Abstract

PURPOSE:To simplify the operation when recalling is applied to a trunk line by providing a means for storing a telephone number of a called party when an extension telephone set makes a call to the trunk line and a means for identifying the retransmission to the said called party in a private branch of automatic exchange. CONSTITUTION:In making a call from extension telephone sets 1.1-1.n to trunk lines 5.1-5.m respectively, a central storage device 7 counts a dial pulse transferred from an extension to trunk line trunks 4.1-4.m via a digital trunk 8 and stores it. Furthermore, a called party of the trunk line trunk 5.m side is busy unfortunately and a caller makes recalling to the same trunk line, then the caller does not hook on the handset of the extension telephone set 1.n but hooks off and dials a prescribed specific number. Moreover, a dial pulse transmitter 9 is driven by information stored in the central storage device 7 to transmit the same dial pulse to the trunk line 5.m thereby calling back the called party.

When making a call to each of the m office lines 5.1 to 5.m, the dial pulse is transmitted to each of the n subscriber circuits 2.1 to 2.
n, under the control of a central control unit, via digital trunks, by central office line trunks 4.1 to 4.m,
It was sent to each station line. However, the dial pulse information is not stored in the central storage device, but only information on which extension is making a call and which central office trunk is used, as shown in Table 1.

ループをつくり、再発信状態にする必要があった。1-1 That is, the dial pulse was simply transferred to a predetermined office line via the office line trunk or office line trunk. Therefore, once dialed, the information is not left anywhere, so even if a call is to be made again, the only option is to send a dial pulse again from the extension telephone. If you want to make a re-call, hang up the handset, release the troublesome central office line trunk loop, pick up the handset again, and then
It was necessary to create a loop and put it into a state of re-transmission.

When a call is made from an extension telephone to a central office line, the dial information sent to the first central office line is counted and stored in the storage means, so that the call can be made even if the called party is unfortunately busy. After the hooking operation, the caller simply dials a special number without hanging up the handset, uses the re-dialing identification means to identify the re-dialing, terminates the call, and then dials the call again after a predetermined period of time. A simple central office line in an automatic private branch exchange, wherein the dialing information is sent from the storing means to the central office line so as to be in a calling state, thereby making it possible to return to a calling state and re-calling to the same central office line. This is a re-transmission method.

発信方式でもある。The present invention also provides an automatic private branch telephone exchange, which includes a storage means for storing the telephone number of a called party when a call is made from an extension telephone to a central office line, and an identification means for identifying a re-call to the same called party. When making a call from an extension telephone to a central office line, the dialing information to be sent to the central office line is temporarily stored in the storage means, and if the called party is unfortunately busy, the calling party can temporarily hang up the telephone. Then, after a predetermined period of time, the caller picks up the handset again and dials a special number, and the identification means identifies the call as a re-call and returns the call to the call state. It is also a simple central office line re-transmission system characterized in that the dialing information is sent from the storage means to the central office line to re-transmit to the same central office line.

前記のような簡易な操作で再発信が可能となる。For example, unfortunately, central line 5. If the called party on the central office line of m is busy and the calling party wishes to call again to the same central office line, the calling party does not hang up the handset of extension telephone 1 or n.
Perform a hooking operation and dial a certain predetermined special number. This operation is retrieved by the central controller 6 through the digital trunk 8 and identifies that the caller wishes to call again. After that, the central control device 6
- Immediately release the central office line side loop of the central office line trunk 4.m currently in use, and after a certain period of time, the central office line trunk 4.
A station line side loop of m is generated and the transmitting state is established again. Furthermore, based on the information in Table 2 stored in the central storage device 7 (:), the dial pulse sending device 9 is driven, and the same dial pulse is sent to the central office line 5.m side to call the called party. By implementing the present invention as described above, when making a re-call to a central office line, the user can make a re-call to a central office line without having to hang up the handset or dialing all the same numbers.
Re-transmission is possible with the simple operation described above.

可能であるということは明白である。In the above implementation, a simple operation is performed and the call is made again immediately after the central office line is in a busy state, but since the dialing information is stored in the memory, it is difficult to call again even when the central office line is in a busy state. Obviously, it is also possible to hang up and wait until the phone is out, then pick up the handset and dial a special number to make the call again.

〈発明の効果〉 本発明は以上説明したように、局線へのダイヤル情報を
