What is slSonetApsChanSignalFailures?

A read-only counter of Signal Failure conditions on this line, triggered by loss of signal, loss of frame, AIS-L, or a bit error rate exceeding 10^-3. Rising counts here indicate more serious line problems than signal degrades, and likely correlate with actual APS switchovers.
