Abstract

PURPOSE:To avoid the repetition of manual dialing for many times by giving a dial tone with a prescribed time interval even if an opposite party is busy and using the speaker of a monitor circuit so as to inform the connecting state. CONSTITUTION:The 1st calling is performed manually by a dial oscillation circuit 3. If the opposite party is busy, a call number is stored in a dial storage circuit 2 to set a timer circuit 1. A dial signal having a call umber stored in the circuit 2 is sent from the circuit 3 with a prescribed time interval set in the circuit 1. When the opposite party is busy, a busy tone call tone detection circuit 4 detects a busy tone to start the circuit 1. The circuit 3 repeats automatically the dialing. When the opposite party replies, the circuit 4 detects the call tone and it is informed to the caller by the speaker connected to a monitor circuit 5.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for making a phone call, when the other party is communicating with the other party, the connection is not established because the other party is talking with someone else, and no connection is made. The present invention also relates to a device used to eliminate the inconvenience of repeated redialing.

[Conventional technology]

When you dial to call the other party for a telephone call, if the other party is busy with another person, the connection is not established and a busy tone is returned. When I realized that the other party was on the line, I had no choice but to put the handset back on the hook, see when the other party had finished, and dial again.

[Problem that the invention seeks to solve]

As mentioned above, even if you call the other party, if the other party is on the phone with another person, it is extremely troublesome and for your mental health to have to manually dial the number until the other party's call is connected. The top is also not desirable.

[Means for solving problems]

In order to solve the above-mentioned problems, the redialing device of the present invention includes a dialing circuit, a dialing memory circuit for storing the telephone number of the recipient, and a telephone number stored in the dialing circuit. a timer circuit for making a dial call; a busy tone/ring detecting circuit for detecting a busy tone or ringing tone returned from an exchange in response to the dialing call and controlling the operation of the timer circuit; and a monitor circuit for monitoring.

〔Example〕

Next, the present invention will be explained using examples.

FIG. 1 is a block circuit diagram of one embodiment of the present invention. In FIG. 1, the first ejection is performed manually using the dial transmission circuit 3. If the other party is in use, the dial storage circuit 2 stores the calling number, and the timer circuit 1
Set. Then, at a certain fixed time interval set by the timer circuit IK, the dial number,
A dial signal of the calling number stored in the memory circuit 2 is transmitted. If the other party is using the busy tone (liT).
) is returned, so the busy tone/ringing tone (BT
-RBT) The detection circuit 4 detects a busy tone and activates the timer circuit 1 to automatically repeat dialing at initially set time intervals until the other party is connected.

When the other party is called, the ring-back tone detection circuit 4 detects the ring-back tone, which is notified to the caller by the speaker connected to the monitor circuit 5, and the timer circuit 1 to cancel the time setting. A speaker is connected to the monitor circuit 5, so that the dial pulse sound when making a call, the busy tone/ringing tone returned from the other party, and the call tone from the other party can be monitored, and the connection status can be monitored. It is easy to understand.

〔Effect of the invention〕

As explained above, the redialing device of the present invention can automatically make a busy call at a certain time interval even if the other party is busy, and furthermore, the connection status can be easily transmitted to the speaker of the monitor circuit. This eliminates the traditional annoyance of predicting when a call with another person will end, only to have to manually dial the number over and over again when the prediction is incorrect.
