A read-only integer giving the current result of the SDSL continuity test, refreshed at least once per second while the test runs and retained after the test stops. This value is how an admin gauges whether the copper pair has basic electrical continuity, a fundamental check before investigating more subtle line-quality issues. If cmSDSLTestContinuityTestResult indicates a discontinuity after the admin runs the test, they would suspect a physical break in the copper pair rather than a signal-quality problem.
