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

Abstract

This application relates to a method, device, device and medium for detecting and processing line faults in an analog telephone system. The method preliminarily connects the telephone set to the analog chip of the voice gateway through the A line and the B line, and pre-sets the voltage of the A line to 0V, and the voltage of the B line is 0V. The voltage is ‑48V, the voltage of A line and B line is ‑48V; regularly detect the line voltage value between AB; when the detected voltage value between AB lines and the output voltage becomes 0V, it is judged as a ground fault of B line; when detected When the output voltage of the voltage value between the A and B lines becomes 0V, it will automatically control the polarity reversal of the A line and the B line, control the voltage of the A line to ‑48V, and the B line voltage to 0V, and automatically repair the fault. The invention can automatically repair the line failure of the analog telephone system and ensure normal communication. The operation is simple and convenient, manpower is saved, the efficiency of fault repair is improved, and the cost of fault repair is saved; and the implementation 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...
