Module: Fore-SONET-MIB
OID (symbolic): Fore-SONET-MIB::sonetSectionLOSs

Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of seconds in which Loss Of Signal (LOS) has occurred. A LOS is declared when 20 +/- 3us of all zeros patterns is detected. LOS is cleared when two valid framing words are detected and during the intervening time no LOS condition is detected.
What is sonetSectionLOSs?
Counts the number of seconds during which this port experienced Loss Of Signal, declared when ~20us of all-zero pattern is detected and cleared once two valid framing words are seen. An admin treats a nonzero count here as evidence of a physical link outage on this port rather than a protocol-level issue.
