Filed: 1986-11-13
Abstract: PURPOSE:To exclude a call from an unspecified person not knowing a registered dial by providing a request signal output circuit, a signal changeover switch connecting the request signal output circuit to a line interface and an additional dial reception circuit in a conventional master equipment. CONSTITUTION:When a line interface circuit 4 of a master equipment 1 acquires a line having an incoming call, a control section 12 outputs a switch signal to the circuit 4. A signal changeover switch 11 receiving a switching signal outputs an output of the circuit 10 to the circuit 4, which sends the additional dial request signal of the circuit 10 to the acquired line. After the signal is sent, if the additional dial is not sent within a specified time, the control section 12 restores the said line. When the additional dial is sent within a specified time, the additional dial reception circuit 9 receives it and gives an output to the circuit 4. The control section 12 compares the inputted additional dial with the registered dial stored and only when they are coincident, the switch 11 is turned off to start conventional channel connection control.
