Description: This attribute represents the current measured round trip time on this CM's upstream channel in units of (6.25 microseconds/(64*256)). This attribute returns zero if the value is unknown.
What is docsIf31CmtsCmUsOfdmaChannelHighResolutionTimingOffset?
Reports the current measured round-trip time to this modem on its upstream OFDMA channel, in fine-grained units of 6.25 microseconds/(64*256) rather than the coarser units used by legacy DOCSIS timing objects; a value of zero means the timing is unknown. Admins can use this high-precision ranging offset to spot modems with unusually long or unstable cable/fiber runs that may need re-ranging or plant investigation.
