Abstract

PURPOSE:To eliminate the need for setting a night state by the key operation of an attendant board by changing over automatically a telephone set to the 2nd key telephone set if no operation is conducted for a prescribed time or over by the 1st key telephone set for receiving. CONSTITUTION:When the specific 1st key telephone set Tl is designated as a telephone set for reception by the key operation of an attendant board 11, an individual incoming tone designation circuit 4 rings the 1st key telephone set Tl only from an external line incoming tone. When operations such as key operation, on-hook and off-hook are conducted to the 1st key telephone set Tl, central processing unit 10 clears a timer 7. The timer 7 counts the time after the 1st key telephone set Tl is operated finally and when the count value exceeds a prescribed value, a night state circuit 8 controls the individual incoming tone designating circuit 4 so as to allow the specific 2nd key telephone set Tl' to ring an external incoming tone thereby attaining the night state.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a key telephone device equipped with a switch circuit that can arbitrarily connect a plurality of key telephones and a plurality of outside lines. This invention relates to improvements to a circuit that allows calls to be received only to specific telephones.

Conventionally, in this type of key telephone device, only a specific first key telephone generates a ring tone in response to an incoming call from an outside line by operating a button on the reception desk, and this telephone is used for reception. I have to. Then, at night when the receptionist is absent, by operating a button on the reception desk, a specific second button telephone is changed to play a ringtone from an outside line. The above-mentioned conventional device is cumbersome because it requires a button operation on the reception desk to set it to night mode, and if the receptionist is absent without performing this operation, the first Since the ringtone only sounds on the button telephone, there is a drawback that incoming calls from outside lines cannot be accepted.An object of the present invention is to solve the above-mentioned conventional drawbacks, and to provide a first button for reception. If the telephone is not operated for a certain period of time, the key telephone automatically switches to the night mode in which the second key telephone rings for an incoming call, making it easier to set the night mode by pressing the button on the reception desk. The goal is to provide equipment.

The telephone device of the present invention is a key telephone device equipped with a switch circuit that connects a plurality of key telephones, a reception desk, and a plurality of outer edges, and connects any button telephone to any outside line. an individual ring tone designation circuit that is set by an operation and controls the switch circuit so that a ring tone is supplied only to a specific first button telephone when a call is received; and a button operation of the first button telephone or turning on the handset. , a timer that is cleared every time the button is turned on and counts the period of no operation of the first button telephone; and when the timer counts a certain value or more, the individual ring tone designation circuit is controlled to select a specific second button telephone. and a nighttime state circuit for causing a ringtone to be supplied to the user.

Next, the present invention will be explained in detail with reference to the drawings.

The figure is a block diagram showing one embodiment of the present invention. That is, a plurality of outside line lines, ~L, are connected to the switch matrix 3 via a trunk line 2, and a plurality of key telephones T1 to T, are connected to the switch matrix 3 via a voice interface circuit 6. ing. Also,
Button telephone T, ~T.

Button information generated by button operations on the button and button operations on the reception desk 11 is sent to the central processing unit 10 via the data transmitting/receiving circuit 9.
can be conveyed to. The central processing unit 10 analyzes the button information, controls the connection of the switch matrix 3, and connects each of the button telephones T1 to T to a desired outside line. Therefore, calls from each button telephone can be made by specifying any outside line by operating the buttons.

In the case of an incoming call, if an unspecified key telephone is used to answer the call, it will cause confusion, so if the individual ring tone designation circuit 4 is set by button operation on the reception desk 11, only the specific first key telephone will receive an incoming call from an outside line. The connection of the switch matrix 3 is controlled so that it sounds in response to the noise. In addition, the reception desk 11 displays the usage status of each telephone based on information provided from the central processing unit 10 via the data transmission/reception circuit 9, and also accepts incoming calls and connects an outside line to the telephone for the purpose of the call. The switch matrix 3 is controlled via the central processing unit 10 to provide services such as switching and calling. The central processing unit 10 periodically scans each button/telephone via the data transmission/reception circuit 9, sends out various lamp information, and monitors the button information.
Controls the entire device. The individual ring tone designation circuit 4 supplies the output of the tone circuit 5 only to a specific first button telephone, for example, TIJ, via the switch matrix 3 when a call is received from any outside line by operating a button on the reception desk 11. do. The timer 7 is cleared every time a button of the first button telephone T is pressed.
Count the time since J was last operated. timer 7
When the count value exceeds a certain value, the nighttime state circuit 8 controls the individual ringtone designation circuit 4 to enter the nighttime state. The individual ringtone designation circuit 4 includes a switch matrix 3 so as to ring a specific second button telephone when a call arrives in the nighttime state.
control. The central processing unit 10 is connected to each telephone T, -T.

It also performs analysis processing of data input from the reception desk 11 via the data transmission/reception circuit 9, and controls the entire apparatus.

Next, the operation of this embodiment will be explained. First, reception desk 1
When a specific first button telephone T is designated as a reception telephone by button operation 1, the button information from the reception desk 11 is sent to the central processing unit 1 via the data transmission/reception circuit 9.
0, and the individual ring tone designation circuit 4 sets the external line ring tone to ring only the first key telephone TJ. The first key telephone T is used for reception. The hook information and button information of each button telephone are transmitted to the central processing unit 10 at regular intervals, and button operations or operations such as on-hook and off-hook are performed on the first button telephone TJ. Then, the central processing unit 10 clears the timer 7. Therefore, the timer 7 counts the time since the first button charger Ti was last operated. When the count value of the timer 7 exceeds a certain value, the night state circuit 8 controls the individual ring tone designating circuit 4 to make the specific second button telephone set ring an outside line ring tone, thereby placing it in the night state. . In this state, button operation on the first button telephone T, on-hook,
When some operation such as off-hook is performed, the central processing unit 10 clears the timer 7, the night state circuit 8 is also reset, and the individual ringtone designation circuit 4 sets the outside line ringtone to the first
Press the button T on the telephone to return it to a ringing state and return to the normal state. That is, it is not necessary to set or cancel the nighttime state by operating a button on the reception desk.

As described above, in the present invention, the reception telephone (first
The system is equipped with a timer that is cleared each time a second button telephone is operated and counts the time when the reception telephone is not operated, and when the count value of the timer exceeds a certain value, a ring tone is sounded on the second button telephone at night. The present invention is configured so that when the first button telephone is switched to the state and some operation is performed on the first button telephone, the timer is cleared and the first button telephone is returned to a normal state in which a ringtone sounds. , it has the effect of eliminating the need to set and release the night state by operating the button on the reception desk.
