Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication apparatus having a dial pulse circuit and a push button circuit, and having a shortened dial function capable of transmitting both a dial pulse signal and a push button signal to a communication line.

[0002]

2. Description of the Related Art Conventionally, in a communication apparatus (for example, a telephone) having a speed dial function, a usage of the speed dial function is generally to store a destination dial number for each speed dial number. That is,
By inputting this abbreviated dial number, a dialing is automatically performed to a desired destination, and a line is connected to a communication device of the destination.

However, recently, for example, as in the case of transmission to a pager, a call is first dialed to a destination pager to establish a line connection, and then a service number (message number) is entered to input a message. After sending a call, or dialing the other party's communication terminal to establish a line connection, and then various services (eg, seat reservation service, bank balance inquiry service, etc.)
As shown in the operation of inputting a desired service number to receive a call, the number of button operations on the caller side has been dramatically increased.

[0004] For this reason, recently, as a method of using the speed dial function, a service number is stored in series for each speed dial number, following the dial number of the other party, and the speed dial number is simply input. In many cases, it is possible to perform a series of steps from dialing to the destination to transmitting the service number. In this case, for example, when the currently used communication line is a dial pulse line and when the communication line is a push button (tone pulse) line, abbreviated dial data (such as a dial number or service number) stored in the abbreviated dial number is used. Data) registration method is different.

[0005] For example, when the currently used communication line is a dial pulse line, the registration format of the abbreviated dial data is as shown in FIG. Tone switch signal for switching from dial pulse to push button (tone pulse) (usually using an asterisk key "*")
82, and then a desired service number 83 is registered. Such a registration format of the abbreviated dial data is also disclosed in, for example, JP-A-8-331231.

[0006] When the communication line currently used is a push-button line, the registration format of the abbreviated dial data is as shown in FIG. Then, a pause key “P” is registered, and thereafter, a desired service number 93 is registered.

[0007]

As described above, when the type of the communication line used is different, the registration format of the speed dial data registered in the speed dial number is different. Line type changed from dial pulse line to push button line,
Alternatively, when the push-button line is changed to the dial pulse line, the following problem occurs.

That is, it is assumed that the communication line currently used is a dial pulse line, and the speed dial data shown in FIG. 4 is already registered in the speed dial number of the telephone. Then, in this state, when the communication line to be used is changed from the dial pulse line to the push button line and abbreviated dialing is performed, the communication line is originally registered as a tone switching signal 82 for switching to a tone pulse, and The "*" signal, which should not be transmitted, is transmitted to the communication line as it is.

That is, since the "*" signal is converted into an unnecessary digit and transmitted to the communication line, there has been a problem that an erroneous dialing or interruption occurs. The problem is that if the currently used communication line is a push-button line and the speed-dial number of the telephone has already registered the speed-dial data shown in FIG. Also occurs when changing from to a dial pulse line.

[0010] Therefore, when the type of the communication line is changed, the user must re-register the speed dial number, which is a very troublesome operation. The present invention has been made in order to solve such a problem, and its purpose is to regenerate the speed dial data registered in the speed dial number even if the type of the communication line used is changed. An object of the present invention is to provide a communication device having a speed dial function that can be used without registration and with the registered contents before change.

According to a first aspect of the present invention, there is provided a communication device having a shortened dial function, comprising a dial pulse circuit and a push button circuit, wherein a dial pulse signal and a push button are provided. In a communication device that can send any of the signals to the communication line, select a speed dial data storage unit in which speed dial data is stored for each speed dial number, and select a communication line type of dial pulse line or push button line Selection switch, and the speed dial data storage unit stores speed dial data corresponding to the dial pulse line, and when the selection switch selects the push button line, the speed dial number is used. At the time of outgoing call, read from the speed dial data storage unit A transmission control unit that processes a push button switching signal included in the reduced dial data as a distinction signal provided between the dial number and the service number of the abbreviated dial data corresponding to the push button line; I do.

According to a second aspect of the present invention, there is provided a communication device having a speed dial function according to the first aspect, wherein the distinction signal is a pause signal. According to a third aspect of the present invention, there is provided the communication device having the speed dial function according to the first aspect, wherein the transmission control unit stores the speed dial data corresponding to the push button line in the speed dial data storage unit. Is stored, and when the selection switch is selecting the dial pulse line, when a call is made with the abbreviated dial number, the outgoing dial data is included in the abbreviated dial data read from the abbreviated dial data storage unit. The distinction signal
This is processed as a push button switching signal included in the abbreviated dial data corresponding to the dial pulse line.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an electrical configuration of a communication device having a speed dial function (including a one-touch dial function) according to the present invention. A speech network circuit 3 is connected to the communication line 1 via a hook switch 2, and a speech circuit 4 is bidirectionally connected to the speech network circuit 3. Also,
A telephone handset 5 having a built-in microphone and earpiece (not shown) is bidirectionally connected to the communication circuit 4.

The communication line 1 is connected to an incoming call detection circuit 6 for detecting a call signal sent from the other terminal device. The output of the incoming call detection circuit 6 controls the operation of the entire device. The control circuit 7 is connected to the control circuit 7. In addition, a dial pulse signal (hereinafter abbreviated as DP signal) is sent to the communication network 1 and a tone pulse (push button) signal (hereinafter PB) is sent to the speech network circuit 3.
The output of a DP / PB circuit 8 for transmitting a signal (abbreviated as a signal) is connected, and the DP / PB circuit 8 transmits a DP signal or a PB signal to the communication line 1 under the control of the control circuit 7. I have.

The control circuit 7 is connected to a selection switch 9 for setting the communication line mode of the apparatus to a communication line mode of either a DP line or a PB line. Buttons (numeric keys) and various function buttons (♯, *, pause, redial,
A key input unit 10 having various keys such as hold is connected. Further, the control circuit 7 has a configuration in which abbreviated dial data storage section 11 for storing abbreviated dial data inputted from the key input section 10 for each abbreviated dial number is bidirectionally connected.

Next, regarding the speed dialing operation of the communication device having the speed dial function having the above configuration, (1) the speed dial data corresponding to the DP line is stored in the speed dial data storage unit 11, and the selection switch 9
Is selecting the PB line (the common terminal c is connected to the terminal b side).
Speed dial data corresponding to the line is stored,
The case where the selection switch 9 selects the DP line (the common terminal c is connected to the terminal a side) will be described separately with reference to the flowcharts shown in FIGS. 2 and 3.

(1) D is stored in the speed dial data storage unit 11.
Speed dial data corresponding to the P line is stored, and the selection switch 9 selects the PB line (common terminal c).
Is connected to the terminal b) That is, the speed dial data storage unit 11 stores the speed dial data in the signal format shown in FIG.
In other words, when registering the speed dial data, this communication device was used for the DP line. However, for example, the line type is switched from the DP line to the PB line due to a subsequent contract change with a telephone company. I do.

In this case, the selection switch 9 of the communication device is
The connection on the DP line side (that is, the connection between the common terminal c and the terminal a) is switched to the connection on the PB line side (that is, the connection between the common terminal c and the terminal b). The control circuit 7 recognizes that the communication line mode of the apparatus is the PB line mode by the switching operation of the selection switch 9.

In this state, when a speed dial is transmitted (step S1), the control circuit 7 turns on the hook switch 2 and then stores the speed dial data (for example, the data shown in FIG. ) Is read (step S2), the read speed dial data is converted into a tone signal in the PB circuit of the DP / PB circuit 8, and is sequentially transmitted to the communication line 1 (step S2).
3). Here, "123-4567", which is the dial number 81 of the other party, is first transmitted from the DP / PB circuit 8 to the communication line 1 as a tone signal.

Then, when the next "*" signal (tone switching signal 82) comes, the control circuit 7 determines whether this "*" signal is the first "*" signal after the start of transmission (step). S6) If it is determined that the signal comes first, it is processed as a pause signal ("P" signal) (step S7). That is, it is possible to prevent the “*” signal from being transmitted to the communication line 1 as an unnecessary digit. As a result, only the dial number of the other party is transmitted to the communication line 1, so that it is possible to establish a line connection with the registered correct other party.

Then, when the connection with the communication apparatus of the other party is confirmed (step S8), the control circuit 7 determines that the service number 83 registered next to the "*" signal is "89".
024 * 999 "is converted into a tone signal in the DP / PB circuit 8 and sequentially transmitted to the communication line 1 (step S).
3). In this case, when transmitting the “*” signal included in the service number 83, the control circuit 7 transmits the “*” signal.
It is determined whether the signal is the first signal after the start of transmission (step S6). In this case, since the signal is not the first signal, it is processed as a normal "*" signal and transmitted to the communication line 1 (step S9). As a result, the "*" signal is correctly transmitted to the communication line 1 as a signal constituting the service number 83.

When the transmission of all service numbers is completed in this way, the control circuit 7 proceeds from step S4 to step S10, turns off the hook switch 2 and ends the speed dialing operation. In the above description of the operation, the case where the abbreviated dial data is data for the DP line has been described. However, when the abbreviated dial data is data for the PB line as shown in FIG. If the PB line has been changed and the speed dial data for the PB line is additionally registered in the speed dial data storage unit 11), the dial number 91
Next, a pause key “P” is registered. Therefore, in this case, the operation proceeds from step S5 to step S11, and the speed dialing operation corresponding to the PB line is continuously performed as usual.

(2) P is stored in the speed dial data storage unit 11.
The speed dial data corresponding to the B line is stored, and the selection switch 9 selects the DP line (common terminal c).
5 is connected to the terminal a). That is, the abbreviated dial data storage section 11 stores abbreviated dial data in the signal format shown in FIG.
In other words, this communication device was used for the PB line when registering the abbreviated dial data. However, for example, the line type was switched from the PB line to the DP line due to a subsequent contract change with the telephone company. I do.

In this case, the selection switch 9 of the communication device is
The connection on the PB line side (that is, the connection between the common terminal c and the terminal b) is switched to the connection on the DP line side (that is, the connection between the common terminal c and the terminal a). The control circuit 7 recognizes that the communication line mode of the apparatus is the DP line mode by the switching operation of the selection switch 9.

In this state, when a speed dial call is made (step S21), the control circuit 7 sets the hook switch 2
Is turned on, the abbreviated dial data (for example, the data shown in FIG. 5) is read from the abbreviated dial data storage unit 11 (step S22), and the read abbreviated dial data is sent to the DP circuit of the DP / PB circuit 8 by the dial pulse. The signal is converted into a signal and transmitted to the communication line 1 sequentially (step S23). Here, "123-4567", which is the dial number 91 of the other party, is first entered into the DP / PB circuit 8.
The signal is transmitted to the communication line 1 as a dial pulse signal.

Then, when a signal of the next pause key "P" comes, the control circuit 7 determines whether this "P" signal is the first signal after the start of transmission (step S26).
If it is determined that the signal is the first "P" signal, the "P" signal is processed as a tone switching signal corresponding to the DP line (step S27). That is, it is possible to prevent the "P" signal from becoming an unnecessary digit and being transmitted to the communication line 1. As a result, only the dial number of the other party is transmitted to the communication line 1, so that it is possible to establish a line connection with the registered correct other party.

When the connection with the communication device of the other party is confirmed (step S28), the control circuit 7 sets the "P"
"8" which is the service number 93 registered after the signal
9024 * 999 "is converted into a tone signal in the DP / PB circuit 8 and sequentially transmitted to the communication line 1 (step S).
23). At this time, if the “P” signal is included in the service number 93 (not included in FIG. 5), the control circuit 7 transmits the “P” signal.
Determines whether this "P" signal is the first signal after the start of transmission (step S26). In this case, since the signal is not the first signal, it is processed as a normal "P" signal and transmitted to the communication line 1 (step S29). As a result, the "P" signal is correctly transmitted to the communication line 1 as a signal constituting the service number 93.

When transmission of all service numbers is completed in this way, the control circuit 7 proceeds from step S24 to step S30, turns off the hook switch 2 and ends the speed dialing operation. In the above description of the operation, the case where the abbreviated dial data is data for a PB line has been described. However, when the abbreviated dial data is data for a DP line as shown in FIG. In the case where abbreviated dial data for the DP line is additionally registered in the abbreviated dial data storage unit 11 after the change to the DP line), the dial number 81
Next, an asterisk key “*” is registered. Therefore, in this case, the operation proceeds from step S25 to step S31, and the abbreviated dialing operation corresponding to the DP line is continuously performed as usual.
