If the line connection is reversed due to a wiring mistake, etc., it should be connected to the positive side.
If the L 1 terminal is connected to the negative side,
There is a drawback that the situation is equivalent to the fact that a calling signal is received even though there is no calling signal from the calling party, and automatic transmission of a dialing signal cannot be performed.

ヤル信号を送出できるように構成されている。 FIG. 1 is a circuit diagram showing an embodiment of the present invention. In the same figure, 101 and 102 are telephone lines.
This is a line switching contact that connects a device such as a modem or facsimile device to the L 1 and L 2 terminals, and when a calling signal is detected, it switches to the side opposite to the side shown in the diagram, and the signal from the calling side is sent to the equipment side via the DC prevention capacitor 111. On the other hand, the line switching contacts 101 and 102 are switched to the side shown in the figure when waiting for an incoming call or making a call, and the L1 terminal and
It is configured such that a dial signal can be sent from the dial signal sending circuit 103 to the L2 terminal.

A polarity reversal detection circuit 108 for detecting that the polarity of the response signal from the called side has been reversed is connected thereto. These calling signal detection circuits 105,
Call collision detection circuit 106, polarity reversal detection circuit 1
The detection output signals of 08 are input to the control circuit 109, and the line status is determined based on these detection output signals. If the line is idle, the dial signal sending circuit 103 is permitted to automatically send out a dial signal. The control signal is configured to be applied to the control signal. Note that 110 is a current limiting resistor.

て、回線に自動的にダイヤル信号が送出される。 First, the outgoing/incoming call collision detection circuit 106 monitors whether or not a outgoing/incoming call conflict has occurred at all times or only when a command is given from the control circuit 109. If not, the control circuit 109 outputs a detection output signal indicating this fact.
give to Then, upon receiving this collision-free detection output signal, the control circuit proceeds to the automatic dialing operation shown in step 121 after making the determination in step 120 in FIG. do. This automatically sends a dial signal to the line.

（ステツプ１２５）。 However, when a detection output signal indicating a collision state between incoming and outgoing calls is outputted from the detection circuit 106, the control circuit 109 determines whether or not a ringing signal detection output signal is outputted from the ringing signal detection circuit 105. 122), if the calling signal detection output signal is output, it is determined that the calling signal has truly arrived, and the process moves to the receiving operation (step 12).
3). However, if the ringing signal detection output signal is not output, that is, if the ringing signal has not arrived, it means that a call collision has occurred even though there is no ringing signal, and the line is reversely connected. (Step 12)
4) After that, the process moves to an automatic dialing operation (step 125).

自動ダイヤル送出動作に移行する。 That is, even if the detection circuit 106 detects a call conflict, if a ringing signal is not detected, the control circuit 109 determines that a call conflict is occurring due to reverse connection of the line, and performs normal automatic operation. Shifts to dial sending operation. In other words, although the connection is reversed, it is determined that the dial is in the "vacant state", the detection output of the detection circuit 106 is ignored, and normal automatic dialing operation is performed.

ヤル送出動作を確実に行うことができる。 After this, the control circuit 109 detects the line polarity inversion signal which is the called side response signal (step 126).
However, at this time, the polarity inversion state is defined as a state inverted from the normal state based on the determination result indicating that the connection of the telephone line is in the reverse state, that is, the L1 side (-) and the L2 side (+). Thereby, even if the connection state of the telephone line is reversed from the normal state, the automatic dialing operation can be performed reliably.

The period can be shortened.

As explained above, according to the present invention, there is provided a means for determining whether the line is in a normal idle state or an idle state due to reverse connection of the line, based on the detection outputs of both the call collision detection circuit and the ringing signal detection circuit. This feature makes it possible to reliably send dial signals automatically regardless of the connection status of the line, eliminates the need to check the polarity using a tester, etc. when connecting a telephone line, and also eliminates the need for line replacement work on the exchange side. This has the effect of providing a stable automatic dialing function even if the connection status is reversed.
