Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Digital Enhanced Cordless
Telecommunications (DECT).
The present document is based on ETSI EN 300 175 parts 1 [1] to 8 [8] and ETSI EN 300 444 [12]. General attachment
requirements and speech attachment requirements are based on ETSI EN 301 406 [11] (replacing ETSI TBR 006 [i.2])
and ETSI EN 300 176-2 [10] (previously covered by ETSI TBR 010 [i.3]). Further details of the DECT system may be
found in ETSI 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 [i.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document may become outdated or incomplete within relatively short time-scales.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: "Additional feature set nr. 1 for extended wideband speech services".
Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.
