What is sonetAtmLCDs?

Counts the number of seconds during which this port experienced Loss of Cell Delineation, declared after 4ms out of cell-boundary sync and cleared after 4ms back in sync. An admin treats a nonzero count here as a sign the ATM layer briefly lost its ability to locate cell boundaries in the stream, usually alongside other physical-layer alarms.
