Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic dialing device in which it is possible to externally specify whether each party that can be called by automatic dialing is outside the city or within the city.

An automatic dialing device generally has a storage device that stores the telephone number of a specific party, and sends out a dial signal by selecting the telephone number of a desired party from the storage device in response to a party selection signal.

Here, in the conventional automatic dialing device, the telephone number is stored in the storage device from the area code or local code depending on whether the dialing device is outside the area or within the city. , the method was to read the memory contents from the beginning. In other words, the contents of the storage device were used to distinguish whether each caller was outside or within the city, so even if the phone number of the same caller was stored, the stored content may differ depending on the location of the automatic dialing device. It may or may not include. This means that even if the telephone number of the other party is determined, the contents of the storage device cannot be determined unless the installation location of the device is determined.
The task of setting a telephone number during manufacturing or installation adjustment becomes extremely complicated. Particularly when setting telephone numbers on-site, such as by installing and replacing diodes or key entry, there is a high risk of errors occurring. The present invention has been made to deal with such problems, and is capable of storing telephone numbers by providing a means for easily specifying from the outside whether each caller is outside the city or within the city for the installation location. To provide an automatic dialing device capable of storing information starting from the area code, regardless of whether the other party is outside the city or within the city. The present invention will be explained in detail below with reference to Examples.

The figure shows an embodiment in which the present invention is applied to a private network control device that is directly connected to the Kameme public corporation line. 1 is a partner selection signal line, 2 is a CRQ signal line, 3 is a multiplexer, 4 is an outside-city designation circuit newly provided in the present invention,
It has a built-in plurality of switches S corresponding to each partner.

For example, these switches S are set to the ON state when the corresponding party is outside the city where the present device is installed, and are set to the OFF state when the corresponding party is within the city. The multiplexer 3 determines the state of the switch S corresponding to the partner selection signal and outputs it. 5 is a next number counter, 6 is a storage device that stores the telephone numbers of each party, and all telephone numbers are stored starting from the area code.

7 is a call control circuit, 8 is a dial pulse start circuit, 9 is a clock circuit that generates a clock pulse of lopps or 2 ps, 10 is a dial pulse counter, 1
1 is a minimum pause circuit, 12 is a dial pulse generation circuit, and 13 is a line control section.

Table 1 is an example of the storage format of the storage device 6,
Table 2 shows a portion of the stored contents. Table 1 2 This example is for a case where there are 16 or less partner stations, and each station is allocated a storage capacity for one trip.

Therefore, the storage device 6 has, for example, 256 digits (1 line x 1
6 stations) PROM is used. Note that the partner selection signal “0”
”, “1”, “2”, ... “F” are expressed as 16 falcon digital codes, and a fixed value (“0” is used in this example) is added to this code and is stored in the storage device 6. This is the first address.Explaining the contents of each address using Table 2, first, address 0 of @ is a numerical value indicating the address of the first digit where a telephone number is stored.Also, 1 of ■ The area code is in the ~2 address, the telephone number consisting of the local area code and subscriber number is in the @3 to 9 addresses, and the end code of the telephone number is in the A address of the ■.
Here, "0" is used) are stored respectively. However, Table 2 is for the case where the area code is 2 digits and the city code is 3 digits; in other cases, the positions of ■, ■, and ■ will be shifted sequentially. Note that ■ is an empty address. Next, the operation will be specifically explained.

Now, when a partner selection signal is input to line 1 and a CRQ (call request) signal is input to line 2, the next number counter 5 first receives the CRQ signal.
Set by a signal. On the other hand, a state determination signal of the switch S corresponding to the partner selection signal in the designation circuit 4 is sent from the multiplexer 3 to the next number counter 5. The partner selection signal is also supplied to the storage device 6, whereby the leading address within the storage device 6 is designated. For example, the partner selection signal is “0”
In this case, "00'' is specified as the first address. If the status determination signal output from multiplexer 3 at this time is a signal indicating that the switch is ON, the area code is required, so the next address is The content of the number counter 5 becomes 11, and the content of the storage device 6 becomes the first address "0".
The address is displayed starting from the address after 0'1 and dialed in order. That is, the contents of each address read from the storage device 6 are preset in the dial pulse counter. The dial Subaru counter 0 is counted down by clock pulses from the clock circuit 9 until its contents reach "0". The contents of the dial pulse counter 10 are “
0'', the minimum pause circuit 11 operates, sends a signal to the next number counter 5 after a certain delay time, and increments the contents of the next number counter 5 by one. The contents of the address are listed,
Thereafter, telephone numbers are discussed in the same manner until the end code is detected. The dial pulse generation circuit 12 generates a dial pulse every time the dial Subaru counter 0 counts down by one, and this dial pulse is sent to the line 14 via the line control section 13. On the other hand, when the start address in the storage device 6 is specified by the partner selection signal, if the status determination signal output from the multiplexer 3 is a signal indicating switch OFF, the area code is not required. The number counter 5 presets the value of address "0" in the storage device 6 at the timing of the first signal sent from the minimum pause circuit 11.

As a result, the contents of the storage device 6 are read out and dialed starting from an address that is shifted by the value of the "0" address from the first address. As a result of the above operations, for example, in the example in Table 2, if an area code is required, the telephone number "03-446-1111" is dialed, and if an area code is not required, the telephone number "03-446-1111" is dialed.
46-1111" is dialed.

In the figure, the call control circuit 7 confirms that there is no incoming call when the CRQ signal is received, operates the dial pulse start circuit 8 for starting the dial Subaru counter 10 and the minimum pause circuit 11, and also operates the line control unit. It functions to control 13. In the automatic dialing device of the present invention configured as described above, all telephone numbers including area codes are stored in the storage device 6.

For example, in the example shown in Table 2, the telephone number corresponding to the partner selection signal "0" in the storage device 6 is "03-446-11".
11'', and the telephone number corresponding to the partner selection signal ``1'' is ``0462-23-1111''. When an automatic dialing device as described above having such memory contents is installed, for example, within the Tokyo 2 dollar rate, one of the switches S in the out-of-town/inside-city selection circuit 4 corresponds to the destination selection signal "0". The switch is kept OFF, and the switch corresponding to the partner selection signal "1" is kept ON. If you do it this way,
When the partner selection signal “0” is input, “446-11” is input.
11J and when the other party selection signal "1" is input, "0462-23-1111" is automatically dialed. When installing a similar device in Yokohama, for example, the contents of the storage device 6 should be the same, and the switches corresponding to the partner selection signals "0" and "1" in the outside-city designation circuit 4 should both be turned on. By keeping the
When "0" is input, "03-446-1111" is dialed, and when the other party selection signal "1" is input, "0462-23-1111" is dialed.

As described above, according to the present invention, each party is provided with a specification means for specifying whether the automatic dialing device is installed in an out-of-town area or within the city, and thereby the telephone number in the storage device can be changed from the area code to the area code. Since it is decided whether to read out or derive from the local area code, setting the telephone number is extremely easy.

In other words, with the present invention, all telephone numbers in the storage device can be stored starting from the area code, so the contents of the storage device can be determined as long as the other party is decided, and a simple switch operation can be performed depending on the installation location. By simply specifying whether the dial is outside or within the city, dialing can be performed normally. Therefore, not only does the work of setting a telephone number become easier, but also the work errors can be reduced. In addition, in cases where the number of partner stations is limited to a few locations (number of centers), such as with data entry terminals, it is also possible to use PROM or MASKROM as a storage device for telephone numbers, in which case the telephone number cannot be changed. However, it can be easily resolved by simply replacing the IC. Furthermore, as a storage device for telephone numbers, devices with fixed or semi-fixed storage contents, such as those based on magnetism, contacts, or printed circuit boards, can be practically used.

In the above embodiment, a switch was used to specify whether the destination is outside the city or within the city, but instead, an electronic storage element such as a RAM or ROM is used, and each partner is stored in the city. Exactly the same effect can be obtained by storing information of "1" and "0" indicating outside or inside the city.

Further, in the embodiment described above, the dial signal is transmitted in the form of a dial pulse, but it goes without saying that the present invention can be similarly applied to a system in which the dial signal is transmitted in the form of a multi-frequency signal.
