1. Introduction

   Frequency synchronization based on physical layer clock is
   generally implemented in network elements and deployed widely in
   various networks. To achieve frequency synchronization, the
   physical clock is delivered from a PRTC to an end device across the
   network over a series of physical links such as PDH, SDH/SONET, OTN
   or IEEE 802.3.

   This document defines a YANG data model for the configuration of
   frequency synchronization over a single physical link (simplified
   as Sync PHY) such as Sync Ethernet (SyncE) or Synchronous Optical
   Transport Network (SyncO). The data model is constructed based on
   the management attributes as specified in [ITU781] and reference
   source selection architecture as described in [ITU8264]. The data
   model is targeted at supporting generic Sync PHY for network
   elements and industrial internet devices, the details on these
   physical layer synchronization can refer to those ITU-T
   recommendations such as [ITU783], [ITU8021], [ITU798] and are out
   of scope of this document.

   The YANG module in this document conforms to the Network Management
   Datastore Architecture (NMDA) [RFC8342].
