Abstract

PURPOSE:To eliminate the need of an accumulating method for dial signals by repeating and sending tone dial signals from a subscriber's telephone set after conversion and correction one character after another. CONSTITUTION:Tone dial signals sent out from mobile subscriber's telephone set MT arrive at dial register DR by way of transmitter-receiver TRX, both-way trunk BWT and lead 1. Once it is discriminated that those signals are received for a certain time, dial register DR drives PB signal generator PBOSC which generates PB signals, tone dial signals adaptive to switchboard RSW. Those PB signals are sent out to PB originating register PBOR of switchborad SW by way of lead 3, both-way turnk BWT, main link ML and line circuit LC. Those operations are repeated for each tone dial signal from mobile subscriber's telephone set MT.
