6.5.1999 Official Journal of the European Communities L 118/55 (Acts whose publication is not obligatory) COMMISSION COMMISSION DECISION of 12 April 1999 on a common technical regulation for connection to the analogue public switched telephone networks (PSTNs) of terminal equipment supporting the voice telephony justified case service in which network addressing, if provided, is by means of dual tone multi-frequency (DTMF) signalling (notified under document number C(1999) 874) (Text with EEA relevance) (1999/303/EC) THE COMMISSION OF THE EUROPEAN COMMUNITIES, Having regard to the Treaty establishing the European Community, Having regard to Directive 98/13/EC of the European Parliament and of the Council of 12 February 1998 concerning telecommunications terminal equipment and satellite earth station equipment, including the mutual recognition of their conformity ('), and in particular Atrticle 7(2), second indent, thereof, ) Whereas the Council Decision 98/482/EC of 20 July 1998 on a common technical regulation for the attachment requirements for connection to the analogue public switched telephone networks (PSTNSs) of terminal equipment (excluding terminal equipment supporting the voice telephony justified case service) in which network addressing, if provided, is by means of dual tone multi-frequency (DTMF) signalling (*) excludes terminal equipment supporting the voice telephony justified case service; Whereas the Commission has identified that terminal  equipment supporting the voice telephony justified case service should be covered by a common technical regulation; and has identi- fied the associated scope statement; () OJ L 74, 12.3.1998, p. 1. () OJ L 216, 4.8.1998, p. 8. @) Whereas the technical development of the corres- ponding harmonised standard is sufficiently advanced that its content is known to differ only marginally from that of the harmonised standard referenced by the Council Decision 98/482/EC; whereas it is therefore opportune that the existing harmonised standard should be adopted, with minor exclusions, to provide a basis for the attach- ment requirements for terminals supporting the voice telephony justified case service; whereas this can be achieved through this Commission Decision which is complementary to Decision 98/ 482/EC; whereas this will have the effect that the same harmonised standard will be used for the attachment requirements for all kinds of terminals connected to the PSTN; whereas such application of essential requirements with discernment, taking account of the state of the art and economic bene- fits, is foreseen in the recitals of Directive 98/ 13/EG; Whereas the technical development of the national public telephone networks have taken place continuously during the course of the 20th century, and that because these developments were initially undertaken independently, important technical differences wil remain between networks;
