Service based fault localization method and apparatus

Abstract

The utility model relates to a operation-based fault location method, which is used for WDM / DWDM system. The utility model comprises step 1: WDM / DWDM-based operation is established for the network administration; step 2: checking whether the alarm on the SNMS-related single board disrupts the operation test; if No, conduct step 3; if yes, stop test; step 3: the test signal produced by the single board at the operation start position can be tested by the single board at the operation end position. When the test result is outputted, the test stops. The utility model can conduct the operation examination and fault location without the gage unit, so as to reduce the restriction from the external conditions; the testing process can be conduced automatically. Thus, manual operation can be saved as far as possible; in addition, a plurality of wavelength tests can be carried out at the same, so as to save the time.

Description

technical field [0001] The invention relates to wavelength division multiplexing / dense wavelength division multiplexing (WDM / DWDM) system transmission equipment in the field of optical communication, in particular to a service-based fault location method and device. Background technique [0002] At present, when the DWDM system is in the factory inspection and the equipment commissioning test cutover of the bureau, for each wavelength, it is necessary to hang a separate instrument for 24 / 72 hours of bit error testing. During the factory inspection, it is also possible to cascade the client-side output and client-side input of different boards with optical fiber jumpers, so that one instrument can complete the test of the entire system. However, at the beginning of the deployment, it is often necessary to have engineers at the two sites of the test. The engineers at one site will jump the optical fiber, and the other site will hang up the instrument for testing. Therefore, t...

Problems solved by technology

Therefore, the verification of the entire system often takes a lot of time

[0003] In addition, in the system running on the network, if the service of a certain wavelength fails, sometimes the alarm information provided by the network management system (referred to as the network management) cannot accurately help locate the fault, and often requires an instrument to help locate the fault.

[0004] In the case of not connecting to the instrument, it will often increase the difficulty of fault location and solution
