Abstract

PURPOSE:To surely inform a caller of the correspondence of a called person by allowing an incorporated speaker to produce an audible sound based on the result of detection of the correspondence to a station detecting circuit when on-hook origination is made from a telephone set. CONSTITUTION:When on-hook origination is made form a key telephone set Tk if the called person responds to the call, this is detected by station response detecting circuit 20i, and a detection signal is supplied to a control circuit 50. The control circuit 50 confirms that the response is made to the on-hook origination, and the responce to station data are sent out to the push-button telephone set Tk that made on-hook dial origination from a data interface circuit 41. In the push-button telephone set Tk, audible sound produced in the telephone set by the responding data to a station is outputted for a fixed time from an incorporated speaker. Thereby, the caller is noticed that the called person (station) made the responce.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a button telephone device that temporarily outputs an audible sound from a button telephone by detecting a game response when making an on-footer dial call.

[Conventional technology]

In recent years, key telephone devices with various functions have been provided in order to simplify office processing. The on-hook call function is also one of the features that is attracting attention. In other words, you can make a call with the receiver on, and depending on the other party's response, you pick up the receiver and begin the conversation. According to this, the calling time of the other party is not wasted.

[Problems to be solved]

In the conventional button telephone device described above, when making an on-hook dial call from the button telephone, the button telephone did not output an audible sound even if the call was answered. Need to monitor. However, in a noisy office environment, it is difficult for the caller making an on-hook dial call to hear the voice output from the speaker, and if the response voice of the game is low, it is difficult to confirm the game's response. Ta.

[Means for solving problems]

This invention has been made in view of the above circumstances, and includes a plurality of telephone lines and a plurality of button telephones that can make calls via the telephone lines, have a built-in speaker, and can make on-hook calls. In the key telephone device, a game response detection circuit is provided corresponding to each of the plurality of office lines and detects a response from the called party, and is used when an on-hook call is made from one of the button telephones. and a control circuit that supplies a response signal to the one-button telephone based on the detection result of the game response detection circuit corresponding to the office line, and upon receiving the response signal, the built-in speaker emits an audible sound. It is characterized by emitting.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a key telephone device according to an embodiment of the present invention. In this figure, the button telephone device consists of a main device 1 connected to a plurality of curves Ll, L2...Ln, and a plurality of button telephones TI, T2...Tm connected to this main device 1. The main device 1 further includes a central office line interface section 2, a communication path switch section 3, a telephone interface section 4, and a control circuit section 5.

The office line interface section 2 includes each office line TI.

T2... Corresponding to Tn, game response detection circuit 201゜2
02...20n are provided, and game response detection circuits 20+, 202...20. detects that the called party has responded and supplies a response signal to the control circuit section 5.

Further, the office line interface section 2 is provided with an interface circuit 21, and this interface circuit 2
1 closes a communication path between the incoming central office line and the communication path switch unit 3 under the control of the control circuit unit 5 when a call is received (DC connection), while when making a call, the communication path switch A communication path is established between the section 3 and the vacant station line (DC connection).

Under the control of the control circuit 5, the call path switch section 3 switches and connects any central office line and any key telephone T.

Further, the telephone interface section 4 includes a voice interface circuit 40 and a data interface circuit 41, and the voice interface circuit 40 is connected to a central office line switched and connected by the communication path switch section 3, and a button telephone T.
electrically connect with.

The data interface circuit 41 is connected to the button telephone TI.
The calling data outputted from T2...T is supplied to the control circuit section 5, and when the game response detection data is supplied from the control circuit section 5, the game response data is supplied to a specific key telephone T. Note that the button telephone T has a built-in speaker, and the game response data is supplied from the data interface circuit 41, and an audible sound is emitted to attract the caller's attention.

The control circuit unit 5 includes a control circuit 50 and a data transmitting/receiving circuit 5.
The data transmitting and receiving circuit 51 transmits and receives data to and from the data interface circuit 41.

Further, the control circuit 50 controls each part of the main device 1, and when on-hook transmission data is supplied via the data interface circuit 41 and the data transmission/reception circuit 51, the control circuit 50 controls the detection result of the game response detection circuit 20. Based on this, game response detection data is supplied to the data transmitting/receiving circuit 41.

In the above configuration, a button telephone T not particularly shown
When an on-hook call is made from Tk, the data interface circuit 41 of the telephone interface section 4 sends the on-hook call data of the button telephone Tk to the data transmitting/receiving circuit 51 of the control circuit section 5, and the data transmitting/receiving circuit 5
1 to the control circuit 50. As a result, the control circuit 50 first controls the interface circuit 21 of the station line interface section 2 to capture (directly connect) any station line Li among the vacant station lines.

Next, the call path switch section 3 is controlled to connect the voice line of the button telephone Tk via the voice interface circuit 40 of the telephone interface section 4 to the central office line L+. This will initiate a call to the other party.

When the other party responds to the call, this is detected by the game response detection circuit 20i, and a detection signal is sent to the control circuit 5.
0.

The control circuit 50 confirms that the above response is to the on-footer transmission, and then the data transmission/reception circuit 51
The data is sent to the data interface circuit 41 via.

As a result, from the data interface circuit 41,
Game response data is sent to the key telephone Tk that made the on-footer dial call, and the key telephone Tk
Based on the game response data, an audible sound generated inside the telephone is output from the built-in speaker for a certain period of time. As a result, the caller is reminded that the other party (player) called by on-hook dialing has responded. Note that the game response detection circuit 20 of the station line interface unit 2 described above
1 to n, in the case of a central office line with polarity reversal, a central office line reversal detecting means is applied, and in the case of a central office line without polarity reversal, such as a PBX extension line, a ringing tone signal detecting means or the like is applied.
