This EN (harmonised standard) specifies the technical characteristics (electrical and mechanical interface requirements and access protocol) under Articles 4(d) and 4(f) of Directive 91/263/EEC to be provided by a single terminal equipment which is intended (a) for pan-European approval and (b) for connection by two wires to an analogue interface of the PSTN. This interface is characterized by d.c. loop seizure and clearing, uses low frequency a.c. ringing below the speech passband to indicate an incoming call and in the transmission phase has an approximate bandwidth of 3kHz at the network termination point, and (c) for supporting any telephony service.
