Abstract

PURPOSE:To eliminate the need for a transfer party to care about the holding of an external line by providing a means which uses information from an extension telephone set holding an external line and transfers a holding alarm tone to other optional extension telephone set. CONSTITUTION:Plural extension telephone sets 2-1-2-n and a master set 1 are provided, and the master set 1 is provided with holding means 11, 14 holding a busy external line of plural telephone sets and holding alarm tone transmission means 11, 15 and 16 is sending a holding alarm tone to the extension telephone sets 2-1-2-n holding the external line when an external line is holding for a prescribed time or over. Moreover, holding alarm tone transfer means 11 and 14 sending a holding alarm tone to the holding of the external line to other extension telephone sets 2-1-2-n through the input of the preset information from the extension telephone sets 2-1-2-n holding the external line are provided to the master set 1. Thus, it is not required for the transfer party to care about the holding of the external line.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a key telephone device, and more particularly to a key telephone device having a function of transmitting an outside call hold alarm sound.

[Conventional technology]

Conventionally, this type of pushbutton telephone device has a function of putting an in-progress outside call on hold and, if the call remains on hold for more than a preset period of time, it has a function of sending a hold warning sound to the extension telephone that has put the outside call on hold. Was.

[Problem to be solved by the invention]

In the above-mentioned conventional key telephone device, if an extension telephone that holds an outside call continues to be on hold for a preset period of time, it sends out a hold alarm sound, so that the outside call is transferred to another extension telephone. In such cases, the outside line is temporarily put on hold, the user of the other extension telephone is verbally told to capture the outside line, and after the verbal transfer is made, the transferred person answers the outside line within a preset period of time. Otherwise, a hold alarm will sound on the transferer's extension telephone, and the transferer will have to take action.

[Means to solve the problem]

The button telephone device of the present invention includes a plurality of extension telephones, and a main device accommodating an outside line and the plurality of extension telephones,
a holding means for putting on hold the external lines in progress of the plurality of telephones in the main device; and a holding alarm for sending a holding alarm sound to the extension telephone holding the external line if the external line is kept on hold for a predetermined period of time or more. In the button telephone device having a sound sending means, the hold alarm tone for the hold of the outside line is transmitted to the other extension phone by inputting preset information from the extension phone holding the outside line to the main device. It has a hold alarm sound transfer means.

〔Example〕

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

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

In FIG. 1, this embodiment has extension telephones 2-1 and 2-1.
~2-m~2-n, and multiple outside line and extension telephones 2-1
．． 2-11.2-m to 2-n.

The main device 1 has an extension telephone 2-1. ~2-g, ~2-m, ~
2-n, an outside line interface circuit 13 that interfaces with a plurality of outside lines, a switch network 14 that connects the extension lines with the outside lines and communication paths between the extension lines, and a timer 15 that counts the hold time, etc. and sound source 1 that generates hold music, hold alarm sound, etc.
6 and a central processing section 11 that controls the inside of the main device 1.

Next, the operation of this embodiment will be explained.

Now, when the extension telephone 2-m is in the middle of an external call and the predetermined operation of pressing the hold button (not shown) of the extension telephone 2-m is canceled in order to put the current external call on hold, this information is sent from the extension telephone 2-m to the central processing unit 11 via the telephone interface circuit 12.

The central processing unit 11 controls the switch network 14 to put the outside line on hold, causes the sound source 16 to output a hold tone, and starts the timer 15 to start counting the hold time.

On the other hand, the user of extension telephone 2-m verbally tells the user of extension telephone 2-1 to answer the outside call that has been put on hold, and then presses a preset function button on extension telephone 2-m. Dial the extension phone number 2-1.

Information from a series of these extension telephones 2-m is sent to the central processing unit 11 via the telephone interface circuit 12.
It is stored in a storage unit (not shown) in the central processing unit 11.

When the timer 15 finishes counting the preset period of time, the central processing unit 11 checks whether the user of the extension telephone 2-1 is not responding to the on-hold external line, and then the central processing unit 11 stores the number in the internal storage unit. Based on the data, the switch network 14 is controlled to connect the extension telephone 2 via the telephone interface circuit 12.
-g is connected to the sound source 16, and the sound source 16 sends a hold alarm sound to the extension telephone 2-1.

〔Effect of the invention〕

As explained above, the present invention has means for transmitting a hold alarm sound to any other extension telephone based on information from the extension telephone that has put the outside call on hold, thereby verbally transmitting the transfer of the outside call to a preset constant level. Since the hold alarm sound can be transferred to the extension telephone of the transferred party after a certain period of time, the transferee can continue working without worrying about the external line being held.
