Abstract

PROBLEM TO BE SOLVED: To allow a terminal telephone set to surely receive transfer service by allowing the telephone set to eliminate an additional dial signal and to dial only a required dial number even when an NCC adaptor or the like adds an NCC connection number to the dial signal after hooking. SOLUTION: A hooking pulse reception section 11 monitors a hooking pulse from a terminal telephone set 3. A dial monitor section 12 monitors a dial signal from the telephone set 3 after the arrival of the hooking pulse, and when an NCC header number and a signal succeeding thereto are sent from the telephone set 3, the monitor section 12 eliminates only the NCC header number. A dial number transmission reception section 13 sends a remaining dial number that results from eliminating the NCC header number from the dial signal coming from the telephone set to a station exchange. Thus, the telephone set 3 surely receives a transfer service after speech by Trio phone (R) and Voice warp (R) even on a telephone line in contract with the NCC.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for rejecting an NCC header number under certain conditions and transmitting a subsequent dial signal (number) excluding the NCC header number.

[0002]

2. Description of the Related Art A trio phone and a voice warp, which are provided by NTT (registered trademark) by hooking activation, perform a hooking operation during an incoming call to hold an incoming call and hold the incoming call. This is a three-party call service in which a third party makes a dial call and a third party answers, and a transfer service after a response.

On the other hand, at present, in addition to NTT, three companies, namely, Japan Telecom (registered trademark), Daini Denden (registered trademark), and Japan High Speed Communication (registered trademark), have newly established Shindenden (registered trademark) (NC).
C) provides telephone communication services. And
These NCCs are prefixed with 0088,007
The communication service provided with the NCC header number of 7,0070 added through its own line is provided. This header is automatically added by the NCC adapter.

[0004]

However, NCC companies judge that the hooking pulse for a time longer than a certain value should be reapplied. Therefore, when a toll call service such as an NCC number is added to a service line of a triphone or a voice warp and used, a hooking operation is performed during a call, and it is determined that the NCC number adding device (adapter or the like) is reset. Erroneous connection occurs due to additional dialing of the NCC number connection number. Therefore, at present N
Lines receiving CC services cannot receive triophone or voice warp services.

[0005]

In order to solve the problem, the present inventor has proposed that when a hooking signal is transmitted from a telephone, the remaining dial signal is transmitted by removing the NCC header number in the subsequent dial transmission. The present invention has been completed. That is, after hooking, the dial is NCC
Even if an additional device such as an adapter sends an additional dial with an NCC connection number (NCC header number), the device of the present invention deletes the additional dial and allows only necessary dial numbers to be received and transmitted. . Although the device of the present invention is connected to the outside (office side) of the NCC adapter, its function can be incorporated in the office exchange itself.
Also, NC between the private branch exchange on the terminal equipment side and the terminal telephone
If a C adapter is installed, it can be incorporated into this private branch exchange.

[0006] The apparatus of the present invention comprises a hooking pulse receiving unit for receiving a hooking pulse from a terminal telephone, a dial monitoring unit for monitoring a dial signal from the terminal telephone,
A dial number transmitting and receiving unit, which detects that a hooking pulse has been transmitted, and, if a NCC header number is subsequently transmitted, issues a command to remove the NCC header number from the transmitted dial signal and transmit the same; It is composed of a control unit that controls the entire device. When the apparatus of the present invention is incorporated outside the NCC adapter (office side), the apparatus of the present invention removes the NCC header number and sends out the remaining dial numbers as they are to the central office exchange. When incorporated in the central office exchange, the central office deletes the header part and returns to normal exchange.

[0007]

Next, the present invention will be described in detail with reference to the drawings. FIG. 1 shows an example in which the device 1 of the present invention is incorporated into a telephone line 2. In this example, an NCC adapter 5 is incorporated between the terminal telephone 3 and the private branch exchange 4. The device 1 of the present invention is located between the private branch exchange 4 and the NCC adapter 5 (state A), outside the private branch exchange 4 (the central office 6
Side: state C). Alternatively, it may be built in the private branch exchange 4 (state B) or the central office 6 (state D).

FIG. 2 shows a configuration of the apparatus 1 of the present invention. The apparatus 1 of the present invention comprises a hooking pulse receiving section 11, a dial monitoring section 12, a dial number sending and receiving section 13, and a control section 14. Then, hooking during a call is monitored by the hooking pulse receiving unit 11, and the presence or absence of hooking from the terminal phone 3 is monitored. The dial signal from the terminal telephone 3 after the hooking is received by the dial monitoring unit 12 and when the NCC header number and the subsequent signal are transmitted from the terminal telephone 3, only the NCC header number is deleted and the dial number is deleted. Sending and receiving unit 13
Is a system in which the outgoing dial from the terminal telephone 3 removes the NCC header number.

[0016]

As described above, according to the present invention,
Triophone service and exchange after answering can be reliably performed from the telephone line contracted with NCC, and the effective use of telephone is further promoted.
