Abstract

PURPOSE:To prevent a judgement of absence from being made after a ring-back tone is heard several times on a calling telephone side by inhibiting the transmission of a message tone to the calling telephone set until a coupling switch is turned on after the starting of the operation of a message tone generator. CONSTITUTION:A terminating telephone set B is provided with a hold switch 12, which is turned on when the message tone generator 16 provided to an originating telephone set C starts operating. Consequently, once an incoming signal detector 13 detects the dialing of the calling telephone set A, the hold switch 12' of the originating telephone set C turns on and a dial signal generator 14 calls a transfer destination telephone set D. When an answer detector 15 detects an answer from the opposite telephone set, the message tone generator 16 starts operating to turn on the switch 12 of a terminating telephone set B. Consequently, tone transmission to the calling telephone set A is stopped until the coupling switch 4 is closed. When the coupling switch 4 is closed thereafter, a telephone call is allowed between the calling telephone set A and transfer destination telephone set D.

Description

DETAILED DESCRIPTION OF THE INVENTION An object of the present invention is to provide a telephone transfer device that can quickly transfer telephone calls.

Conventional telephone transfer devices have a ringing tone of 7 when the incoming telephone is called.
Since the device was connected only after ringing ~8 times, it was so slow that it could be mistaken as being absent and disconnected, so the present invention connects as early as 4 to 5 times. It was designed so that

The present invention provides a holding switch 12 connected to a receiving telephone line 5 and a calling telephone line 5, which maintains both telephone lines 5. A holding switch 12' connected to line 5' and a contact 17.1 electrically connecting both telephone lines 5.5'.
7, a dialing signal generator 14 for calling a forwarding telephone, an incoming signal detector 13 connected to the called telephone line 5, and a response detector connected to the calling telephone line 5''. 15, and a message tone generator 16 connected to the line 5° to distinguish between forwarding and direct transmission, the holding switch 12 of the telephone transfer device 3 is connected to the message tone generator 16 connected to the line 5°, The telephone transfer device is configured to be turned ON in conjunction with the telephone receiver 16, so that transfers can be made quickly.

Figure 1 shows a known example, where l is an office, 2 is a branch office, and A
is the calling telephone (calling telephone), B is the receiving telephone (receiving telephone), C is the calling telephone, D is the destination telephone, and 5 is the receiving telephone from calling telephone A. Telephone line leading to B, 3
is a telephone transfer device connected to the receiving telephone B and the calling telephone C; 5 is the calling side telephone line from the calling telephone C to the forwarding destination telephone; and 4 is a device installed in the telephone transferring device. Automatically activated by coupling switch 4.

In Figure 1, when a person who was in the office went to the local office 2 and then received a call at the office, the call was transferred to the local office 2! It will be bad.

In Fig. 1, the call can be transferred to the local office 2. When a call is placed from the calling telephone A to the receiving telephone B, the telephone transfer machine 3 detects this and transfers the call to the calling telephone C. By maintaining the telephone line so that it can send calls and transmitting the pre-stored dial number of the forwarding destination telephone of the branch office 2 through the telephone line of the transmitting telephone C, The forwarding destination telephone equipment is called through the line 5'. When the handset of the called forwarding destination telephone is picked up, the telephone transfer 41!3 detects that the handset has been picked up, holds the telephone line of the receiving telephone B so that it can send a call, and The automatic connection switch 4 provided in the transfer device 3 is automatically closed to connect the telephone lines of the incoming telephone set B and the outgoing telephone set C, and the telephone lines of the incoming telephone set B and the outgoing telephone set C are connected. This allows direct communication between the calling telephone device A and the transfer destination telephone device.

Furthermore, when the call between the calling telephone set A and the forwarding telephone set ends and the calling telephone set A or the forwarding telephone set is disconnected, the telephone transfer machine 3 detects this and transfers the call to the receiving telephone set B and the calling telephone set. At the same time as releasing the hold on the telephone line of C, the connection switch 4 is opened to release the connection between the telephone lines of the incoming telephone set B and the calling telephone set C, and the incoming telephone set B is placed on standby for the next call. I have to.

The internal structure and operation of the above-mentioned conventional telephone transfer device 3 are as shown in FIG.
Terminal 11' connected to the called telephone line 5 via
11' is a terminal connected to the calling telephone line 5' via the calling telephone C, 12 is a hold switch that holds the telephone line of the receiving telephone B so that it can send and receive calls, and 12' is the calling telephone C. 13 is an incoming signal detector connected to the incoming telephone line 5 on the incoming telephone B side, 14 is a dial signal generator, 15 is a response detector, and 16 is a message tone generator. , 17.17 are contacts of the coupling switch 4 which couples the telephone lines of the incoming telephone B and the outgoing telephone C via the capacitor 18.

The dial signal generator 14. An answer detector 15 and a message tone generator 16 are connected to the originating telephone line 5' via terminals 11', 11'. The holding switch 12 and the combination switch 4 are configured to be turned on in conjunction with each other.

In the above-mentioned known example, when calling telephone A calls incoming telephone B, a ringing bell signal is sent to incoming telephone B from the telephone office, and this signal is detected by incoming signal detector 13. Then, the holding switch 12' of the originating telephone C is closed to hold the telephone line of the originating telephone C so that it can send and receive calls, and the dial signal generator 14 is used to store the telephone number of the forwarding telephone in advance. When the handset of the forwarding destination telephone is picked up, this is detected by the response detector 15 and the forwarding destination telephone is notified. In order to distinguish whether the call is a forwarded call or a direct call, the message tone generator 16 operates to make the person who answered the forwarded call hear a signal tone or voice for several seconds. Tell them that this call is a forwarded call.

Message tone generator 16. When the operation is finished, the telephone transfer device 3 closes the holding switch 12 of the receiving telephone B to hold the telephone line of the receiving telephone B, and also closes the combining switch 4.
Close contacts 17 and 17 to connect incoming telephone B and outgoing telephone C.
The telephone lines of the telephone A and the forwarding destination telephone are connected so that a direct call can be made between the telephone A and the transfer destination telephone.

Here, after the operation of the message tone generator 16 is completed, the signal tone of the message tone generator 16 is used to hold the telephone line of the receiving telephone B and to connect the telephone lines of the receiving telephone B and the calling telephone C. Alternatively, this is to prevent the voice from being heard by the calling telephone device A even if the voice can be heard by the transfer destination telephone device.

That is, the operation of the conventional telephone transfer device is as follows: (a) Detection port of the incoming call signal detector 13 Turn on the holding switch 12 on the calling telephone C side C) Operation of the dial signal generator 14 (2) Detection of the response detector 15 Home message tone generation 2, the hold switch 12 of the receiving telephone B and the combination switch 4 were turned on.

However, in the conventional telephone transfer device, the holding operation of the telephone line of the receiving telephone B, that is, the turning ON of the holding switch 12 is the last of the series of operations (usually 4 to 4 seconds after the message tone generator 16 is activated). (usually 6 seconds), at least seven ringing tones are required from the time the ring signal arrives at the receiving telephone B until the telephone line of the receiving telephone B is held. However, since the incoming telephone number B was not held for a long time, I often ended up canceling the call, thinking that I was not at home.

However, even if the hold switch 12 is turned on at the same time as the message tone generator 16 is activated, no problem will occur in the telephone transfer system.
The message tone generator 16 is configured to be turned on at the same time as the message tone generator 16 is activated, which is approximately 4 to 6 seconds (of course, these time values are -).

The following is a diagram illustrating the telephone transfer device according to the present invention.
1 and 11 are terminals connected to the receiving side telephone line 5 via the receiving telephone B, respectively, and 11' and 11゛ are the terminals connected to the calling telephone C.
12 is a holding switch that holds the telephone line of the receiving telephone B so that it can send and receive calls, and 12' is a holding switch that similarly holds the telephone line of the calling telephone C. 13 is an incoming signal detector connected to the terminating telephone line 5 on the terminating telephone B side; 14 is a dial signal generator; 15 is a response detector; 16 is a message tone generator; 17.17 is a capacitor 18 This is the contact point of the coupling switch 4 that connects the telephone lines of the incoming telephone set B and the calling telephone set C via the terminal. The dial signal generator 14, response detector 15 and message tone generator 16 are connected to the telephone line 5' via the terminal 11'11'. The holding switch 12 and the message tone generator 16
is configured to turn ON in conjunction with each other.

In the above, after the incoming call signal detector 13 of the receiving telephone B operates, the hold switch 12' of the calling telephone C is closed, the dial signal generator 14 is activated, and the handset of the forwarding telephone is picked up. The response detector 15 detects this and operates the message tone generator 16.
Although it is the same as the telephone transfer device shown in the figure, in the telephone transfer device according to the present invention, the message tone generator 16
At the same time as the start of operation, the hold switch 12 of the receiving telephone B is turned on (a controller for turning on the hold switch 12 is naturally provided, but a well-known control mechanism can be used, so the illustration is omitted). be). At this time, the person making the call using calling telephone A stops ringing and recognizes that he has picked up the handset of receiving telephone B, but in reality, contacts 17 and 17 of combination switch 4 are not yet connected. I can't hear the message tone. On the other hand, the person who answers the transfer destination telephone can hear a message tone that cannot be heard on the calling telephone set A, and can know that this is the one that has been transferred.

After that, after the message tone continues for several seconds, the contact 17 of the switch 4 connects the lines of the incoming telephone B and the outgoing telephone C.
．． 17, it becomes possible to talk between the calling telephone A and the transfer destination telephone.

In addition, when the call between the calling telephone set A and the transfer destination telephone set is finished and the handset of the calling telephone set A or the transfer destination telephone set is put down, the hold switch of the receiving telephone set B and the calling telephone set C is 12.
12' is opened and the hold on both telephone lines is released, and
The contacts 17 and 17 of the coupling switch 4 are also opened, and the line between the receiving telephone B and the calling telephone C is also decoupled.In the conventional telephone transfer device, the ringing tone that rings the receiving telephone is heard seven to eight times. Since the connection was made only after the phone rang, there were times when it was so slow that it was mistakenly assumed that I was away, and the phone was disconnected.
