1、CEPT T/R*52-02*E 93 W 2326414 0012745 381 W TIR 52-02 E Page 1 - Recommendation T/R 52-02 E (Bonn 1993) INTRODUCTION OF TERRESTRIAL DIGITAL AUDIO BROADCASTING (T-DAB) Recommendation proposed by the Working Group “Frequency Management” (FM) Text of the Recommendation adopted by the “European Radiocom

2、munications Committee” (ERC). “The European Conference of Postal and Telecommunications Administrations, considering 1. that development work is being finalized by EUREKA 147, 2. that the intention is to introduce T-DAB in CEPT member countries from 1995, 3. that the band 87.5-108 MHz is currently e

3、xtensively used or FM broadcasting, 4. that an interim frequency band will be necessary for the introduction of T-DAB, 5. that there are different channel plans and different services in the VHF bands in CEPT member countries, 6. that the tuning range of the receiver should be kept to a minimum to r

4、educe equipment costs, 7. that a long period of simulcasting will be necessary until T-DAB receivers achieve sufficient market penetration, O recommends 1. that according to national use and requirements, all or parts of the frequency bands 47-68, 174-222, 222-230 and 230-240 MHz may be used on an i

5、nterim basis for the introduction of T-DAB in CEPT member countries, 2. that the band 87.5-108 MHz will be the future home for T-DAB, 3. that the band 104-108 MHz may also be used on an interim basis for T-DAB subject to coordination with existing services within the same and in adjacent bands, but

6、such an introduction must not prejudice the future replanning of the frequency band 87.5-108 MHz for T-DAB in the CEPT member countries, 4. that the tuning range of the receivers shall cover the frequency bands mentioned in Recommends 1 and 2, 5. that due account should be taken of existing services

7、 in the above bands when introducing T-DAB, 6. that sharing and coordination criteria detailed in Annex 1 * be applied, 7. that a meeting to plan for the introduction of T-DAB in CEPT member countries into the bands mentioned in Recom- mends 1 be arranged in earlv 1994.” * Annex 1 will be developed and should become available at the end of 1993.
