This object reports the quality level being advertised or embedded in the timing signal sent out of a specific T4 external output, telling downstream equipment how trustworthy this device claims its distributed clock to be. It matters because if the device itself is currently in holdover or degraded, this output quality level should reflect that degradation so downstream equipment can make informed decisions rather than blindly trusting a stale good-quality claim. An admin seeing this report a Do-Not-Use quality level would want downstream equipment to be actively avoiding this output as a timing source, and should confirm downstream gear is respecting that.
