FIG. 1 shows the relationship between a number of main line selection devices 100 and a host computer (HC) 200 as a source of various data. In this figure, each line selection device 100 connected to a telephone set 100i of each individual can communicate with a telephone set 300, 400 having a representative number via a telephone line and a central office 500. HC 200 is a telephone set having two representative numbers. A large number of telephones 300i, 400i respectively connected to the telephones 300, 400 are connected, and the on / off hooks of the telephones 300i, 400i are controlled under the conditions described later, and data is exchanged via the telephones after the off-hook.

The HC 200 is provided with a DLP unit 201 as shown in FIG.
The DLP unit 201 has a large number of telephones 300i, 400i
And the telephone line (LIN) connected to each of the telephones 300i and 400i.
E) and a number of DLP boards 201i interposed therebetween.
Further, the HC 200 has a workstation (WS) 202 that controls each DLP board 200i, and a keyboard 203 and a display device (CRT) 204 connected to the workstation 202. 600
Is an external data storage device (for example, a hard disk device)
And connect to the workstation 202 in the HC 200.

The DLP board 201i is as shown in FIG. 4, where 210 is a CPU, 211 is a ROM storing a program described later, 212 is a RAM, 213 is a CPU 210 and a workstation.
This is an interface (I / F) that connects to 202. The telephone line (LINE) 215 from the telephone having the representative number is connected to the winding on one side of the telephone 300i (400i) or the line transformer 216 via the contact of the relay 214.

An input terminal of a photocoupler (PC) 219 for receiving a call signal from the exchange is connected to the telephone line 215, and an output signal of the photocoupler 219 receiving the call signal is input to a ringer 220, and an output of the ringer 220 is output. The signal is input to the CPU 210, and upon receiving the signal, the CPU 210 switches the relay 214 to the line transformer 216 as necessary (described later).

By switching the relay 214 to the line transformer 216, the winding of one side of the line transformer 216 is loaded on the telephone line 215, and the telephone 300i connected to the telephone line 215 is off-hook.

In the HC200 having the above configuration, the dialer 217 is

For example, the data in the data storage device 600 is temporarily stored in the RAM 212 in a predetermined DLP board 201i via the workstation 202, and the stored data is transmitted as a DTMF signal from the dialer 217 under the control of the CPU 210.

Further, the HC 200 is, for example, a telephone 300 of one representative number.

[Automatic Selection] Here, an operation of automatically selecting one of a plurality of telephone lines will be described.

First, when the telephone is on-hook, relay 3 is a
It is connected to the contact side, so that a signal from the exchange side is supplied to the telephone. When the telephone is called in the on-hook state, a ringing signal is input to the dial pulse or dial tone signal input terminal of the CPU 6, so that even if the telephone is off-hook in that state, the CPU 6
Does not switch the relay 3 and the contact a remains connected.

When the telephone is off-hook in a state of no ringing, the impedance between the pair of telephone terminals 2 changes from high impedance to low impedance, and an off-hook detection signal from the photocoupler 7 is input to the CPU 6 via the amplifiers 8 and 9. With this input, the CPU 6 sends a signal to the relay driver 20, and the relay 3 switches to the contact b side. As a result, the telephone and the office line are separated from each other, and a voltage stabilized by the stabilized power supply circuit 14 is supplied to the telephone. A dial signal from the telephone is supplied to the photocoupler 7 and the amplifier 8 when the telephone is in the form of a dial pulse signal. When the telephone is in the form of a dial tone (DTMF) signal, it is input to the CPU 6 via the capacitor 12 and the amplifier 13.

The CPU 6 refers to the flag data in the RAM 19, and when the number of the leading part in the dial signal from the telephone once stored in the RAM corresponds to a specific number (for example, a specific area code) where the flag is set, Based on the time information of the clock device 18 and the selection information in the RAM 19, the telephone line of the telecommunications carrier having the lowest charge at that time is determined, and an identification number for selecting the telephone line and a corresponding personal information number The dial number from the telephone is transmitted to the telephone line by the dialer 10 in the case of a tone signal and by the photo MOS relay 5 in the case of a dial pulse signal.

[Self-diagnosis] When a diagnosis start signal is output from the clock device 18 at predetermined intervals, the CPU 6 diagnoses each component of the line selection device for a failure based on a diagnosis program in the ROM 17.

[Flag Service] When a flag service request signal is generated at predetermined intervals from the clock device 18 in the line selection device 100i on the calling side, the CPU 6 sets the RA
The flag service telephone number in M19 is read, and the number is transmitted from dialer 10. As a result, the telephone 400 of the corresponding representative number is called, and one of the telephones 400i connected to the telephone 400 is ringed (that is, the CPU 210 in the corresponding DLP board 201i of the HC 200 by the ringer 220 in FIG. When a signal is input from the ringer 220, it is checked via the I / F 213 and the WS 202 whether there is any change in the corresponding data in the data storage device 600. If there is no change, the ringing is left as it is (not off-hook). Only when there is a change in the data, the telephone 400i is off-hook (ie, the relay 214 is switched to the line transformer 216) after ringing for a predetermined time, and the dialer 217 sends the call to the line selection device 100i on the calling side. The data is transmitted, and the line selection device 100i that has received the data.
In, the CPU 6 overwrites the data in the flag data area in the RAM 19.

[Failure Service] In each line selection device, a failure service start signal is output from the clock device 18 at predetermined intervals, and if a failure has been detected by the failure service processing of the CPU 6, the CPU 6 reads the ROM 1
The telephone number for trouble service in 7 is read out, and the number is transmitted from the dialer 10. Thus, the telephone 300i connected to the telephone 300 having one representative number is ringed.

In response, CPU2 of the corresponding DLP board 201i in HC200
The telephone 10 off-hooks the telephone 300i, inputs the fault information from the line selection device by the receiver 218, and sends out the fault service data in the data storage device 600 in accordance with the fault information in the predetermined order by the dialer 217. In response to this, on the line selection device side, CPU 6 sends DTMF sent from HC200.
The signal (data) is input via the capacitor 12 and the amplifier 13, temporarily stored in the RAM 19, overwritten in a corresponding area in the RAM 19, and the data change is completed.

Although the communication mode using the DTMF signal has been described above,
In addition to the DTMF signal, a digital signal using a modem can be used.

As described above, according to the present invention, by using a telephone having a unified telephone number (representative number) for each data processing, the data processing can be performed collectively and efficiently, and It is also very easy to change and manage the telephone numbers that have been set, and it is possible to provide a system that can very easily maintain and manage a large number of line selection devices.
