Analog telephone system line fault detection processing method and device, equipment and medium

Abstract

The invention relates to an analog telephone system line fault detection processing method and device, equipment and a medium, and the method comprises the steps: enabling a telephone to be connectedwith an analog chip of a voice gateway through an A line and a B line in advance, and presetting the A line voltage to be 0V, the B line voltage to be-48V, and the A line voltage and the B line voltage to be-48V; detecting a line voltage value between A and B at regular time; when it is detected that the voltage value output voltage between the A line and the B line becomes 0 V, judging that a B line ground fault occurs; and when it is detected that the voltage value output voltage between the A line and the B line becomes 0V, automatically controlling the A line and the B line to perform polarity inversion, controlling the voltage of the A line to be-48V and the voltage of the B line to be 0V, and automatically repairing a fault. According to the method, the line fault of the analog telephone system can be automatically repaired, and the normal call is ensured. The operation is simple and convenient, the manpower and material resources are saved, the fault repairing efficiency is improved, and the fault repairing cost is saved; and the realization is easy and the reliability is high.

Description

technical field [0001] The present application relates to the technical field of voice communication, in particular to a method and device for detecting and processing an analog telephone system line fault, computer equipment, and a readable storage medium. Background technique [0002] POTS (PlainOldTelephoneService): analog telephone service, such as figure 1 As shown, it is connected to the above voice gateway through a twisted pair, this line is called pots line, there are 2 lines, one is called A line (ground line, output 0v voltage), one is called B line (output -48v voltage). [0003] In the existing technology, this kind of telephone line is often moved from the computer room to the user's home, which is often far away. It is exposed to the wind and the sun outdoors. As time goes by, if the rubber ages, there may be line quality problems that cause the phone to fail. For example, the B line is grounded (for example: the B line is exposed and connected to the ground...
