METHOD AND DEVICE FOR PROCESSING LINE DETECTION

摘要

Embodiments of the present invention provide a line detection processing method and a device. The line detection processing method in the present invention includes: detecting, by using a detection circuit, whether reverse power supply on a twisted pair line is discontinued; if the reverse power supply on the twisted pair line is discontinued, triggering a status switch to switch from a normal power supply state to a backup power supply state, so as to simultaneously trigger a line detection module and an energy storage capacitor; and performing detection on the twisted pair line between the line detection module and a user equipment by using the line detection module, and supplying power to the line detection module by using the energy storage capacitor. By using the method, a fiber to the distribution point device can perform detection on a twisted pair line if reverse power supply is discontinued.
