Abstract

PURPOSE:To attain an unmanned maintenance operation by inhibiting the incoming calls to a wire telephone circuit during the communication of a radio communication circuit. CONSTITUTION:An inhibition output 81 is applied to an incoming limiting circuit 2 from a squelch detecting circuit 8 to prevent the switching actions of a relay 11 while a radio equipment 200 is under a communication state and a squelch circuit is opened. However a tone transmitting circuit 9 is opened by another detection output given from a call detecting circuit 1 to supply the tone output of a tone ringer 10 with modulation through a transmission amplifier 5. Thus it is known that a phone patch is called to the remote side under communica tion. Then the communication is discontinued temporarily and the squelch circuit of the equipment 200 is closed. Thus the output 81 is erased and an incoming holding circuit 3 changes the relay 11 to the break side B. Then a phone patch call is possible. Here the present communication is important and the interrup tion of the phone patch is not desired. In such a case, it is possible to continue the communication as it is. Then the second call is carried out with an interval since it is known that a phone patch caller is busy from a fact that no circuit is connected.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic horn patch device suitable for unattended maintenance in a horn patch system in which communication is performed by directly connecting a wired telephone line and a wireless telephone line.

[Conventional technology and problems]

Hornpatch is a method of connecting a wired telephone line terminal directly to a wireless communication device to perform temporary wired-to-wireless communication. Because third parties other than amateurs are also allowed to make calls,
It has been widely used since ancient times. In Japan, the general use of horn patches has not been permitted due to regulations such as the Radio Law, but it seems that the trend will be relaxed in the future.

FIG. 2 shows the configuration of a conventional horn patch circuit.

The audio input/output circuit of the wireless device that performs a horn patch operation is connected to a wired telephone line through a hybrid circuit 4, a horn patch relay 11, and a horn patch switch 13.

The horn patch switch 13 connects the wired telephone line to the telephone 12.
and the horn patch circuit, and in the case of a manned horn patch, the horn patch switch 1 is always connected.
3 is placed on the telephone T side, and according to the horn patch application, flip the switch 13 to the horn patch P side to connect to the wireless line, and in the case of an unmanned operation horn patch, switch 13
If the telephone line 100 is placed on the side of the horn patch P, the telephone line 100 will be input to the ringing signal detection circuit 1 through the make contact M of the relay 11, and when a ringing signal is detected, the incoming call hold circuit 3 will operate and the relay 11 will break B. Switching to the side, the telephone line 100 is connected to the wireless communication device 200 through the hybrid circuit 4.
The horn patch operation is performed by connecting the

Therefore, if the radio operator is not present, the horn/4' switch 13 must be placed on the horn patch P side, otherwise horn patch communication will not be possible, and the switch 13 must be left on the horn patch P side. If the wireless communication device 200 is in use, interruptions from the telephone line 100 will occur indefinitely, disrupting wireless communication.

[Purpose of the invention]

The object of the present invention is to provide an automatic hornpatch device that connects a wired telephone line to a wireless communication device and enables unattended maintenance in a hornpatch operation that communicates through the wired-wireless line.

[Summary of the invention]

As disclosed in claim 1, this invention provides that when a call is made to connect from a wired telephone line to a wireless communication line, incoming calls on the wired telephone line are prohibited while the wireless communication line is communicating. It is an automatic horn patch device featuring
In the second clause, the prohibition of incoming calls on the wired telephone line is performed when there is no reception squelch control voltage of the wireless communication device, and in the third clause, the prohibition of incoming calls on the wired telephone line is based on the COR (Carrier) of the wireless repeater. 0per
at@dRe1ay) is performed when the input is ON, and in the 4th clause of this function, it is notified that the horn patch is ringing in response to a ringing signal of the wired telephone line which is prohibited from receiving calls on the wired telephone line. It specifies that the configuration is such that the ring tone is sent to the transmit modulator.

Details of its configuration and operation will be described in the section of the embodiments of the invention below.

[Embodiments of the invention]

FIG. 2 shows an example of the circuit configuration of the automatic horn/P-touch device of the present invention.

The wired telephone line 100 is connected to the telephone set 12 and also to the ringing signal detection circuit 1 through the make contact M of the horn patch relay 11. When a ringing signal is received from the telephone line 100, the ringing signal detection circuit 1 turns the relay 11 into a horn. /4' Outputs an operation command to the incoming call hold circuit 3 to switch to true operation. At that time, if the radio device 200 is in an idle line state, the relay 11 switches to the break contact B side, the telephone line 100 enters the hybrid circuit 4, and the received signal from the line passes through the transmitting amplifier 5 to the radio device 200. In addition to modulation input, VOX (Voice 0 operation)
In addition to the circuit, the radio device 200 is placed in the transmitting state, and when the signal from the telephone line 100 is cut off, the vOX circuit 7 transmits the radio device 20.
0 in the receiving state, the received signal from the detector is added to the hybrid circuit 4 through the receiving amplifier 6, and then added to the telephone line 100.
The horn patch operation is performed by sending the signal to However, if the wireless device 200 is in communication and the squelch circuit is open, the squelch detection circuit 8 applies a prohibition output 81 to the incoming call restriction circuit 2 to prevent the relay 11 from switching. However, another detection output from the ring detection circuit 1 opens the tone sending circuit 9, and modulates the tone output of the tone ringer 10 through the transmission amplifier 5. If you stop the call temporarily, the squelch of the radio 200 will close and the prohibition output will be 8.
1 disappears, the incoming call hold circuit 3 switches the relay 11 to the break B side, and a phone call can be made. At that time, if the current communication is important and you do not want the hornpatch to interrupt, you can just continue the communication as it is, because the horno or Tutsi caller will know that the line is busy because the line is not connected. , just call it again after a while. When the radio device 200 has a repeater configuration, the CO of the repeater
The R output may be used in place of a squelch operation, and in any case operates as an automatic horn four-titch device allowing for completely unattended maintenance.

〔Effect of the invention〕

According to this invention, in the horn patch operation, if the wireless device is in an idle state, the telephone line can be immediately communicated, and if the wireless device is in communication, the telephone line is not connected, so the person calling the horn Since there is no need to waste call charges and confusion caused by unexpected interruptions can also be avoided on the radio communication side, there is an effect that automatic home/no-yatch with completely unmanned maintenance can be performed.
