scope:

This European Telecommunications Standard (ETS) specifies the approval tests applicable to all Digital Enhanced Cordless Telecommunications (DECT) equipment accessing the DECT frequency band 1 880 MHz to 1 900 MHz (including provisions for testing other or extended frequency bands) and the approval tests applicable to DECT speech transmission using CCITT Recommendation G.726 [14] ADPCM speech codec at 32 kbit/s.

The aims of this ETS are to ensure:

- efficient use of frequency spectrum;

- no harm done to any connected network and its services;

- no harm done to other radio networks and services;

- no harm done to other DECT equipment or its services;

- interworking of terminal equipment via the public network,

through testing those provisions of ETS 300 175, parts 1 to 7 [1] to [7] which are relevant to these aims.

The tests of this ETS split into two parts:

- this part covers testing of radio frequency parameters, security elements and those DECT protocols that facilitate the radio frequency tests and efficient use of frequency spectrum;

- part 2 describes testing of DECT 32 kbit/s ADPCM speech requirements between network interface and DECT PT, or between a DECT CI air interface and alternatively a DECT PT or FT. Part 2 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). Part 2 of this ETS 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.

Additional tests apply for equipment implementing ETSI defined profiles (e.g. GAP, DECT-GSM, DECT-ISDN). These tests are found in related ETSs and may supersede the requirements of this ETS.
