DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key telephone apparatus,
In particular, the present invention relates to a key telephone apparatus having a hold function and an automatic response function.

[0002]

2. Description of the Related Art Conventionally, a key telephone apparatus of this type transmits a response message to an external line received by an extension telephone according to a preset time from an extension telephone or a state such as presence or absence. It has become.

[0003]

The conventional key telephone apparatus described above has a configuration in which a response message is transmitted to an incoming call to the extension telephone according to a preset state from the extension telephone to automatically respond. However, since it does not have the function of automatically responding to an external line received by another extension telephone by operation from an extension telephone or putting it on hold, it is mainly accepted to respond to the line received at the office etc. If only one person is receiving calls at the same time, and one or more other external lines arrive at the same time, or when the receptionist is on an outside line or extension call If the receptionist cannot immediately respond to the incoming outside line, as in the case, the outside line that is arriving using the hold function or the automatic answering function is sent out and a temporary response message is sent out. There is a drawback that it is not possible to keep the state.

[0004]

A key telephone apparatus according to the present invention is a key telephone apparatus having a main unit for accommodating a plurality of external lines and a plurality of extension telephones, wherein the main unit is set in advance when the external line is received. Message sending section for sending a message to the user, a hold tone sending section for sending a hold tone in response to a hold setting signal from the extension of the called party, and control means for controlling the response message sending section and the hold tone sending section. And the control means is configured such that when the plurality of extension telephones are capable of receiving an incoming call in a single state, when the plurality of external lines are in the receiving state at one time, or when the plurality of extension telephones can receive the incoming call. When the extension telephone is in a call and the other one or more external lines are in a call receiving state, upon receiving a predetermined automatic response setting signal from the extension telephone capable of accepting the call, Controlling the response message sending unit to send a response message to all the external lines in the receiving state, and then controlling the hold sound sending unit to send the holding tone to put all the external lines in the receiving state into the holding state. It has a control unit for causing

[0005]

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

In FIG. 1, a key telephone apparatus according to the present embodiment comprises a plurality of external lines 20 and an extension telephone 4 from a central office exchange 30.
0-1 and 40-2 to 40-n. In the main unit 10, each of the external line interface units 1-1, 1-2 to 1-m detects an incoming call of each of the external lines 20, performs a capture operation, and sends a detection signal to the control unit 6 when an incoming call is received. Talk line switch 2 is extension 5
The connection between the outside line 20 and the response message sending unit 4 and the hold sound sending unit 5 is disconnected. The telephone interface unit 3 is connected to the extension telephones 40-1 and 40-2 to 40-n and the communication path switch unit 2, and the extension telephones 40-1 and 40-4.
A signal accompanying the operation of 0-2 to 40-n is sent to the control unit 6. The response message sending unit 4 sends a response message to the outside line 20 via the communication line switch unit 2 according to the control signal from the control unit 6, and the hold tone sending unit 5 similarly sends the control message to the control unit 6.
A hold tone is transmitted to the outside line 20 via the communication line switch unit 2 in response to a control signal from the telephone line. The control unit 6 receives signals from the external line interface units 1-1, 1-2 to 1-m and the telephone interface unit 3 to control the external line interface unit 1-1-1.
1, 1-2 to 1-m, the communication path switch unit 2, the response message transmission unit 4, and the hold sound transmission unit 5.

Next, the operation of this embodiment when one extension telephone can receive an outside line will be described.

When only the extension telephone 40-1 has a user and is ready to accept an outside line, when a plurality of outside lines 20 are in a call-in state at one time, or when another outside line or extension is in a call, the other outside line 20 is in a call state. When a plurality of external lines 20 are in a call receiving state, the external line interface units 1-1, 1-2 to 1-m send an incoming call detection signal to the control unit 6 after detecting the incoming call. When the user of the extension telephone 40-1 performs an operation from the extension telephone 40-1 to automatically respond to the incoming external line 20 and put it on hold, the telephone interface unit 3
Sends an automatic response setting signal corresponding to the operation of the extension telephone 40-1 to the control unit 6.

The control unit 6 having received the automatic answer setting signal controls the outside line interface units 1-1, 1-2 to 1-m to automatically capture the outside line 20 in the incoming call state, and 2. Control the response message sending section 4 to send a response message to the outside line 20 automatically captured.

After the end of the response message, the control unit 6 controls the call path switch unit 2 and the holding tone sending unit 5 again to send the holding tone to each of the external lines 20 in the receiving state.
Keep 0 pending.

[0012]

As described above, according to the present invention, the main unit is provided with a response message transmitting unit, a hold tone transmitting unit, and a control unit for controlling these by a signal from the extension telephone, so that a plurality of units can be provided at once. When an outside line of a telephone is in a receiving state, or when one or more other outside lines are in a receiving state during an outside line or an extension call, it is mainly possible to respond to a line received at an office or the like. If only one person is on the phone, the main unit automatically responds to the incoming external line by operating the receptionist's extension telephone and puts the caller on hold. There is an effect that can be kept.
