Embodiment Construction

[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0025] Fig. 1 is a flow chart showing a bit error switching method according to the present invention. Referring to Fig. 1, the error switching method according to the present invention comprises the following steps: step S102, wait for the arrival of the first time, and carry out error statistics when the first time arrives; step S104, judge whether to arrive at the second time, if not arrive At the second time, return to step S102, otherwise, record the current bit error statistical data; step S106, clear the historical bit error data, and notify that the bit error statistical data has been recorded; and step S108, perform bit error processing.

[0026] Step S108 includes the following processing: step S108-2, judging whether the error statistics data has been recorded; step S108-4, if the error statistics data has been recorded, t...

Abstract

The invention discloses a method and a device of switching error codes. The method includes the steps as follows: Step S102, wait for the arrival of a first time and perform error statistics when the first time arrives; Step S104, judge whether the second time is reached or not, and if not, turn back to Step S102, otherwise record the current error statistics data; Step S106, remove the history error data and notice that the error statistics data have been recorded; and Step S108, process the error. The invention improves the error-switching reliability and ensures that SDH equipment provides reliable services.

Description

technical field [0001] The invention relates to a method and a device for improving the stability of bit error switching, in particular to a method and a device for the stability of protection switching caused by bit errors in an optical synchronous digital transmission system (SDH). Background technique [0002] At present, SDH equipment generally realizes the bit error detection function of B1, B2, B3, and V5 bytes according to the ITU-T standard, and performs more complicated processing on the result of bit error detection, such processing includes counting errors based on statistics. Corresponding service switching. There are two existing bit error detection and processing methods, which are described as follows: [0003] One is processed by a process, and after the error code detection and statistics are performed, the error code processing is performed in this process, and then the statistical data is cleared. The problem with this method is: before the bit error pro...
