Abstract

PURPOSE:To save an undesired cost relating to the setting revision by sending a password and a setting number setting a DP/PB signal in a form of a PB signal from a caller and setting the DP/PB signal in response to the setting number when the password is coincident in a key telephone set receiving the password and the setting number. CONSTITUTION:A key telephone set TE1 consists of an impulse circuit 1, a speech network 2, a handset 3, a dialer section 4, a pushbutton 5, a DP/PB signal changeover switch 6, a PB receiver 7, a DP/PB signal setting latch circuit 8 and a CPU 9. Then a caller sends a password and a setting number setting the DP/PB signal to the kay telephone set TE1 of a called party in a form of a PB signal and when the password is coincident, the key telephone set TE1 receiving the password and the setting number sets the DP/PB signal. Thus, the setting of the DP/PB signal different from a DP/PB line is easily coped with and an undesired cost relating to the setting revision is saved.

An object of the present invention is to provide a DP-PB signal setting method for a push-button telephone that can easily deal with DP-PB signal settings different from those of a PB line and can reduce unnecessary expenses related to setting change work.

[Means for Solving the Problems] In order to achieve the above objects, the DP-PB signal setting method of a push-button type telephone according to the present invention provides a DP-PB signal setting method for a push-button type telephone equipped with a DP-PB signal setting means. In order to send the corresponding DP-PB double signal to the PB line, the calling party sends the pin number and DP-PB signal to the push-button telephone of the receiving party.
Double signal A setting number to be set is sent as a PB double signal, and when the push-button telephone that receives the PIN and the setting number matches the PIN, DP/P is sent according to the setting number.
This method is characterized by setting B times the signal.

[Embodiment] Hereinafter, an embodiment of the DP-PB signal setting method for a push-button telephone according to the present invention will be described in detail with reference to FIG.

In FIG. 1, TE□ is a push-button telephone.

The push button type telephone TE has an impulse circuit 1, a speech network 2, a handset 3 equipped with a receiver 3a and a transmitter 3b.
, dialer part 4 equipped with a crystal oscillator 4a, button 5 (numeric buttons □ to 3, Kx x, wooden button 1°, # button 12) + DP - PB signal changeover switch 6, P
B receiver 7, DP-PB signal setting holding circuit 8 and CP
A DP line DPL or a PB line PBL is connected to the terminal T1 depending on the type of telephone line.

Further, an impulse circuit 1 is connected to the terminal T, and the impulse circuit 1 is connected to a crystal oscillator 4a provided in the dialer part 4.
Make and break the DP line DPL or PB line PBL at the PB double signal or DP double signal impulse make ratio and minimum pause determined by the timing.

The dialer part 4 temporarily stores the logic based on the operation of the button 5, and uses the stored logic to send the PB double signal via the speech network 2 and the DP double signal via the direct impulse circuit 1 to the DP at a predetermined make-break ratio. Send to line DPL or PB line PBL.

In addition, the speech network 2 removes unnecessary out-of-band components from the PB double signal and connects it to the DP line DPL or the PB line PBL.
In addition to impedance matching for the handset 1
3 and mute the receiver 13a while transmitting the PB double signal and DP double signal.

The PB receiver 7 connected to the terminal T through the impulse circuit 1 receives the PB double signal sent from the DP @ line DPL or the PB line PBL, and sends the password and setting number corresponding to the received PB double signal number. Send to CPU9.

The CPU 9 decodes the password sent from the PB receiver 7, and if the pre-memorized password and the password input from the PB receiver 7 match, the CPU 9 changes the DP mode or PB mode corresponding to the set number to DP-PB. Signal setting holding circuit 8
hold it.

The DP-PB signal changeover switch 6 is a changeover switch that can be operated from the outside of the casing of the push-button telephone TE, and has a normally closed contact 6b.
Base 11! At the potential point, the normally open contact 6a is connected to the power supply element B via the resistor R1, and the movable contact 6c is connected to the CPU 9, respectively, the normally closed contact 6b is connected to the DP signal side, and the normally open contact 6a is connected to the PB signal side.

[Operation of the invention] The telephone line to which the push-button telephone TE□ having the above configuration is connected is P
If the B line is PBL and the DP-PB signal selector switch 6 is set to the DP signal side of the normally closed contact 6b, the push button type telephone is in DP mode, so the PB
P and B signals are not sent to line PBL. When the user informs the manufacturer's or installer's service department of the telephone number and telephone line type of the malfunctioning push-button telephone TE□, the manufacturer's or installer's service department will inform the manufacturer's or installer's service department that the push-button telephone TE has been connected. Call the push-button telephone TE□ from the PB line PBL, check the malfunction status, and input the PB double signal, for example, the PIN number "r103" and the setting number "01" to ra103#.
o1" is sent. The CPU 9 decodes r#103#oIJ input from the PB receiver 7, and since the pre-memorized password "103" matches the password "103" input from the PB receiver 7, the CPU 9 decodes the DP. - Set the PB signal setting holding circuit 8 to the PB mode corresponding to the setting number roIJ.

When the DP-PB signal setting and holding circuit 8 is set and held in the PB mode, the dialer part 4 functions to send out a PB double signal.

The DP-PB signal setting holding circuit 8 in the above embodiment is a RAM area built in the CPU 9 or a non-volatile MOS.
It may also be configured with a type IC, E''FROM, etc.

[Effects of the Invention] The DP-EP signal setting method for a push-button telephone according to the present invention sends a corresponding DP-PB double signal to a DP-PB line to which a push-button telephone equipped with a DP-PB signal setting means is connected. 1.The calling side sends a PIN number and a setting number for setting a DP-PB double signal from the calling side to the push-button telephone on the receiving side, and the push-button telephone that receives the PIN number and setting number inputs the PIN number. Since this method sets the DP-PB double signal according to the setting number when the numbers match, it is possible to easily deal with DP-PB signal settings that are different from those of the DP-PB line, and reduce unnecessary expenses related to setting change work. effective.
