What is e1t1HistoryLineLOSSs?

This PerfCounter64 counts Line Loss Of Signal Seconds encountered by an E1/T1 interface in the history bin. An admin checks LOS history specifically to identify hard outages (cable cuts, dead transmitters) rather than marginal error conditions, since LOS means no signal was present at all. If e1t1HistoryLineLOSSs shows a spike exactly during a scheduled fiber splicing job in the area, the admin can attribute that outage to the known maintenance rather than opening a new fault investigation.
