Clock Configuration
Clock Synchronization
In a synchronization network,
transport different synchronization levels transmits synchronization information. Each
synchronization network connection consists of one or more synchronization link
connection(s), Each synchronization link connection is provided by a synchronized
trail, SDH
Partial synchronization trail signal contain a communication channel that can transmit
the SSM, TM, or
used to select the input reference signal of the highest synchronization level from a set of
nominated synchronization references.
IEEE 1588
IEEE 1588, also known as the PTP, is a protocol for frequency and time of day distribution,
which is based on timestamp information exchange in a master-slave hierarchy, , whereby
the timing information is originated at a grandmaster clock that is usually traceable to a
PRC or UTC.
Similar to NTP, PTP nonetheless offers higher accuracy, with HW-based timestamping
support and fractional nanosecond precision.
