Description: This attribute denotes the number of times the CM lost synchronization with the downstream channel. Discontinuities in the value of this counter can occur at re-initialization of the managed system, and at other times as indicated by the value of ifCounterDiscontinuityTime for the CM MAC Domain interface.

What is docsIf3CmStatusLostSyncs?

Counts how many times the CM lost synchronization with its downstream channel. A rising count usually means downstream RF trouble (weak signal, noise) causing the modem to repeatedly drop lock.
