适用范围
The present document specifies the approval tests applicable to all Digital Enhanced Cordless Telecommunications (DECT) equipment accessing the DECT fi-equency 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 ITU-T Recommendation G.726 [17] ADPCM speech codec at 32 kbids. 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 telecommunications network@ through testing those provisions of EN 300 175@ parts 1 [i] to 8 [8] which are relevant to these aims. The tests of EN 300 176 are split into two parts: - 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 (the present document) describes testing of DECT 32 kbids ADPCM speech requirements between network interface and DECT PT@ or between a DECT CI air interface and alternatively a DECT PT or FT. This part 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 consist 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). 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.
