Abstract

PURPOSE:To prevent the trouble of a wrong call or a malicioua call by informing selectively only an incoming call by a specific call tone attended with the transmission of a prescribed signal tone to a user of a telephone set so as to make an incoming call by an unspecified caller ineffective. CONSTITUTION:When the telephone number of a telephone set A is dialed from a telephone set B and a channel is set via the response/control circuit 5 of the telephone set A, the telephone set B sends the signal tone of a prescribed frequency decided wIth the telephone set A from a signal tone sending circuit (b) for a prescribed time. A signal tone detection circuit 6 detects the signal tone in the telephone set A and gives it to the circuit 5. When the circuit 5 detects that the signal tone continues for a prescribed time, the circuit 5 discriminates the caller is a specific person to start a bell drive circuit 8 and a lamp drive circuit 9 for ringing a bell and lighting a lamp. If an unspecified person calls from a telephone set C to the telephone set A, since no signal tone of the prescribed frequency is sent, no line setting is applied via the circuit 5. Thus, a trouble due to a malicious call or a wrong dial is prevented.

Telephone A, which is capable of selective incoming call notification function, includes a telephone circuit 1 similar to existing telephones, a transmitter 2, a receiver 3, and a dial board 4 connected to this telephone circuit.
It includes a response/control circuit 5, a signal sound detection circuit 6, a message sending circuit 7, a bell drive circuit 8, and a lamp drive circuit 9.

When the telephone aA receives this ring tone, it does not notify the user of the incoming call by ringing the bell or the like. When the telephone response/control circuit 5 detects this ringing signal,
A response signal is returned to the subscriber exchange by automatically transitioning the subscriber line into a closed loop state. When the local exchange detects this response from telephone A, it stops sending the ringing signal to the telephone and the ringback tone to telephone B, and sets up a communication path between telephones A and B. do.

When the signal tone detection circuit 6 in the telephone A detects a signal tone of a predetermined frequency sent from the telephone B, it supplies a detection signal to the response/control circuit 5. When the response/control circuit 5 detects that this detection signal has continued for a predetermined period of time, the response/control circuit 5 determines that the caller is a specific person and activates the bell drive circuit 8.
Then, the lamp drive circuit 9 is activated to start ringing the bell and blinking the lamp, thereby notifying the user of the telephone that an incoming call has occurred from a specific person.

In parallel with the notification of the incoming call, the response/control circuit 5 activates the message sending circuit 7 and sends a message to the telephone B via the telephone circuit 1 indicating that the user is being called. When the user of telephone A notices the notification of an incoming call and takes the handset off-hook, the response/control circuit 5 that detects this disconnects the signal sound detection circuit 6 and message sending circuit 7 from the subscriber line, and connects the handset to the telephone. 2 and the receiver 3 are connected, and the operations of the bell drive circuit 8 and the lamp drive circuit 9 are stopped. Thereafter, a conversation between the users of telephones A and B begins in the same way as in a normal case.

On the other hand, when an unspecified person calls telephone A from telephone C, the telephone MA automatically responds. However, the caller from telephone aC does not know that telephone A is equipped with the above-mentioned selective call receiving function, or even if he knows this, he does not know the signal tone of the predetermined frequency, so he cannot receive such a signal from telephone 6c. No signal tone is emitted. When the response/control circuit 5 detects that a predetermined signal tone is not sent even after a predetermined period of time has elapsed since the automatic response, the response/control circuit 5 assumes that the caller is an unspecified person and sends the message from the message sending circuit 7 to the telephone A. An appropriate message is sent to the effect that the user is unable to respond, for example, a message to the effect that the user is absent. If the calling telephone is not on-hook even after a predetermined period of time has passed after sending the message, the response/control circuit 5 sends an on-footer signal to the subscriber exchange by releasing the closed loop state of the subscriber's line, and disconnects the line. cut.
