Description: The counter associated with the number of Errored Seconds encountered by a E1/T1 interface in the history bin.

What is e1t1HistoryLineESs?

This PerfCounter64 counts Errored Seconds encountered by an E1/T1 interface's line layer in the history bin. An admin uses line ES history to gauge how noisy a T1/E1 span has been over each collection period, as a first-line indicator before checking the more severe SES or LOS counters. If e1t1HistoryLineESs is consistently higher during evening bins than daytime bins on a given T1, the admin might suspect a time-correlated environmental factor such as temperature-driven cable expansion.
