Physical-layer clock synchronization

11

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.

Can NTP be set for the MCU?
The NTP server cannot be set for the ViewPoint 8000 series MCU. The NTP server can be set for the VP9000 series MCU. Log in to the VP9000 series MCU web interface, choose Setting > System > Time, select NTP, and configure the IP address for the NTP server.

Clock synchronization modes supported by OptiX OSN 8800
When an OptiX OSN 8800 device is interconnected with an MSTP or PTN device, the IEEE 1588v2, synchronous Ethernet, 2 MHz and 2 Mbit/s external clock sources are supported to implement end-to-end clock transmission. When an OptiX OSN 8800 device uses IEEE 1588v2 to implement phase synchronization, the supported NE working modes are OC, TC, BC, TC+BC, and TC+OC.
