Abstract

This application relates to a FXS port line protection method and device, computer equipment, and media. The method includes: starting a task to monitor the AC, DC short circuit and grounding abnormal events provided by the SLIC. When abnormal events are monitored, it will enter the protection state and enter The protection state will set the line to disconnect (disconnect) state and at the same time set the line state to standby (waiting, standby) every 100ms to let the SLIC chip detect whether the abnormality is resolved or not. When the software task finds an abnormal release event, the protection state is over, and the port is restored to the state of normal use. The invention can realize the detection of abnormal lines, and report the abnormality to the alarm system in time, and notify the manual to check the abnormality, and after the abnormality is resolved, the FXS line can be automatically restored, which provides convenience for use.

Description

technical field [0001] The present application relates to the field of port line protection, in particular to a FXS port line protection method and device, computer equipment, and a readable storage medium. Background technique [0002] During the wiring or long-term maintenance of telephone lines by telecom operators, it is inevitable that the two telephone lines will be short-circuited or the telephone line will be grounded. may burn out due to heat. (FXS English name is Foreign Exchange Station, external exchange station. It is a voice interface, which is a line-side connection between a digital telephone switching system and a POTS telephone. It simulates the extension interface of PABX (or the user interface of the central office) , which can realize the connection between an ordinary telephone set and a multiplexer. Simply put, it is an interface directly connected to an ordinary analog telephone set and a fax machine. It is an interface connected to a user-side telep...
