Abstract

The invention discloses a method and device for transferring an error code status, belonging to the field of communications. The method and the device are used for solving the problem that the realization of error code status transfer is complex. The method for transferring error code status provided by the invention comprises the following steps of: detecting a continuity check (CC) / connectivity verification (CV) message; if no CC / CV message is detected, reporting a signal fail (SF) alarm message to the network side; when the CC / CV message is detected, further detecting a forward defect indication (FDI) message or an alarm indication signal (AIS) message; and determining whether to report a signal degradation (SD) alarm message according to the detection result of the FDI message or the AIS message. The method and the device provided by the invention are applicable to the field of communications and are used for transferring the error code status.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for transmitting bit error status. Background technique [0002] In the existing communication technology, in order to ensure the accuracy of the packet switching process, the physical layer error detection is usually performed in the transmission network. In a packet-switching network, when the intermediate node detects the SD (Signal Degradation, signal degradation) error state or SF (Signal Fail, signal failure) error state at the physical layer, it usually modifies the FDI (Forward Defect Indication , forward defect indication) message or AIS (Alarm Indication Signal, alarm indication signal) message, or add a new message to carry SD or SF information, and send the message carrying SD or SF information to the downstream node point; when the end node receives the message, it processes the transmission network according to the situation of SD...
