This is a running tally of how often the structured CBR card lost the structure pointer since the last reset -- the counter form of the state reported by lportLossOfStructurePointer. An admin uses this counter to distinguish a one-time blip from a chronically unstable structured-CBR circuit: a count stuck at 1 suggests a transient event, while one climbing by dozens per day suggests a persistent framing problem needing card or cabling attention. For example, a jump of 30 in one day on a fractional-T1 CBR circuit would justify checking the DS0 channel mapping configuration on that lport.
