Abstract

PURPOSE:To run efficiently plural attendant boards through simple operations by providing an attendant board changeover switch on an attendant board and transferring automatically an incoming to other attendant boards when the incoming is obtained on the attendant board in the condition where the switch is depressed. CONSTITUTION:When an attendant board changeover switch 16 is depressed through an attendant board 20a, a control circuit 14 detects the depressing, and transmits that said switch 16 has been depressed to an attendant board control circuit 4 in a main device 1 through a data transmitting/receiving circuit 12 and a data line 9. When an incoming is obtained on the attendant board 20a from an extension telephone set 10, a control circuit 5 detects the incoming, and transfers automatically it to other attendant board 20b, thereby connecting the extension telephone set 10 to an attendant board 2. A trunk line incoming is handled in the same manner. When the attendant board changeover switch 16 is again depressed under such condition of the attendant board 20a, this condition is released, and the incoming from the extension telephone set 10 and the trunk line incoming automatically arrive at the attendant board 20a.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a main device connected to a central office line, and a main device connected to the main device.
This invention relates to a button telephone device comprising a plurality of button telephones connected by paired signal lines and a plurality of reception desks.

Conventional configuration and its problems In general, a 6-button telephone device equipped with multiple reception desks has 2 ・
・7 is well known, but this type of system is divided into a reception desk for the representative and an auxiliary reception desk, so incoming calls are concentrated on the representative reception desk and the auxiliary reception desk There was the problem that the system hardly worked, and there was also the problem that special operations had to be performed to transfer incoming calls from the representative's reception desk to the sender's reception desk.

OBJECTS OF THE INVENTION The present invention eliminates the above-mentioned conventional drawbacks, and aims to provide an excellent button telephone device that can efficiently operate multiple reception desks with simple operations. It is something.

Structure of the Invention In order to achieve the purpose of a dirt floor, the present invention provides a reception desk changeover switch within the reception desk, and when a call is received at the reception desk with this switch pressed, the switch is automatically switched on. , the incoming call is transferred to another reception desk.

The explanatory diagram of the embodiment is one embodiment 3 of the button telephone device of the present invention.
7, in which 1 is the main device, CO, ~C0
rL is a central office line connected to the telephone exchange, 2 is a central office line circuit, and 3 is an extension circuit equipped with a data control circuit and the like.

4 is a reception desk control circuit for controlling the reception desk; 5 is a reception desk control circuit incorporating a microcomputer; and office line circuit 2. Extension circuit 3. A control circuit for controlling the reception desk control circuit 4; 6 is a control line; 7 is a telephone line for the office line; 8 and 9 are the main device 1 and the extension telephone 10. and a communication path and a data line that connect the reception desks 20a and 20b to each other; 11 is a communication circuit provided in the reception desk 20a; and 12 is connected to the reception desk control circuit 4 via a data line 9. 1 is a data transmitting and receiving circuit; 13 is a handset; 14 is a control circuit incorporating a microcomputer;
5 is an input/output circuit equipped with a busy indicator, an extension line selection button, a central office line selection button, etc., and 16 is a reception desk changeover switch.

In the above embodiment, when the reception table changeover switch 16 is pressed on the reception table 20a, the control circuit 14 detects this,
Data transmission/reception circuit 12. The fact that the reception console changeover switch I6 has been pressed is transmitted to the reception console control circuit 4 in the main device 1 through the data line 9. Furthermore, the control circuit 14 lights up a specific pilot lamp provided in the input/output circuit 16 to indicate that the reception desk changeover switch 16 has been pressed. At a predetermined timing, the reception console control circuit 4 transmits to the control circuit 5 through the control line 6 that the reception console changeover switch 16 has been pressed.

In this state, when an incoming call is received from the extension telephone 10 to the reception desk 20a, the control circuit 5 detects this and automatically transfers the incoming call to another reception desk 20b. Connected. Incoming calls from central office lines are handled in the same way. If the reception console 20a presses the reception console changeover switch 16 again in this state, this state is canceled and calls from the extension telephone 10 and calls from the office line are automatically received at the reception console 20a.

As described above, the above embodiment has the advantage that it is possible to prevent incoming calls from concentrating on a particular reception desk with a simple operation, and that it is possible to operate the reception desk more efficiently.

Effects of the Invention Page 5 As is clear from the above embodiments, the present invention is provided with a reception desk changeover switch on the reception desk, and by operating this changeover switch, incoming calls to the reception desk are transferred to another reception desk. It is configured so that special operations can be performed as before.

The present invention has the advantage that it is possible to easily prevent incoming calls from being concentrated on a specific reception desk with a simple operation without having to go through the trouble, and that a plurality of reception desks can be operated efficiently.
