csOrionOc3PosStatsEnd is a read-only Integer32 object whose own description states plainly that its value is undefined; it exists purely as a structural marker signaling the end of the OC3 POS statistics group in this MIB. An admin or a MIB browser walking through the OC3 POS statistics objects in order uses this object as a sentinel to know they've reached the end of that group, not as a piece of real performance data to monitor or alarm on. For example, a script doing a GETNEXT walk of the csOc3Pos* objects would treat hitting csOrionOc3PosStatsEnd as the signal to stop collecting POS statistics for this interface, rather than trying to interpret its returned value as meaningful.
