Abstract:
A method, system and device for monitoring error code of CPRI link are disclosed. The method comprises: a CPRI link data transmitting end forming data to be transmitted into frames, outputting data, and calculating to obtain FCS of each frame; the CPRI link data transmitting end adds FCS of a former frame into FCS field of a current frame when forming frame; a CPRI link data receiving end splitting frame of received frame data to obtain FCS of the former frame carried in the current frame, calculating received frame data to obtain FCS of the current frame, caching FCS of the current frame, comparing FCS of the former frame which is carried in the current frame with cached FCS of the former frame, and judging CPRI link has error codes if the comparison result is inconsistent. Error code condition of CPRI link can be monitored without influencing normal service operation.
