Abstract
PURPOSE: To control easily the simultaneous transmission of ringing signals to several subscribers and the transmission of inter-ringing signals different in kind, by lightening a load on software by controlling the ringing-signal transmission by a time-division switchboard by hardward.
CONSTITUTION: In the switchboard system which transmits subscriber calling signals from respective subscriber circuit coordinate parts, remote line concentrator RLC is provided with subscriber's circuit LC, ringing generator RG and remote line-concentrating network RLCN, and ON-OFF signal generator TIC and central controller CC are both connected to time-division switch network TDSW. Then, controller CC actuates generator TIC via time-division switch netword TDSW and circuit LC is controlled by the output signal of generator TIC as if the hardware did, so that the simultaneous transmission of ringing signals to desired subscriber Sub and the transmission of inter-ringing signals different in kind will be carried out.
