Abstract

PURPOSE:To attain the setting of various parameters from a telephone system terminal, to make the device small, to simplify the device and to quickly set and revise a parameter at an installed location of the device. CONSTITUTION:When a telephone system terminal 21 is hooked off and it is detected by a detection section 1, a dial tone generating section 3 is started and a call tone is sent to the telephone system terminal 21. Then a mode changeover switch 17 is checked to discriminate which of the operation and the setting modes is selected. In the case of the operation mode the operation of communication is implemented. Moreover, in the case of the setting mode, a DTMF signal detection section 4 is started and a DTMF signal from the telephone system terminal 21 is awaited. When no DTMF signal is received within a prescribed time, a call progress signal generating section 8 is started, a howler tone is sent and the on-hook is awaited.

Note that the memory 10 stores a parameter registration table, which will be described later, and a register for temporarily storing numbers received from the telephone terminal 21.

[0013] This auto-dialing device also includes a calling signal detection section 11 for detecting a calling signal from the network 22 side, a loop forming circuit 12 for forming a DC loop,
a polarity reversal detection unit 13 that detects polarity reversal on the side of the network 22;
After the DC loop is formed, a tone detection section 14 that detects a tone sent from the network 22 side, a call progress signal detection section 15 that detects a status display signal from the network 22 side, and the type of central office line are set. a transmission signal setting switch 16 for switching, a mode setting switch 17 for switching operation and setting modes, and line switching circuits 18a and 1 for switching lines.

It has an F section 20.

A destination telephone terminal (not shown) is also connected via the public telephone network 22.

FIG. 2 is a flowchart showing the operation when setting the parameters of such an auto-dialing device from the telephone terminal 21, and FIG. 3 is a schematic diagram showing the sequence of parameter setting.

First, when the telephone terminal 21 is hooked off and the detecting section 1 detects this (S1), the dial tone generating section 3 is activated and a dial tone is sent to the telephone terminal 21 (S2). .

Next, referring to the mode changeover switch 17 (
S3), it is determined whether the mode is operation or setting (S4). Note that the mode changeover switch 17 is manually switched by, for example, an operator of the telephone terminal 21.

If it is in the operation mode, normal operation is performed (S21).

Further, in the setting mode, the DTMF signal detection section 4 is activated and enters a state of waiting for a DTMF signal from the telephone terminal 21 (S5). Then, within a certain period of time, DTMF
If the signal is not received (S5a), the call progress signal generator 8 is activated, a howler sound is sent to the telephone terminal 21 (S6), and the ON hook waiting state is entered (S7).

[0020] Also, within a certain period of time, D
When the TMF signal is received (S5a), it is decoded by the DTMF signal detection section 4 and stored in a register in the memory 10 (S8).

Then, referring to the parameter storage area in the memory 10, it is determined whether a table matching the decoded number exists (S8). In this example, the table numbers are "#*1", "#*2", "#*3".
” are available.

If there is no table matching the decoded number (S8a to S8c), the DTMF signal generator 5 generates an error tone and the telephone terminal 2
1 (S9) and enters the ON hook wait state (S1
0).

Further, if the existence of a table of decoded numbers is confirmed (S8a to S8c), the DTMF signal generator 5 generates a response signal corresponding to the table number and sends it to the telephone terminal 21 (S11). ~S13).

Next, after sending this response signal, the next DTM
The system enters a state of waiting for reception of the F signal (S14). Then, if no DTMF signal is received within a certain period of time (S14a),
Sends a howler sound and enters the ON hook waiting state (S6,
S7).

[0025] Furthermore, if the next DTMF signal is received within a certain period of time (S14a), the ON hook waiting state is established (
S15), if an ON hook is detected within a certain period of time (
S16), conditions such as the number of digits are confirmed (S17). Then, if the conditions are correct, the parameter values are changed (S1
8).

On the other hand, if the ON hook cannot be detected within a certain period of time (S16), a howler sound is sent out and the ON hook wait state occurs (S6, S7). At this time, the parameter values on the table are not changed (S19). Further, even if the received parameter violates the conditions, the parameter value on the table is not changed (S20).

Therefore, the parameter values on the table are changed only when an ON hook is detected within a certain period of time and the conditions of the received parameters are correct.

In this way, the DTMF from the telephone terminal
The signal allows parameter values to be set (changed).

[0029]

[Effects of the Invention] As explained above, the ability to set various parameters from a telephone terminal has the following effects. (1) Since functions such as a numeric keypad and a disk drive are not required in the main body of the device, the device can be made smaller and simpler. (2) No special equipment is required on the center side for parameter setting. (3) No standard terminal or dedicated terminal is required for parameter setting.

[0030] Therefore, it is possible to quickly set and change parameter values at the installation location of the device.
