SSM and PTP Interaction

PTP carries clock quality in its datasets in the structure defined by the IEEE 1588 specification. The Ordinary Clock (OC) master carries the Grand Master (GM) clock quality in its default dataset which is sent to the downstream OC slaves and Boundary Clocks (BC). The OC slaves and BCs keep the GM clock quality in their parent datasets.
