Application scenario of the LCK insertion function

The LCK insertion function is provided for users to lock channels. You can determine whether to enable the LCK insertion function as required.
When the LCK insertion function is enabled, client-side signal transmission is stopped and LCK signals are inserted to the WDM side.
If LCK insertion is enabled for the upstream board, the ODUk_PM_LCK alarm will occur on the downstream board. When TCMn monitoring is enabled for the downstream board, the ODUk_TCMn_LCK alarm will also be reported.
