Abstract

PURPOSE:To improve the efficiency for transfer of incoming telephone by changing automatically the memory of the telephone station side in accordance with an operation for the change of an abbreviated dial. CONSTITUTION:When a telephone A calls a telephone B, a telephone C is hooked off. Then an abbreviated dial signal stored previously is delivered from a telephone C, and a telephone D is called. A telephone E calls the telephone C and a loop circuit is formed between telephones E and C. An RAM 8 is set at the side of the telephone C with an abbreviated dial setting operation signal given from the telephone E. The telephone C is hooked off again after releasing once the loop circuit after storage, and the abbreviated dial setting operation signal which is stored thereafter is transmitted to a telephone station to update the registration of the telephone station side.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic telephone transfer device that transfers calls received from an unspecified number of customers to a specific location.

In the past, many of these types of automatic forwarding devices in Japan used speed dials, but speed dials are only available from telephones that can make speed dials in order to use telephone office equipment, such as C (described below). It was not possible to change new speed dials. However, if the original owner calls telephone B from an external telephone E, automatically puts C into a dial tone receiving state, and sends a speed dial number from E, then the speed dial number of the central office will be dialed via said C. It has the possibility of storing or erasing the memory device. This means that the patent application filed by the same applicant
4-130482, pages 3 to 4 of the publication.

The present invention is a modification of the prior art as described above.1. (This is accomplished by using the telephone B.)

The structural function of the present invention will be explained below.

In the figure, A is the telephone of the unspecified caller, B is the incoming telephone of this device, C is the outgoing telephone of this device, and D is the incoming telephone of this device.
is the transfer destination telephone, and E is a touch-tone telephone for changing the transfer destination. Also, LT is a line transformer, 1
2 is an OR circuit, 3 is a transistor, and Y-4, which is the load of transistor 4, is a loop relay, and contacts y4-1. y4-2. y4-3
has.

Further, one is a single-commonity timer circuit, and the other is a dual tone decoder for decoding the tone sent from telephone E to telephone C, and the decoded tone is output as 4 bits. Further, 6 is a rectifying and smoothing circuit, 7 is a counter that performs a numeric value based on the output of the rectifying and smoothing circuit, C is a clock terminal, R is a reset terminal, and 0 is an output terminal, for example, 4.
Consists of bits. Reference numeral 8 denotes a memory (RAM) having a predetermined number of 4-bit bytes, in which the output of the tone decoder 5 is stored, and is output from OUT when changing the registration of speed dial to a station, which will be described later. Further, 2 is a Pu'er tone oscillation circuit that oscillates a dual tone by once outputting from the memory, 10 is a delay circuit of several seconds,
The tank is an inverter, the shell is a Noritsubu Frog circuit, and the clothes are an AND circuit.

This figure shows a conventional transfer circuit, that is, when a call is received from phone A to phone B, phone C sends a speed dial of r*00J in dual tone to call the caller.
The basic circuit in which telephones A and D go into a talking state when the telephone goes off-hook, and when either telephone A or D goes off-hook, the talking state is canceled and the transport circuit is restored, is not shown because it is not directly related.

Next, the operation of the present invention will be specifically explained.

When the owner of this device calls telephone C from external telephone E, terminal 2 of OR circuit l is set to H1 through ringing circuit 1, terminal 3 is set to H, transistor 3 is turned on, and load relay Y is turned on.
-4 is energized. Here, contact y4-1 of relay Y-4.
y4-2. Since y4-3 is closed, contact y4-1. y4
-2 forms a loop via the line transformer LT, telephones E and C enter a talking state, timer A registers through contact y4-3, and relay Y-4 is held for, for example, one minute. When the transistor above is turned on, the reset under the counter is released via its collector. Here you can operate the speed dial settings using the PsoShiphone on telephone E. Suppose that when a call is received on phone A, it will be forwarded to phone E, and the phone number of phone E is 42.
If it is 1-2266, call rO*o042 from phone E.
Send 12266J codes one after another. The above code is converted into a binary number by a tone decoder via a line transformer LT and written into a memory. It should be noted that when the aforementioned transistor 1 is turned on, the flip-flop is inverted via the inverter 2, and the memory 8 is in a low state due to its Q output.

Furthermore, each time the above code is sent one digit at a time by the tone of the button 7 on, the counter 7 is incremented by 1 by the output of the rectifying and smoothing circuit 6, and the entire code above is stored in the memory while changing the address of the memory 1. Get into it.

Now, when the sending of the code from telephone E is finished, go on-hook. On the device side, when timer A times off, transistor 1 turns off and relay Y-4 recovers.
The loop on phone C side is opened. Transistor 3 above
When the counter is turned off, the bottom of the counter is reset, and at the same time, the terminal 2 of the AND circuit 13 is set to H1 via the delay circuit W. Since the terminal 1 is set to H due to the inversion of the flip-flop μ, the terminal 3 is also set to H, which is the output of the OR circuit. Terminal 1.
Transistor 3 is turned on via 3 and relay Y-4
is energized to put telephone C in an off-hook state. At the same time, the reset under the counter is released by turning on transistor 3, and the flip-flop and tube 1 are turned on through the inverter.
2 is inverted, the Q terminal becomes H and the memories are read out.

With this, the first 1 byte of memory "0" is OUT.
Upon output from the terminal, the dual tone oscillation circuit 9 oscillates the corresponding tone and sends it to the line via the line transformer LT. When the tone is sent out for a predetermined period of time,
Assuming that the tone transmission is stopped inside the dual tone oscillator circuit 9 and a minimum pause is created, the counter l is incremented by 1 through the rectifier and smoothing circuit due to this minimum pause, and then the second byte from the fifth memory is output"*"
The corresponding tone is oscillated from the dual tone oscillator circuit, and the code rO*004212266 is generated in the same manner.
When the oscillation of " is completed, telephone E is called from the station.

As described above, in the present invention, the defects of the prior art described above are modified, and after forming a loop circuit by directly calling the telephone C from the outside (E), it is possible to change the speed dial using the conventional pushphone. If you do this, once it is stored in the memory, it will automatically loop again and the tone will be automatically sent to the central office to change the speed dial, change the memory of the central office equipment to which phone C belongs, and wait for a certain period of time. This makes it possible to wait on an automatic transfer device for a newly registered number after the elapse of time, and the practical effect of this type of device has been greatly improved. This is what you will apply for.
