Clock synchronization

Dear Bora,

Physical-layer clock synchronization is a method of recovering clock frequencies from physical signals. The purpose is to achieve frequency synchronization between upstream and downstream devices so that services are transmitted properly. When an OTN network transmits clock synchronization signals, these signals can be obtained by SDH and PTN networks. No separate BITS clock source needs to be provided for the SDH or PTN network. In this way, network-wide clock synchronization is achieved.

Good day!
