What is foreSonetPathTotalPLMs?

Counts the number of seconds in which a Path Payload Label Mismatch (PLM) defect occurred, detected when the C2 signal label byte holds a value other than the expected set (0x00, 0x01, 0x13, 0xFC, or 0xFF). It flags a mismatch between the payload type the far end is sending and what this port expects.
