Description

[Detailed description of the invention] Part 1 The present invention relates to a speed dial memory changing device.

Conventional push-button telephones are equipped with a speed dial function that abbreviates about 20 telephone numbers and stores them in a storage device within the central telephone office. The following two methods are known for storing a new abbreviated number in this storage device or for changing an already stored abbreviated number.

The first method is to directly operate the telephone, and this is a well-known technique that is used everywhere. The second method is to change the telephone number using a telephone other than the telephone set, which is described in Japanese Patent Application Laid-open No. 137762/1983 filed by the present applicant.

This method is explained in detail as shown in Fig. 2, and A
is a telephone in the office, B is another telephone installed in the same office, C is a telephone with a speed dial function when out and about, D
is a speed dial storage or changing device, and E is a telephone office, then the storage device of the telephone office E that governs telephone A can only be changed by telephone A, but can be changed only by telephone A and another telephone B. A telephone B connected to the telephone B via a speed dial storage or changing device is called by a telephone C having a speed dial function at another location such as a remote location.

When telephone B detects a call from telephone C, which is outside the home, telephone B automatically holds telephone A in a lifted state and connects telephone A to telephone station E. After opening,
Telephone B transfers the call from Telephone C to Telephone A.

Then, various signals from telephone C are transferred to telephone A via telephone B. At this time, since telephone A has an open line with telephone station E, various signals from telephone C are transmitted to telephone station E. Telephone office E receives a call from telephone C, which is outside the home, etc., but the signal is input via telephone A, so it is processed as a signal from telephone A.

Therefore, if a change signal is input from telephone C at the outside location to the storage device of central office E via telephone B and telephone A, the storage device can be changed freely.

In the above-mentioned known example, in order to change the stored contents of telephone A from telephone C while away from home, at least telephone B and a speed dial storage or changing device are required. .

The present invention eliminates the need for the telephone B and the speed dial storage or changing device, and allows the telephone 2 having the short dial function to change or create a new speed dial number from the calling telephone L. Memory element 1 for temporarily storing input signals
4, and a P-B tone generating section 20 that converts the contents stored in the memory element 14 into a P-B tone and transmits it to the central telephone station 3, and the telephone This is a speed dial memory changing device configured so that the contents of the speed dial function of the device 2 can be changed or a new input can be made.

Therefore, one embodiment of the present invention will be described with reference to the drawings. In FIG. 3, l is a telephone set for calling an unspecified number of people, for example, a telephone set installed in an office outside the home. Reference numeral 2 indicates the telephone set having a speed dial function, and 3 indicates the central telephone station 3 of the telephone set 2.

1 and 4 show various devices attached to the telephone 2, 4 is a terminal connected to the telephone line connecting the telephone 2 and the central telephone office 3, 5 is a relay contact, and 6 is a call telephone. an incoming call detection unit that detects a call signal from the telephone device 1 to the telephone device 2;
7 is a connection terminal.

8 is a hybrid transformer that electrically maintains the line between the calling telephone 1 and the telephone 2; 9 is an amplifier; IO is an encoder that converts the input signal from the calling telephone 1 into a binary number;
1 and 12 are connection terminals.

In FIG. 4, 13 is a central processing element, 14 is a storage element that temporarily stores the input signal from the calling telephone 1, 15 is a code storage element that stores the code of the user of the telephone 2, and 16
is an input element, and terminal 1 is connected to the connection terminal 7.
7. It has a terminal 18 and the like connected to the connection terminal 11.

19 is an output element, 20 is a P-B)-n generating section,
21 is a terminal connected to the connection terminal 12, and 22 is a part of a relay that operates the relay contact 5.

Next, we will discuss the effect.

When it becomes necessary to change the abbreviated memory contents of the telephone 2 in a place far away from the telephone 2, the telephone 1 that can generate the P-B)-tone sends a control phone to the telephone 2. Make a call through station 3. Then, a call signal from the call telephone 1 is inputted from the terminal 4, the incoming call detection section 6 detects the incoming call, and the relay part 22 is activated via the input element 16, the central processing element 13, and the output element 19. , the relay contact 5 is turned ON, and the calling telephone 1 and the telephone 2 are connected.
line is connected.Next, when the code number registered in advance in the code memory element 15 is inputted from the calling telephone device l, the input signal is amplified by the amplifier 9, converted to a binary signal by the encoder 10, and input It is input to the central processing element 13 via the element 16 and compared with the registered code number, and when it is confirmed that the user is the user of the telephone 2, the system waits for an input to change the short memory contents of the telephone 2. become a state.

When the desired contents are inputted from the calling telephone 1 into the telephone 2 through normal operation, this change input signal is temporarily stored in the memory 14 via the amplifier 9, the encoder 1O, and the input element 16 in the same manner as described above. be remembered. When the input operation on the call phone 1 is completed and the call phone 1 is turned off, the relay part 22
turns OFF and relay contact 5 closes.

After confirming that the call telephone has been disconnected, wait for a certain period of time, for example 10
After seconds have elapsed, the central processing element 13 is actuated, actuating the relay part 22 and turning on the relay contact 5. Then, the central telephone office 3 enters a state of waiting for an input from the telephone set 2. The central processing element 13 reads the changed input signal stored in the storage element 14, converts it into a P@B tone by the P/B tone generation section 20 via the output element 19, and outputs the signal to the terminal 21,
A call is made to the central telephone office 3 through the connection terminal 12. Therefore, in order to input the signal from the telephone 2, the central telephone office 3 allows the modification of the short memory contents for the telephone 2,
