Description
technical field [0001] The present invention relates to the technology of optical transmission equipment, in particular, relates to a 2M circuit system for monitoring optical transmission equipment and a testing method thereof. Background technique [0002] The communication SDH optical transmission equipment mainly monitors the alarm through network management monitoring. When the staff temporarily leaves the network management interface, it is impossible to find out in time that the SDH optical transmission equipment is powered off, the cross-connect board, and the main control board are faulty. Or the major failure of the link interruption between the equipment caused by the interruption of the optical cable, which leads to the interruption of a large number of services carried on it and cannot be recovered in time; it is also impossible to detect the instantaneous interruption of the circuit caused by the error code caused by the fault of the equipment card and optical ca...
