The Octet Operator Survival Guide — Field Manual 6 · PTP & Timing

PTP and timing

You stop being the tech who watches a green dashboard while the show falls apart and has no idea why. You stop checking the thing that is already right. You learn how time actually moves across an IP facility: the four messages that measure it, the clock hierarchy that scales it, the profile that pins it for media, and the four ways it breaks. You become the operator who looks at a stuttering picture and a locked PTP display and knows those two facts aren't in conflict, then names the failure class before the producer finishes the sentence.
