.
The New Generation DECT provides the following basic new functionalities:
? Wideband speech service (part 1).
? Packet-mode data service supporting Internet Protocol with efficient spectrum usage and high data rates (part 2).
? Extended wideband speech services (part 3).
All New Generation DECT devices will offer at least one or several of these services.
The present document describes the part 3: Extended wideband speech services:
? For the description of the wideband speech service, see TS 102 527-1.
? For the description of the support of transparent IP packet data, see TS 102 527-2.
The part 3 "Extended wideband speech services" is defined as an extension of part 1 "Wideband speech service". All devices compliant to part 3 specification (the present document) shall implement at least all mandatory features and
may implement the optional features defined in part 1 "wideband speech". In addition to that, the present document defines additional mandatory or optional features.
The part 1, and therefore part 3, are also defined as extensions of the "Generic Access Profile (GAP)". All DECT devices offering Wideband speech services (part 1 or part 1 plus part 3) shall also be compliant with the "Generic
Access Profile (GAP)", and shall offer the DECT standard 32 kbit/s voice service according to GAP.
All DECT devices claiming to be compliant with this Application Profile will offer at least the basic services defined as
mandatory. In addition to that, optional features can be implemented to offer additional DECT services.
The aim of the present document is to guarantee a sufficient level of interoperability and to provide an easy route for development of DECT wideband speech applications, with the features of the present document being a common fall-back option available in all compliant to this profile equipment.
