OSN 8800 boards that support physical-layer clock signals
All boards of the OSN 8800 support the following operations on physical-layer clock signals: external frequency source access and internal frequency source transmission.

Method used to configure licenses of OptiX OSN 8800
OptiX OSN 8800 licenses, such as universal line board license, TP-Assist license, and the license for OptiX OSN 8800 T32 universal subrack, need to be configured on the U2000. The procedure is as follows: 1. In the main topology, choose Configuration > NE Batch Configuration > NE License Authorization. The Choose License window is displayed. 2. In the Choose License window, select the license to be loaded and click OK. The NE License Authorization window is displayed. 3. On the left side of the NE License Authorization window, select the desired NE from the navigation tree. 4. On the right side of the window, set the license.

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.

Physical-layer clock synchronization
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.
