However, due to improvements in operability in recent years, the call key 10 pressed when making a call to a central office line automatically acquires an empty central office line, and the numeric keypad By pressing , it is now possible to automatically capture a vacant office line and send a dial to the office line.

That is, when the user of the button telephone terminal 7 presses a speed dial using the speed key 11 and the numeric keypad 9, the speed dial is notified to the terminal management means 5 through the terminal control means 6.

The terminal management means 5 recognizes the central office line call request from the user based on the contents of the speed dial. Thereafter, it requests the central office line management means 4 to search for and acquire a vacant central office line.

If there is a vacant office line, the office line management stage 4 issues an instruction to the office line control stage 3 to seize the office line, and notifies the terminal management stage 5 of the captured station line. The terminal management means 5 displays on the station line key/lamp l3 of each terminal, through the terminal control stage 6, that the station line 2 has been captured.

If there is no vacant office line, the terminal management stage 5, which has been notified of this by the office line management means 4, notifies the terminal user of this information through the terminal control stage 6 through a busy tone or the like.

Problems to be Solved by the Invention However, with the above-mentioned conventional button telephone device, the user of the button telephone terminal usually does not check for a vacant office line when making a call. , the shortcut operation you entered will be invalidated, and after hearing the busy tone, you will have to wait for the central office line to become free and perform the same operation again. The problem was that I needed to find it.

The present invention solves these conventional problems,
Another object of the present invention is to provide an excellent single-button telephone device that allows easy re-operation when there is no vacant office line.

Means for Solving the Problems In order to achieve the above object, the present invention provides a button telephone main device with a means for storing dialed numbers by each button telephone terminal, and when there is no vacant office line, the destination telephone number or abbreviated number is stored. The number is stored, and when the central office line becomes vacant, the destination telephone number or abbreviated number is retrieved from the storage means and made a call.

Effects Therefore, according to the invention. Even if there are no vacant central office lines at the time of the initial call operation, the destination phone number or abbreviated number resulting from that dialing operation is stored, so that if the central office line becomes vacant thereafter, certain predetermined operations can be performed. The call is made by retrieving the destination telephone number and abbreviated number from the storage means, and there is no need to look up the destination's telephone number and abbreviated number once again at the time of the re-dialing operation, improving the efficiency of the outgoing call operation.

Embodiment FIG. 1 shows the configuration of an embodiment of the present invention. In FIG. 1, a key telephone main device 21 has a plurality of central office lines 22
and a large number of button telephone terminals 27 are connected.

In this button telephone main device 21, 23 is a station line control stage 24 for performing dialing, incoming call detection, etc.
2, and issues control instructions to the station line control stage 23, or conversely, notifies the terminal management means 25 of information from the station line control stage 23. The management means 25 manages the button telephone terminal 27.

26 recognizes off-hook/on-hook of the handset from the button telephone terminal 27 and press information of each key, and informs the terminal management 1000 steps 25 and sends information to the terminal user according to instructions from the terminal management means 25. The provided terminal control means 33 is a final dial storage means that stores the last dialed number of each button telephone terminal under the control of the terminal management 1000 steps 25.

The button telephone terminal 27 also includes a handset 28, a numeric keypad 29, an abbreviation key 30 for performing abbreviation operations, a resend key 3 for sending out the final dial dialed last time, and a reservation key for the central office line 22. It has a reservation key 32 for making reservations.

Next, the operation of the above embodiment will be explained.

When the button telephone terminal 27 is in standby mode, the shortened dialing operation (
Normally, after pressing the shortcut key 30, the numeric keypad 29 is pressed for about 2 digits), the terminal management 100-stage 25 of the button telephone main device 21 receives the key information from the button telephone terminal 27 through the terminal control 100-stage 26. , examines the contents of the corresponding speed dial, and if there is a request to make a call to the central office line, requests the central office line management means 24 to seize a vacant central office line, and if there is a vacant central office line, acquires the central office line and sends out the speed dial. Then, this abbreviated dial is stored in the final dial storage stage 33.

However, if there is no vacant office line, the final dial storage means 33 is used to store the speed dial. In this way, when the central office line becomes vacant, if the resend key 31 is pressed after the central telephone terminal 27 captures the central office line, the number to which the previous call failed will be sent.

Further, if there is no vacant office line (busy sound), press the reservation key 32 of the button telephone terminal 27 to put it in standby mode, and the terminal management means 25 will tell the office line management means 24,
Executes a system for reserving central office lines.

That is, when a vacant office line occurs, the office line management section 24 notifies the terminal management means 25, and the terminal management section 25 calls the reserved terminal. When the called button telephone terminal 27 raises the /% end set 28, the central office line 22 is captured, and by pressing the resend key 31,
It is possible to dial again to a party to whom the call was unsuccessful due to lack of vacant office lines the previous time using the calling telephone number or abbreviated number reproduced from the last dial memory 1,000 stages 33.

Effects of the Invention As is clear from the above embodiments, the present invention stores the calling operation even when there is no free office line and the call fails, and when the office line becomes free and an opportunity to make a call occurs, Since the memorized outgoing phone number and abbreviated number are read out and made, there is no need to check the dial or abbreviated number of the person to call each time you make a re-dialing, which has the effect of improving the efficiency of the outgoing call operation. .
