Abstract

PURPOSE:To realize the transmission of the answer from any extension telephone, by transmitting the call signal simultaneously to several extension telephones and then ringing the bell to carry out the display to one office incoming call. CONSTITUTION:When detecting the arrival of the incoming call to office trunk TRK, central control unit CCU reads out the numbers of all extension telephones EXTi to carry out the incoming display out of the office incoming display extension memory, and then transmits the call signal to the extension telephones corresponding to the above-mentioned numbers at one time. In other words, unit CCU transmits call signal generation start information to call signal generating device RGU. Furthermore, the transmission signal of the call signal is transmitted to call signal transmission control unit RCU which controls the call signal transmission to extension telephones EXTO-EXTn each. As a result, the relay contact corresponding to the extension telephone is closed, and the call signal is transmitted to line circuit LC through the relay contact. Thus the bell of the extension telephone rings to carry out the incoming display.
