Abstract

PURPOSE:To devise the titled equipment to require only one connection train by detecting a reply signal from a 1st connection destination, receiving a multifrequency signal of a transfer destination telephone number and sending the transfer destination telephone number to a 2nd connection destination. CONSTITUTION:A transfer telephone system 11 for a caller and a transfer telephone system 13 for a transfer sender are used, and the telephone call transfer telephone system 13 for the transfer sender is set in the transfer state, then the transfer telephone number coming from the 1st connection destination 5 is replied automatically, the connection to the 1st connection destination 5 is interrupted and its transfer destination telephone number is sent again to the 2nd connection destination 9. Thus, the connection train for two calls is not required, only one train is enough, and no special amplifier is required and the telephone number of the transfer destination for the transfer connection can be confirmed by the caller.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a transfer telephone device having a transfer telephone connection function in a telephone network.

[Conventional technology]

FIG. 4 is a block diagram showing a conventional transfer telephone device.

In the figure, 1 is an originating telephone, 2 is a local exchange, 3 is an outgoing trunk, 4 is an incoming trunk, 5 is a local exchange, 6 is a transfer telephone device, T is an outgoing trunk, 8 is an incoming trunk, and 9 is an incoming trunk. 10 is a transfer destination telephone.

Next, the operation of the transfer telephone device having the above configuration will be explained. First, when the calling telephone 1 dials the number of the forwarding telephone 10, this dial signal is transmitted through the local exchange 2 - outgoing trunk 3 - person trunk 4 - local exchange 5 and then connected to the receiving terminal 6a of the forwarding telephone device 6. Ru. Therefore, the forwarding telephone device 6 uses its calling terminal 6b and dials the number of the forwarding destination telephone 100.This forwarding telephone 6 - calling terminal 6b - local exchange 5 - outgoing trunk T - person trunk 8
- connected to the forwarding destination telephone 10 via the local exchange 9;

Therefore, when the transfer destination telephone 10 responds, when the transfer telephone device 6 detects this, the transfer telephone device 6 switches the incoming call terminal 6 and the outgoing call terminal 6b through. As a result, the caller from the originating telephone 10 can talk to the transfer destination telephone 10.

[Problem that the invention seeks to solve]

The conventional transfer telephone device described above has two terminals, an incoming terminal and an outgoing terminal, and performs a transfer connection through a connection path for two calls in a normal telephone connection.

Therefore, the transfer telephone device requires a special amplifier to ensure the transmission level. Furthermore, there is the disadvantage that even if a long-distance call is made, the caller may actually be connected back to the caller's vicinity due to a transfer connection, which may incur extremely high call charges.

[Means for solving problems]

The forwarding telephone device of the present invention uses a forwarding telephone device for a caller and a forwarding telephone device for a transfer source, and by setting the forwarding telephone device for a forwarding source to a forwarding state, Automatically answer incoming calls from your forwarding number,
The connection to the first connection destination is cut off, and the forwarding destination telephone number is retransmitted to the second connection destination.

[Effect]

This invention does not require a connection train for two calls, but only one connection train, does not require a special amplifier, and allows the caller to confirm the telephone number of the transfer destination for the transfer connection.

〔Example〕

FIG. 1 is a four-dimensional diagram showing an embodiment of the transfer telephone device according to the present invention. In the figure, reference numeral 11 indicates a transfer telephone device for the caller whose detailed circuit configuration is shown in FIG. 2, 12 indicates an outgoing trunk, and 13 indicates a transfer telephone device for the transfer source whose detailed circuit configuration is shown in FIG. 3. , 14 is the telephone of the transfer destination.

In the caller transfer telephone device 11 shown in FIG. 2, 15 is a receiver, 16 is a transmitter, 17 is a telephone circuit network,
18 is a speech synthesis circuit for synthesizing the transfer connection message and the transfer destination number to be notified to the caller; 19 is a multi-frequency signal (push button signal) receiving circuit; 20 is a network control section; 21 is the speech synthesis circuit 18; This is a control section that controls the multi-frequency signal receiving circuit 19 and the network control section 20. Further, in the transfer telephone device 13 for the transfer source shown in FIG. 3, 22 is a transfer destination number sending circuit, 23 is an automatic response circuit, and 24 is a control circuit for controlling the transfer destination number sending circuit 22 and the automatic response circuit 23. , 25 is a switch for setting the transfer state, 26 is a telephone m-way network, 27 is a receiver, and 28 is a transmitter.

Next, the operation of the transfer telephone device having the above configuration will be explained. First, when the caller dials the telephone number of the forwarding telephone device 13 for the transfer source using the forwarding telephone device 11 for the caller, the forwarding telephone device 1F for the caller is transferred to the local exchange 2.
- Outgoing trunk 3 - Person trunk 4 - Connected via local exchange 5 to a transfer telephone device 13 for the transfer source. Therefore, when the network control unit 20 of the transfer telephone device 13 for the transfer source detects a response from the first connection destination, the multi-frequency signal receiving circuit 19
receives the forwarding destination telephone number and sends the number of the telephone 14 for voice synthesis forwarding. Then, the caller receives the telephone number of the forwarding destination telephone 14 through the forwarding telephone device 11 for the caller, and the first connection to the forwarding telephone device 13 for the forwarding source is disconnected. The telephone number of the previous telephone 14 is called again and a second connection is made, but at this time, the transfer telephone device 13 calls the voice synthesis circuit 18 as described above.
You can confirm that the caller is being forwarded to the caller, you can also hear the forwarding destination's phone number through voice synthesis, and you can confirm where the caller has been forwarded to.

Then, the caller makes the call again and confirms the dial tone from the exchange, or sends the telephone number received above to the transfer destination telephone 14 after a sufficient period of time for the dial tone to be output. In this case, either a dial pulse or a push button signal can be used as the selection signal to be sent. Due to this, the caller's transfer telephone device 11
- Local exchange 2 - Outgoing trunk 12 - -Person trunk 8
- Local exchange 9 - Connected to the transfer destination telephone 14 and connected to the transfer destination. In the above-described embodiment, it is of course possible to combine the circuits shown in FIGS. 2 and 3 to configure a circuit that can be used for either the sender or the transfer source. In addition, although Figures 2 and 3 show the circuit configuration for transfer integrated with the telephone, the function for controlling transfer is installed separately from the telephone circuit (circuit network). It is of course possible to do so.

〔Effect of the invention〕

As explained in detail above, according to the transfer telephone device according to the present invention, by using the transfer telephone device for the caller and the transfer telephone device for the transfer source, it is not necessary to use a multi-connection train for two calls. It only requires one train, does not require any special amplifiers, and allows the caller to confirm the forwarding number if necessary, meaning that the forwarding connection is made completely transparent to the caller. It has the advantage of being able to provide call forwarding connections without any hassle.
