Abstract

PURPOSE:To generate a normal call tone and to attain normal connection by stopping the generation of the call tone immediately when an end of call signal is received in the generation process of the call tone by a ringer signal and generating the call tone in matching with the timing of the ringer signal of a master set for the several number of times. CONSTITUTION:When a call comes to a telephone set from a telephone exchange 30, a 16Hz bell signal is sent in the duty of 2sec:1sec. The bell signal is detected by a ringer signal device 24C of a controller. A CPU 20 calls a slave set according to the telephone number 24A, confirms the switching to a designated channel of the slave set through the channel designation from the channel number (designated) 24B to send a ringer signal synchronously with the bell signal. The slave set sends a ringer reply signal and sound the call signal. A call tone generator 9 of the slave set (A) receives one ringer signal and generates the call tone of its own timing for the several number of times. The ringer signal from the master set (B) is used as a synchronizing signal to correct a trigger start point of its own timing circuit.

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a base unit connected to a public telecommunications network or a private branch exchange via a wired line, and a cordless telephone connected to the base unit via a wireless line. Ringer Method (Prior Art) Conventionally, there is a ringer method for this type of cordless telephone that automatically generates a ringing tone when a telephone number matches, and stops the ringing tone when the footer is turned off. There is also a device that connects using a telephone number, sends a ringer signal, generates a ringing tone, and sends back a response signal. Furthermore, some devices generate a ringing tone several times at their own timing after returning a response signal to the ringer signal.

The second one returns a ringer response and generates a ringer every time a ringer signal arrives, so if the wireless input drops or the reception of the ringer signal is impaired by external noise, the ringer will be cut off each time. Therefore, it had the disadvantage of giving the recipient a sense of abnormality.

The third type is one that generates a ring tone several times when a ring tone arrives once, but small devices such as cordless phones use a large amount of power to generate the ring tone, so the voltage decreases. However, since the reception of the next ringer signal is lost, the ringing tone fluctuates.

The operating current of this ring tone generator requires a large amount of electric power because of the sound pressure of about 80 phon, which causes a decrease in battery voltage. This voltage fluctuation becomes larger if the battery is insufficiently charged. FIG. 2 shows the above operation timing. Next, after receiving one ringer signal, the ringer 9 of the handset (A) generates a ringer several times according to its own timing. This is because the receiver of the Ringer signal is prepared for loss. If a ring tone is generated as described above, the base unit (B
) There is a discrepancy between the ringer signal from the main unit (
Further reception of the ringer signal from B) causes a modulation in the ringer tone. Therefore, the starting point of the movement of the self-timing circuit is corrected by using the ringer signal of the base unit (B) as a synchronization signal. This makes it possible to receive the ringer signal outside the ringing tone generation range.
