Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Digital Enhanced Cordless
Telecommunications (DECT).
The present document is based on EN 300 175 parts 1 [1] to 8 [8] and EN 300 444 [12]. General attachment
requirements and speech attachment requirements are based on EN 301 406 [11] (replacing TBR 006 [i.2]) and
EN 300 176-2 [10] (previously covered by TBR 010 [i.3]). Further details of the DECT system may be found in
TR 101 178 [i.1].
The present document has been developed in accordance to the rules of documenting a profile specification as described
in ISO/IEC 9646-6 [13].
The information in the present document is believed to be correct at the time of publication. However, DECT
standardization is a rapidly changing area, and it is possible that some of the information contained in the present
document may become outdated or incomplete within relatively short time-scales.
The present document is part 1 of a multi-part deliverable covering the New Generation DECT as identified below:
Part 1: "Wideband speech";
Part 2: "Support of transparent IP packet data";
Part 3: "Extended wideband speech services";
Part 4: "Light Data Services: Software Update Over The Air (SUOTA), content downloading and HTTP based
applications";
Part 5: "Part 5: Additional feature set nr. 1 for extended wideband speech services" (in preparation).

1 Scope
The present document specifies a set of functionalities of the New Generation DECT.
The New Generation DECT provides the following basic new functionalities:
• Wideband voice service.
• Packet-mode data service supporting Internet Protocol with efficient spectrum usage and high data rates.
• Extended Wideband speech services.
• Light Data Services: Software Update Over The Air (SUOTA), Content Downloading and HTTP based
applications.
• Additional feature set nr.1 for Extended wideband speech services (in preparation).
The present document describes the first part: Wideband speech service:
• For the description of the support of transparent IP packet data, see TS 102 527-2 [i.4].
• For the description of the Extended wideband speech services, see TS 102 527-3 [i.5].
• For the description of the Light Data Services: Software Update Over The Air (SUOTA), Content
Downloading and HTTP based applications, see TS 102 527-4 [i.11].
• The description of the additional feature set nr.1 for Extended wideband speech services, will be published as
TS 102 527-5 [i.12].
All New Generation DECT devices will offer at least one or both of these services. If the device offers the wideband
voice service, it will support also the DECT standard 32 kbit/s voice service according to EN 300 444 [12] (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.
