Abstract

This TBR specifies the technical characteristics (electrical and acoustic requirements) under Article 4(g) of Directive 91/263/EEC to be provided by a single, handset telephony, terminal equipment which is intended: (a) for pan-European approval; and (b) for connection by 2-wires to an analogue interface of a PSTN. This interface is characterized by a d.c. loop to indicate seizure and clearing, low frequency a.c. ringing signals below the speech passband to indicate an incoming call and in the transmission phase has an approximate bandwidth of 3 kHz at the network termination point; and (c) for supporting the voice telephony justified case service. Work item supported by Nortel, BT, Siemens, CSELT, BAKOM/OFCOM, GPT.
