Abstract

PURPOSE:To decrease the operating time of a telephone line by outputting dial information corresponding to an abbreviated number registered in advance to the telephone line by an abbreviated dial operation from a telephone set in the case of calling and talking. CONSTITUTION:The abbreviated dial registration of a key telephone set, the trunk line acquisition, the output of content of abbreviated dial translation and the signal type switching are all given to a CPU 27 via a data transmission/ reception circuit 28 and detected. Further, the registration content of the abbreviated dialing and the signal kind of the trunk line are stored in a RAM 26 in advance. Then the trunk line acquisition is operated from the key telephone set 21, a trunk line connection circuit 24 is operated to form a trunk line channel 22. When the abbreviated dial is operated, the translated content corresponding to the said abbreviated dial number is led out of the RAM 26 and dial information corresponding to the translated content is outputted from a dial information output circuit 23 by the designation signal kind.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a speed dial service system, and particularly to a system in which dial information can be sent by speed dialing even from a telephone in use.

(Prior Art) The conventional speed dial system is used only as a means for calling the called party's subscriber telephone after making a call to the central office line.

(Problems to be Solved by the Invention) In recent years, in general subscriber telephone lines, dial information is used as a means of transmitting data in a central office line call state, and a so-called end system that transmits the above data to the other party by outputting a dial signal has been developed. Two-end service is in place.

When performing the above end-to-end service with conventional telephone equipment, the abbreviated type pftt service cannot be used, so the user must press the dial button one digit at a time from the telephone, and the manual operation involving many digits requires the use of a central office line. The problem was that it took a long time.

The purpose of the present invention is to register not only the subscriber telephone number of the called party, which has been adopted in the past, but also the dialing information as data as described above, and to register the translated dialing information corresponding to the abbreviated number by a speed dial operation. The purpose of the present invention is to provide an abbreviated dialing service system that allows the output of

(Means for Solving the Problems) For the above purpose, the present invention provides that when a shortcut operation from a telephone is detected, the central office line is disconnected regardless of whether the telephone is in a calling state or in a conversation state. Depending on whether or not the abbreviated dial translation is captured, a dial signal of PB or DP designated by the speed dial translation is output.

(Embodiment) FIG. 1 is a schematic configuration diagram of an embodiment in which the present invention is implemented in a button telephone device, and FIG. 2 is a flowchart showing the operation of the embodiment.

In Fig. 1, 2C1 is the main device, 21 is a button telephone, 22 is a central office line communication path, 23 is a dial information output circuit, 24 is a central office line connection circuit, and 25I is a main unit for realizing this system. 26 is a RAM that can register and store speed dials, 27 is a CPU that controls peripheral circuits according to the program, 28 is a button telephone, and a data transmission/reception circuit that exchanges data between the main devices. show.

Button operations from the button telephone 21 are input to the CPU 27 via the data transmission/reception circuit 28 . Therefore, all operations such as registering the shortcut cell on the button telephone, acquiring the central office line, outputting the contents of the shortened tie 1 full translation, and switching the signal line are carried out by the CPU 27 via the data transmission/reception circuit 28.
is input and bridged.

Further, the registered contents of the speed dial and the signal line of the office line are stored in the RAM 25 in advance.

Here, a central office line capture operation is performed from the button telephone 21,
The office line connection circuit 24 operates and the "C office line communication path 22 is formed. Then, when the speed dial operation is further performed,
The translation corresponding to the speed dial number is stored in RAM 2.
The dial information output circuit 23 outputs dial information corresponding to the above-mentioned translated content based on the designated ft number type extracted from 6.

Generally, when transmitting data using a central office line, the data is often predetermined information.

Examples include a bank account number, a PIN number, a calling party's subscriber telephone number for international communication callbacks, a called party's subscriber's telephone number in the other country, etc.

It would be possible to register the above-mentioned dial information in advance by operating a key telephone, and to display the existing translation information on the acquired station line by shortening the line if necessary.

Note that the office line is set in advance as either a PB line or a DP line. Therefore, if you simply operate the speed dial, the signal will be output using the signal set above. Furthermore, if it is necessary to switch the signal line for output, the signal switching operation can be performed immediately before the speed dial operation.

The above practical example is an example in which the present invention is implemented in a button 'I' stuffing device, but even in a standalone stuffing machine that employs a computer system, such as a so-called multi-function telephone, the CPU of the telephone, The present invention can be implemented using RAM or the like. Further, although the telephone line is a telephone line on the central office line in the above embodiment, it may be a private line, for example, and may be generally considered to be a telephone line.

(Effects) The present invention is not limited to the conventional shortening time t'L operation to call the called party's subscriber telephone after making a call, but also the shortening time t'L operation can be performed at any time while the telephone line is being acquired. Since the data transmission time in end-to-end communication can be set to the minimum necessary time, it has the advantage that the usage time of the telephone line can be further reduced.
