Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic redialing device for redialing to an individual group having a plurality of subscriber terminals having individual lines.

[0002]

2. Description of the Related Art As a redialing method of redialing to an individual group having a plurality of subscriber terminals each having such an individual line, a redial function provided in a telephone is usually utilized.

The redial function is to store a dial number, which is a line number input by dialing immediately before, in a memory inside the telephone and to store it in the memory by pressing a redial button provided in the telephone. The redial is performed based on the dialed number.

Therefore, according to the redial function, by pressing the redial button without inputting the dialed number one by one, it is possible to make a call to the partner terminal associated with the immediately preceding dialed number by a very simple operation. You can

However, when a call is made to an individual group of subscriber terminals having a plurality of individual lines and the line is blocked due to busy line, it is repeated many times in anticipation that the blockage of the line is released. You have to redial.

Therefore, it is conceivable to make a call to another line in the individual group, but it is very troublesome to dial the line numbers of the other lines one by one.

However, many of the line numbers related to the individual lines in such an individual group have, for example, different last digits, and in view of such a situation, the telephone has a reset call function. There are things I have prepared for.

With the reset call function, the line number up to the last digit is stored in advance in the memory inside the telephone, and the reset call button provided on the telephone is pressed and the last digit digit number is input. As a result, it is possible to make a call to another line in the individual group with a simple input operation.

[0009]

However, according to the reset call function as the conventional redialing method described above,
When making a call to another line of an individual group having a plurality of individual lines, there was a problem that Tang had to input a reset call button and a last digit digit number provided on the telephone.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an automatic re-transmitting device that significantly improves the operability when transmitting to another line in the same group. To provide.

[0011]

In order to achieve the above object, an automatic re-transmitting device of the present invention is provided with group identification data for identifying a plurality of subscriber terminals each having an individual line as an individual group and within the individual group. Line data storage means for storing line data indicating a line number relating to the subscriber terminal, and transmission data storage means for storing transmission data corresponding to the line number of the other party involved in the transmission when the transmission is received, When the blockage of the line related to the outgoing data is detected, the line data corresponding to the outgoing data is searched from the line data storage unit, the group identification data corresponding to the searched line data is searched, and the same group is searched. And a control means for transmitting based on other line data related to the identification data.

[0012]

With such a configuration, according to the automatic repeater of the present invention, when a plurality of individual lines are included in the same group, even if the blockage of a certain line is detected, it is possible to connect to other lines in the same group. Since the outgoing call is executed by the above, the operability at the time of outgoing call to the other line in the same group can be remarkably improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An automatic repeater device of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an outline of an electronic private branch exchange to which an automatic repeater device of the present invention is applied.

In FIG. 1, an electronic private branch exchange 1 controls connection between a public line network 2 and a plurality of telephones 3.
A memory 4 which is a line data storage means for storing group identification data for identifying a plurality of subscriber terminals each having an individual line as an individual group and line data indicating a line number relating to the subscriber terminals in the individual group; When receiving a call, a memory buffer 5 which is a call data storage means for temporarily storing call data corresponding to the line number of the other party involved in the call, and an extension circuit (LC) for controlling and monitoring the input / output of the telephone 3. ) 6 and the public network 2
It has a central office trunk (TRK) 7 for monitoring the input and output of the system and a CPU 8 for controlling the entire electronic private branch exchange 1. Incidentally, the control means according to claim 1 is the extension circuit 6,
It corresponds to the office line trunk 7 and the CPU 8.

Next, the operation of the electronic private branch exchange 1 to which the automatic repeater device of the present invention is applied will be described. FIG. 2 is a flow chart showing main processing operations of the CPU 8 in the electronic private branch exchange 1 to which the automatic redialing apparatus of the present invention is applied.

In FIG. 2, the CPU 8 stores in advance in the memory 4 a subscriber number which is group identification data for identifying a plurality of subscriber terminals each having an individual line as an individual group and a dial number which the individual group has. (Step S11). Next, when the off-hook and dial number input of the telephone 3 are detected through the extension circuit 6 (step S12), the input dial number is temporarily stored in the memory buffer 5 as outgoing data (step S13), It is determined whether or not the partner terminal of the dial number is busy via the trunk line trunk 7 (step S14). The dial number temporarily stored in the memory buffer 5 in step S12 is stored until a call is established or the user goes on hook of the telephone 3.

If the other party terminal is busy, it is determined whether the dial number of the other party terminal, that is, the dial number corresponding to the outgoing data stored in the memory buffer 5 is stored in the memory 4. Judgment (step S1
5). If there is a corresponding dial number in the memory 4, the subscriber number associated with the dial number is searched to determine whether or not there is the same subscriber number, that is, a dial number that is not performing a calling operation in the same group. It is determined (step S16). If there is a dial number that is not performing the calling operation, the dial number that is not performing the calling operation is read from the memory 4, and the station line trunk 7 is caused to perform the calling operation based on the read dial number. (Step S17), the process proceeds to step S14.

If the other party's terminal is not busy in step S14, a call is started by the response of the other party's terminal (step S18), and on-hook is detected via the extension circuit 6 (step S19). , And ends the processing operation.

If there is no dial number corresponding to the outgoing call data stored in the memory buffer 5 in step S15 in the memory 4, or in step S16, a dialing number that has not been called in the same group. If not, the process proceeds to step S19.

In step S16, the processing operation is repeatedly executed until there is no dial number in the memory 4 for which the transmission operation is not executed.

According to the electronic private branch exchange 1 of the above embodiment,
If there are multiple individual lines in the same group and the other terminal with a dial number is busy, the call is automatically sent based on the other dial numbers in the same group. It is possible to significantly improve the operability when making a call to another line in the group.

Further, in the above embodiment, the automatic repeater was applied to the electronic private branch exchange 1, but the telephone line 3 stores the group identification data and the line data in advance. Needless to say, if the means is provided, it can be applied to the telephone 3.

[0023]

According to the automatic re-transmitting device of the present invention configured as described above, when a plurality of individual lines are provided in the same group, even if the blockage of a certain line is detected, Since the call is made to the other line, the operability when making a call to the other line in the same group can be significantly improved.
