Foreword

This Technical Basis for Regulation (TBR) has been produced by the Radio Equipment and Systems (RES)

Technical Committee of the European Telecommunications Standards Institute (ETSI) and was adopted

having passed through the ETSI standards approval procedure.

This TBR covers the general attachment requirements for terminal equipment for the Digital European

Cordless Telecommunications (DECT) common interface.

This TBR contains the procedures and requirements for the type examination of Digital European Cordless

Telecommunications (DECT) equipment supporting a 3,1 kHz telephony teleservice.
The requirements of TBR 6 [22] apply in addition to this TBR.

This TBR is based on the DECT Common Interface ETS 300 175 [1] - [8] and [32], and I-ETS 300 176

[31].

1 Scope

This Technical Basis for Regulation (TBR) 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 European Cordless Telecommunications (DECT). The cordless

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

The objective of this TBR is to ensure interworking of terminal equipment via the public network.

The requirements in this TBR apply in addition to the attachment requirements for the appropriate public

network (see NOTE) and the TBR for DECT general attachment requirements.

NOTE: TBR for basic ISDN, TBR for primary rate ISDN, or national regulations (implementing

ETS 300 001) for Public Switched Telephone Network (PSTN). Interconnection of a
DECT terminal to a GSM network is still under study; in due course, the scope
statement may need amending to reflect this point.

This TBR is applicable to simple telephony terminals as well as to the telephony function of multi-function or

multi-service terminals.

This TBR includes the speech quality and transmission requirements for a 3,1 kHz telephony teleservice.

For each requirement in this TBR, a test is given, including measurement methods. The terminal equipment

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

This TBR 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). This

TBR 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 national peculiarities in

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

3 Definitions and abbreviations
3.1 Definitions
For the purposes of this TBR, the following definitions apply:

Acoustic Reference Level (ARL): the acoustic level that corresponds to a power level of

- 10 dBm0 at the digital interface.

Conducted measurements: measurements which are made using a direct connection to the Equipment

Under Test (EUT).

Duplex bearer: the use of two simplex bearers operating in opposite directions on two physical channels.

These pairs of channels always use the same RF carrier and always use evenly spaced slots (i.e.

separated by 0,5 TDMA frame).

Equipment Under Test (EUT): the equipment submitted to the test laboratory for type examination.

Fixed geometry PP: a PP in which the electro-acoustic transducers and their associated acoustic

components are held in fixed relative positions and/or orientations during all on-line conditions of the PP.

Fixed Part (DECT Fixed Part) (FP): a physical grouping that contains all of the elements in the DECT

network between the local network and the DECT air interface.

NOTE 1: A DECT fixed part contains the logical elements of at least one fixed radio termination,

plus additional implementation specific elements.

Fixed radio Termination (FT): a logical group of functions that contains all of the DECT processes and

procedures on the fixed side of the DECT air interface.

NOTE 2: A fixed radio termination only includes elements that are defined in ETS 300 175 [1] -

[8]. This includes radio transmission elements (layer 1) together with a selection of

layer 2 and layer 3 elements.

Full slot (slot): one 24th of a TDMA frame which is used to support one physical channel.

Handset echo: the echo, perceptible by the far-end user, resulting from the coupling between the receive

and
...
