Abstract

The present invention relates to a telecommunication system and method enabling a user to get access to automated call processing systems. The system comprises in combination a telephone line interface means adapted to provide the function of a telephone set, a control means connected to the telephone line interface means, and adapted to constantly monitor the telephone line, to analyze a call progress signal and a ring-back tone signal and to switch automatically without human intervention from a pulse-dialling mode to a DTMF-dialling mode upon detection of a ring-back signal validated by a central office. This system also includes a handset and keypad means connected to the telephone line interface means and the control means. The central office processes calls in a pulse-dialling mode. The system enables the user to get access to automated-call processing systems, the access to which is limited to callers equipped with DTMF telephones and central office base DTMF services. The telephone line interface means is adapted to detect the presence of a ring signal on the telephone line, wherein the ring signal is indicating a receiving-call mode. The control means is adapted to detect the presence of a ring-back signal, wherein the ring-back signal is indicating a placing-call mode.
