Abstract

PROBLEM TO BE SOLVED: To obtain a telephone system that can set a call tone volume to a level recognizable of being called and call a designated telephone set, even when the call tone volume of a designated telephone set is set to off. SOLUTION: When a ringing detection circuit of a master set detects a ringer signal, an incoming call ringing processing is started (step 301), a CPU controls the ringing of the telephone set and a caller IDIC discriminate whether a caller telephone number received from a telephone line matches by search (step 303) with a telephone number registered in a memory of the master set. In the case that a call tone corresponds to the matching telephone number and the call tone volume of the telephone set is set to be off, the call tone volume is reset to a small tone volume (step 310) and the telephone is made to ring (step 311).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone, and more particularly, to a telephone for setting a calling operation when a designated telephone is called.

[0002]

2. Description of the Related Art FIG. 4 shows an example of a telephone number storage means. FIG. 5 is a flowchart of a conventional incoming call ringing process.

As shown in FIG. 4, reference numeral 401 denotes a column for storing telephone numbers, and reference numerals 402 to 409 denote which telephones ring to correspond to the telephone numbers stored in 401, respectively. One byte is allocated to 402 to 409, the first bit is the parent device, the second bit is the child device 1, and the third bit is the child device 2 in the order of the telephone number. . “1” is stored when the information is associated with the telephone number, and “0” is stored when the information is not associated with the telephone number.

[0004] Reference numerals 411 to 420 show the relationship between telephone numbers and data records of telephones associated with the telephone numbers. For example, with 412 data records,
The telephone number “67890” and the child device 1 are associated with each other. In the data record 420, the telephone number "99"
“999” is associated with the parent device, the child device 3, and the child device 5.

[0005] As shown in FIG. 5, the ringing process starts from step 501. In this ringing process, the master unit controls the ringing of all telephones. When the parent machine receives a call (step 502), a search is made for a match between the telephone number of the calling side received from the telephone line and the telephone number registered in the memory of the parent machine (step 503). As a result of the search, if they do not match, it is regarded as unregistered and a normal ring tone is set (step 507). If there is a matching telephone number, a designated ringing tone at the time of matching is set for the telephone associated with the telephone number (step 506). After setting the ringing tone (step 506 or step 507), it is determined whether the ringing volume is off (step 508). In step 508, the telephone whose ringing volume is turned off only counts the number of rings without ringing (step 510).

For example, as shown in FIG. 4, it is assumed that the telephone number of the calling party is "22222". Since the data record 413 is selected, the telephone set associated with the data record is “child device 2”.

In the incoming call ringing process, the telephone number of the calling side matches the telephone number registered in the master unit (step 50).
3), the corresponding telephone is the handset 2; Therefore, the handset 2
, A ring tone is set when they match (step 506). Next, it is determined whether or not the ringing volume of the handset 2 is set to off (step 508). If it is set to off, the ringing is not performed and the number of calls is counted (step 510). Next, it is determined whether the counted number of calls is equal to the designated number of calls (step 511).
If they are equal, the number match information is cleared (step 513).
By doing so, the telephone number of the caller is temporarily unregistered.

Therefore, when the ringing volume of the handset 2 is set to off, the handset 2 does not ring.

If the handset 2 is called a specified number of times and does not respond (including the case where the ringing volume is turned off and the ringing is not performed), all telephones whose ringing volume is not set to ringing sound.

[0010]

As described above, when the ringing volume of the designated telephone is set to off in the conventional telephone, the designated telephone does not ring. In addition, when the designated telephone is called a specified number of times and no response is received, all the telephones ring. For this reason, the meaning of designating a telephone to receive a call has been lost. SUMMARY OF THE INVENTION It is an object of the present invention to provide a telephone set that can recognize that a call is being made even when the ring volume of a designated telephone is set to off, and that has a meaning of designating the telephone and receiving a call. I do.

[0011]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a method for calling a telephone set even if the calling volume of a base unit or a sub unit corresponding to a telephone number of a calling party is turned off. There is provided a means for setting so that the user can recognize that the user is present.

Further, the setting means operates even when the setting of the calling volume of the base unit or the sub unit called via the extension is turned off.

[0013] Further, the setting means can set the ringing volume to an audible volume.

The message recording unit 115 records a response message in the answering machine mode and a message from the received caller. The hook switch 116 is used when the handset is
It is determined whether or not it is set on the “0”.

A line terminal 117 is connected to an incoming call detection circuit 118 for detecting a ringer signal.
The output of 18 is connected to the CPU 111. Reference numeral 119 denotes a rectifier circuit that prevents the inversion of the voltage polarity of the line terminal 117 from affecting the inside of the telephone, 120 denotes a DP sending circuit that connects / disconnects the line, and 121 denotes a speech network IC that performs 2-wire to 4-wire conversion. The line terminal 117 is connected to the CPU 111 via these lines. A receiver 122, a microphone 123, a speaker 124, and a caller IDIC 125 are connected to the speech network IC 121, and the output of the caller ID IC 125 is a CPU.
111. The caller IDIC 125 is a circuit that determines the telephone number of the received caller. further,
The speech network IC 121 and the CPU 111
In order to perform wireless communication with the slave unit, it is connected to an RF module 127 via a convanter 1C126, and an antenna 128 is connected to the RF module 127.

The child device 200 shown in FIG. 2 has a CPU 231 for controlling the whole child device.
RF module 23 for performing wireless communication with base unit 100
3 and a convanter IC 234 are connected, and an antenna 232 is connected to the RF module 233. Also,

When the ringer signal is detected by the incoming call detection circuit 118, the incoming call ringing process shown in FIG. 3 is started (step 301). In the incoming call ringing process, the CP
U111 controls the ringing of the telephone. When the base unit 100 receives a call (step 302), the caller IDIC 125
A search is made for a match between the telephone number of the calling side received from the telephone line and the telephone number registered in the memory of the master unit (step 303). If the result of the search does not match, it is regarded as unregistered and a normal ring tone is set (step 30).
7). If there is a matching telephone number, a designated ringtone at the time of matching is set for the telephone set associated with the telephone number (step 306). After setting the ringing tone (step 306), it is determined whether the ringing volume is set to off (step 308). If the ringing volume is turned off, the ringing volume is set to an audible volume (step 310) and the ringing is performed (step 31).
1). As the sound volume set in step 310, a sound volume lower than usual can be considered.

For example, as shown in FIG. 4, assume that the telephone number of the calling party is "22222". Since the data record 413 is selected, the telephone set associated with the data record is “child device 2”. The calling party's telephone number matches the telephone number registered in the base unit (step 303), and the telephone set corresponding to the registered telephone number is slave unit 2.
Therefore, a ringing tone is set for the slave unit 2 when the two match (step 306). Next, it is determined whether or not the ringing volume of the handset 2 is set to off (step 308). If it is set to off, the call volume is set to low (step 310) and the ringing is performed (step 311).

The setting of the calling operation at the time of calling the designated telephone operates even when a specific telephone is called via an extension or when a specific telephone is called directly from an outside line. These specific telephones operate in a manner similar to the telephones associated with the telephone number of the calling party.
This will be described with reference to a part of the flowchart of FIG.
The specific telephone called via the extension or directly from the outside determines whether or not the ringing volume after the incoming call is set to off (step 308). If the ringing volume is turned off, the ringing volume is set to low (step 310) and the ringing is performed (step 311).

Although the embodiment of the telephone for setting the calling operation at the time of calling the designated telephone according to the present invention has been described in detail, the present invention is not limited to the above-described embodiment, but departs from the gist thereof. It can be changed within the range not to do.

For example, when the ringing volume is set to off, it is possible to visually recognize that the call is being made by setting a lamp or the like to blink.

Also, the ringing volume to be set is from a very low volume to a very high volume as long as the volume is audible.
Can be set to any volume.

[0027]

As described above, according to the telephone set of the present invention for setting the ringing operation at the time of ringing the designated telephone, it is possible to recognize that the ringing is being performed even when the ringing volume of the designated telephone is set to off. , And it is possible to provide a telephone having the meaning of designating the telephone and receiving a call.
