SYNCOOS (Timing reference failed (Not Protected or
Protection not Available)) / SYNCOOS (Timing reference
failed--system going into holdover)
One of two causes for SYNCOOS:
• The OT port has detected SYNCOOS at the LINEREF layer. A LINEREF detects
SYNCOOS when the timing reference failed, (not Protected or Protection not

SYNCOOS when all available timing references have failed and the system is going
into holdover.
