scope:

The present document (part 1) specifies 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 as described in EN 300 175-1 [i] and EN 300 175-2 [2]).

Part 2 of the present multi-part deliverable specifies tests applicable to DECT speech transmission using ITU-T Recommendation G.726 [14] ADPCM speech codec at 32 kbit/s.

The aims of the present document 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 EN 300 175, which are relevant to these aims.

The tests of EN 300 176 are split into two parts:

• part 1 (the present document) 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 terminal equipment consists of the following elements:

a) Fixed Part (FP);

b) Portable Part (PP);

c) Cordless Terminal Adapter (CTA);

d) Wireless Relay Station (WRS) (FP and PP combined).

Part 2 of the present document is structured to allow testing of either:

a) the FP and PP together; or

b) the FP and PP as separate items.

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