Description: The number of seconds in which Loss Of Frame (LOF) has occurred. A LOF is declared when an out-of-frame (OOF) condition persists for 3ms. The LOF is cleared when an in-frame condition persists for 3ms. While in-frame the framing bytes (A1, A2) in each frame are compared against the expected pattern. Out-of-frame is declared when four consecutive frames containing one or more framing pattern errors have been received.
What is sonetSectionLOFs?
Counts the number of seconds during which this port experienced Loss Of Frame, declared when an out-of-frame condition persists for 3ms and cleared after 3ms back in-frame. An admin watches this counter for framing instability, often indicating a clocking or cabling problem distinct from a full signal loss.
