This will enable/disable the error threshold monitoring. Error threshold monitoring looks for errors on the physical line. When there have been efmCuPmeErrorThreshMonInterval number of consecutive seconds with errors the line will first be taken down with a retrain in hopes of bettering the SNR to rectify the error situation. If, when the line comes up, we do not achieve efmCuPmeErrorThreshMonClrInterval number of consective error-free seconds before hitting another efmCuPmeErrorThreshMonInterval number of consecutive seconds with errors, the line will cease to be used for carrying traffic. The physical line will remain active so error monitoring can continue but data will no longer traverse until efmCuPmeErrorThreshMonClrInterval number of consecutive error-free seconds is achieved, at which time the line will resume carrying traffic.
