7.126 S1 Byte Synchronization Quality Information

Description
The S1 Byte Synchronization Quality Information parameter indicates the synchronization
quality information in the S1 byte that is output by the current traced synchronous source. The
S1 byte defined by the ITUT is used to transmit the quality information about the clock sources.
It indicates the quality information of 16 types of synchronous sources with bits 5-8 of the S1
byte in the section overhead. With this quality information and certain switching protocols, the
automatic protection switching of the synchronization clock can be realized in the synchronous
network.
Impact on the System
The system running is not affected.
