BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an alarm display device for automatically notifying a telephone state to a lock-out state in a telephone, and more particularly, The present invention relates to a lockout alarm display and a device in a telephone, which is suitable for preventing an incapability of receiving a telephone call in a receiving function.

Hereinafter, the telephone after the lock-out state in the conventional telephone will be described as follows.

First, about 10 seconds of dialing tone is transmitted to the telephone after the telephone is left unattended.

Next, about 40 seconds of short English and Korean announcements will be sent alternately. After the announcement, a loud howling tone will be sent out for about 60 seconds.

After the noisy Howling tone, the sound signal is silent.

However, according to one embodiment of the related art, when a wrongly placed telephone even after a transmission / reception terminal of a telephone is locked out, the telephone station is in a state of being unable to receive due to a common mistake, It is impossible to exchange various data to be transmitted.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing an embodiment of a telephone in accordance with the present invention. Referring to FIG. 1, there is shown a block diagram of a telephone according to an embodiment of the present invention, including a dial tone, a guidance message, a howling tone, A transmission and reception unit 12 for transmitting and receiving various signals such as a dial tone, a guidance message, a howling tone, a silent signal, voice data and charging information from the subscriber line 10, A handset 14 which is a means for generating various signals such as a dial tone, a guidance message, a howling tone, a silent tone, and voice data and charging information from the transmission / reception section 12 and inputting and outputting voice, A dial tone, and a guidance message received from the telephone 12. A silence check unit 16 for counting the duration of silence by checking only the silence from the signal and voice data such as howling tone and silence and the silence, A microcomputer 18 for processing signal and voice data such as silence and billing information data and for receiving and processing the counted information from the silence checker 16 and a microcomputer 18 counting from the silence checker 16, An alarm display unit 20 for recognizing and receiving the processed silence information and notifying the user of visible and audible alarms, and an alarm display unit 20 for receiving signals and voice data such as a dial tone, a guidance message, a howling tone, A ring detector 22 for receiving only a receive signal and recognizing the ring signal, a ring detector for receiving a ring signal from the ring detector 22 and informing the subscriber of the ring signal, And a raw part 24.

FIG. 2 is a flowchart illustrating an algorithm for generating an alarm signal according to FIG.

If there is no response due to the elapse of about 10 seconds for a dial tone normally transmitted to a general subscriber of a telephone company, a guidance message is sent to notify that the handset is erroneously placed.

If no response is received after a predetermined time has elapsed even after the guidance message is transmitted, the noisy Howling tone is transmitted for a predetermined time (30).

When a certain time elapses after the howling tone is transmitted, a silent sound is transmitted (32).

It is determined whether there is a response from the receiver for a predetermined time after the silence is transmitted (34).

And determining (34, 36) whether or not to output a visible and audible alarm if there is no response after a predetermined period of time.

As described above, according to the present invention, when a user is misplaced due to carelessness or other circumstances in the telephone, the telephone is informed that the user is in a lock-out state, Lt; RTI ID = 0.0 > and / or < / RTI >
