PURPOSE:To exactly execute a call by storing an inter-call number in a dial signal by an originating subscriber, and sending out a call signal corresponding to an inter- call number which has been prepared for each subscriber to be called. CONSTITUTION:A dial signal from automatic telephone sets Ta1-Tan, Tb1-Tbn, Tc1-Tcn, Td1-Tdn is input to the paging control part 12 through the automatic switchboard 11. The selective calling device 14 selects an inter-call number in the dial signal, and provides it to the paging transmitter 13. The transmitter 13 trasmits a call signal which has been selected by corresponding to the inter-call number, through the leakage synchronizing cable 17. Slave stations Ra1-Ran, Rb1-Rbn, Rc1-Rcn, Rd1-Rdn having the inter-call number receive the inter-call signal from the transmitter 13, and raise a ringing tone. |
