Abstract

PURPOSE:To attain easily and accurately the addition of an abbreviated dial function and to use plural botton telephone sets in common by connecting an information processing circuit formed separately between the button telephone sets and an exchange. CONSTITUTION:The abbreviated dial of the telephone set 1 is inputted to a discriminating processing circuit 7 constituting an information processing circuit 2, and the circuit 7 discriminates and processes which kind of the abbreviated dialing is performed from which telephone set to which trunk line. The result is transmitted to a circuit 8 including a microprocessor as a parallel data in 4-bit. The circuit 8 drives a driving circuit 11 to change over a relay contact 6, only the normal dial information corresponding to the abbreviated dial is read from a memory 9 and transmitted to a telephone exchange 3 via a contact 6 and a data line 5. Thus, the exchange 3 is operated according to the said information, which is transmitted to a required trunk line 4.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a button telephone device having a speed dial function.

Conventional configurations and their problems In general, in button telephone devices, the speed dial function is often implemented in each telephone or as an initial function in the exchange itself. In some cases, it was not possible to use the same speed dial in common on different telephones, and the software development as a whole was extremely difficult because it was implemented as a first function in the exchange itself.
There was a problem in that each model had to be developed separately.Objective of the InventionThe present invention is intended to eliminate the above-mentioned conventional drawbacks, and to develop a system for one or more telephones arbitrarily and in a large capacity. It is an object of the present invention to provide a button telephone device having an excellent speed dial function that allows connection.

1. Structure of the Invention The present invention includes means for receiving speed dial information from a key telephone and determining what kind of speed dial has been made from which telephone to which office line, and by the output of this means.
A means for reading dial information according to the speed dial information from a separately provided memory and transmitting the dial information to the telephone exchange is provided separately from the telephone and the telephone exchange, and each means is provided separately from the telephone and the telephone exchange. It is configured so that it can be arbitrarily connected between a telephone and a telephone exchange.

DESCRIPTION OF EMBODIMENTS FIG. 1 is a schematic diagram of an embodiment of a button telephone device according to the present invention. 2 is a button telephone, 2 is an information processing circuit for inputting and processing dial information from telephone 1, 3 is a telephone exchange, 4 is a central office line, 5 is a data line, and 6 is a relay contact.

FIG. 2 is a concrete block diagram of the above information processing circuit. In the figure, 7 inputs the dialing information from the button telephone 1, and processes the processing to determine which telephone has dialed what kind of dial to which office line. A discrimination processing circuit 8 is a circuit including a microprocessor that inputs the output of the discrimination processing circuit 7 and outputs information stored in the memory 9 in accordance with the input; 10 is connected between the circuit 8 and the memory 9; 11 is a relay drive circuit driven by the output of the circuit 10, and 12 is a transistor that drives the relay 13.

In the above embodiment, it is assumed that a normal dialing is now performed on the telephone set 1. In this case, the discrimination processing circuit 7 discriminates the above-mentioned dial information as a normal dial, and transmits the output to the circuit 8. Therefore, in this case, circuit 8
does not drive the relay drive circuit 11, and the relay contact 6-1 remains in the state shown in the figure. Therefore, the above-mentioned dial information is directly transmitted to the telephone exchange 3 through the switch relay contact 6 and the data line 5, and then transmitted to the central office line 4 via the telephone exchange 3.

Assume that you have now performed speed dialing on telephone 1. That is, suppose that, for example, **NN (N=0 to 9) is dialed as an abbreviated dialing operation of this telephone device.

When speed dialing is performed, this dial information is first input to the discrimination processing circuit 7 that constitutes the information processing circuit 2, and here, based on the above-mentioned dial information, the speed dial is determined from which telephone to which central office line. Process to determine whether it has been done. The result is then transmitted as 4-bit parallel data to a circuit 8 including a microprocessor. A circuit 8 including a microprocessor receives the data and drives a relay drive circuit 11 to switch the relay contact 6, and also reads normal dial information corresponding to the speed dial from a separately provided memory 9. is transmitted to the telephone exchange 3 via the relay contact 6 and the data line 5.

Therefore, the telephone exchange 3 operates according to the above information and transmits the above information to the new central office line 4.

As described above, the above embodiment has the advantage that the speed dial function can be operated easily and accurately by the operation of the information processing circuit 2.

The information processing circuit 2 is connected to the key telephone 1 and the switchboard 3.
Since it is formed separately and connected to the terminal, it can be used as a telephone at any time, and it can also be used in common with several button telephones, making it practical. This is extremely advantageous.

In the embodiment, a case has been described in which only a speed dial function is added, but it is also possible to add an oscillation regulation function to a specific dial. That is, in this case, the dial information for which outgoing calls should be restricted is stored in the memory 9, and when the dial information that needs to be restricted outgoing calls is input to the signal processing device 7, and its output is input to the circuit 8 including the microprocessor. , it is configured so that the end-of-call data is output to the output terminal of the circuit 8 in comparison with the dial information stored in the memory 9 that is desired to restrict outgoing calls, and by the function of the circuit 8, the relay drive circuit 1 is The relay contact 6 may be switched to transmit the call termination data to the telephone exchange 3 via the relay contact 6 and the data line 5. In this way, the telephone exchange 3 immediately stops transmitting the dial information upon receiving the call termination data, so that the oscillation of the transmission of the dial information whose oscillation is to be restricted can be accurately restricted in advance.

Effects of the Invention As is clear from the above embodiments, the present invention includes a discrimination processing circuit that receives abbreviated dial information from a button telephone and discriminates which telephone has made what kind of abbreviated dial to the central office line, and A circuit including a microprocessor that receives the output of the circuit, reads out normal dialing information corresponding to the speed dial information from a separately provided memory, and transmits this to the telephone exchange is formed separately from the button telephone and the telephone exchange, and optionally It is configured so that it can be connected to the above-mentioned button telephone and the above-mentioned telephone exchange, and the above-mentioned ゛t1
] By connecting a separate processing circuit, a circuit containing the microprocessor described in (h) to the above-mentioned button telephone and the above-mentioned telephone exchange, it is possible to easily and accurately add a speed dial function, and furthermore, the discrimination processing circuit, Each circuit containing a microprocessor can be used in common for several button telephones, which is extremely advantageous in practice.
