A kind of real-time monitoring method of onu equipment operating condition

Abstract

The invention provides a real-time monitoring method of an optical network unit (ONU) operating state. The method includes that step A, when finding that communication damage or communication outage happens to an ONU, the system sends an alarm and tells related ONU communication damage or communication outage, and step B, when the communication damage or the communication outage is restored, the system sends alarm restoration to tell related ONU communication damage or communication outage restoration. With the real-time monitoring method of the ONU operating state, the operating state of the ONU can be effectively monitored, and the fault position of the ONU can be found and located accurately and timely. The real-time monitoring method of the ONU operating state is convenient to use for timely isolating and restoring faults, ensures the reliable operation of the ONU to the maximum limit to relieve the working intensity of network managers, promotes the working efficiency and ensures the smooth communication of automatic business of distribution networks.

Description

technical field [0001] The invention relates to a real-time monitoring method for the operation status of ONU equipment, belonging to the technical field of communication network comprehensive management. Background technique [0002] The EPON (Ethernet Passive Optical Network) communication network adopts a point-to-multipoint topology, integrating the advantages of Ethernet technology and PON (Passive Optical Network) technology. The signal is transmitted between the Optical Line Terminal (OLT) and the Optical Network Unit ( OpticalNetworkUnits, ONU) transmission between. EPON (Ethernet Passive Optical Network) is a new type of optical fiber access network technology. It adopts point-to-multipoint structure and passive optical fiber transmission to provide various services on top of Ethernet. It adopts PON technology in the physical layer, uses Ethernet protocol in the link layer, and realizes the access of Ethernet by using the topological structure of PON. Therefore, i...

Problems solved by technology

If the channels from the two PON ports of the ONU leading to the OLTPON port are both in the fault state, the ONU device failure is a communication interruption; if only one channel is in the fault state, the system will automatically switch to the remaining normal channel. damage; if both channels are available, but due to unstable voltage, dirty PON port, etc., the performance such as data packet loss rate is degraded or potential danger, such failure is performance damage
