Foreword

This Technical Basis for Regulation (TBR) has been produced by the Digital Enhanced Cordless

Telecommunications (DECT) Project of the European Telecommunications Standards Institute (ETSI).

The present document has been produced by ETSI in response to a mandate from the European

Commission issued under Council Directive 83/189/EEC (replaced by 98/34/EC) laying down a procedure

for the provision of information in the field of technical standards and regulations.

The present document is intended to become a Harmonized Standard, the reference of which will be

published in the Official Journal of the European Communities referencing the Council Directive 98/13/EC

[32] on the approximation of the laws of the Member States concerning telecommunications terminal

equipment, including the mutual recognition of their conformity ("the TTE Directive").

Technical specifications relevant to the TTE Directive are given in annex A.

1 Scope

The present document specifies the technical characteristics particular to telephony applications provided

by terminal equipment which is capable of connection to a public telecommunications network and which

uses Digital Enhanced Cordless Telecommunications (DECT). The cordless transmissions for such

terminal equipment operate within the frequency band 1 880 MHz - 1 900 MHz.

The objective of the present document is to ensure interworking of terminal equipment via the public

network.

The requirements in the present document apply in addition to the attachment requirements for the

appropriate public network and the TBR for DECT general attachment requirements.

The present document is applicable to simple telephony terminals as well as to the telephony function of

multi-function or multi-service terminals.

The present document includes the speech quality and transmission requirements for a 3,1 kHz telephony

teleservice.

For each requirement in the present document, a test is given, including measurement methods. The

terminal equipment may be stimulated to perform the tests by additional equipment if necessary.

The present document is not applicable to terminal equipment specially designed for the disabled (e.g.

with amplification of received speech as an aid for the hard-of-hearing).

DECT comprises two equipment elements, referred to as a Fixed Part (FP) and a Portable Part (PP). The

present document is structured to allow type approval of either a) the FP and PP together, or b) the FP

and PP as separate items. Where the DECT FP is connected to a PSTN, and there are any peculiarities in

the requirements for voice telephony, these shall be accommodated within the FP.
2 Normative references

The present document incorporates by dated or undated reference, provisions from other publications.

These normative references are cited at the appropriate places in the text and the publications are listed

hereafter. For dated references, subsequent amendments to or revisions of any of these publications

apply to the present document only when incorporated in it by amendment or revision. For undated

references the latest edition of the publication referred to applies.
