Digital Enhanced Cordless Telecommunications (DECT); Test specification; Part 1: Radio
The present document specifies tests applicable to all Digital Enhanced Cordless Telecommunications (DECT)*equipment accessing the DECT frequency band 1 880 MHz to 1 900 MHz and including provisions for testing other or*extended frequency bands as described in ETSI EN 300 175-1 [i.11] and ETSI EN 300 175-2 [1]. Part 2 of the present*multi-part deliverable [i.15] specifies tests applicable to DECT speech and audio transmission using a collection of*speech codecs, including Recommendation ITU-T G.726 [i.7] ADPCM codec, Recommendation ITU-T G.722 [i.8]*"7 kHz codec", "MPEG-4 codec" [i.10], LC3plus [i.24] and others.*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.*The tests of ETSI EN 300 176 are split into two parts:*• the present document (part 1) 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 [i.15] describes testing of speech and audio 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);*e) Hybrid Part (HyP) (a PP with capability to act as a FP to provide PP to PP communication).*Details of the DECT Common Interface may be found in ETSI EN 300 175-1 [i.11], ETSI EN 300 175 parts 2 to 3 [1]*to [2], ETSI EN 300 175-4 [i.12], ETSI EN 300 175 parts 5 to 6 [3] to [4], and ETSI EN 300 175 parts 7 to 8 [i.13] to*[i.14]. Further details of the DECT system may be found in the ETSI Technical Report ETSI TR 101 178 [i.1].*Information about ULE may be found in the ETSI Technical Specifications ETSI TS 102 939-1 [i.20] and ETSI*TS 102 939-2 [i.21]
