Revision Standard - Active.
Protocols, procedures, and managed objects for the transport of timing over local area networks are defined in this standard. It includes the transport of synchronized time, the selection of the timing source (i.e., best timeTransmitter), and the indication of the occurrence and magnitude of timing impairments (i.e., phase and frequency discontinuities).
