Method used to shut down a board laser
Select the desired board in the NE Explorer. Choose Configuration > WDM Interface from the navigation tree. Select By Board/Port(Channel) and choose Channel from the drop-down list. On the Basic Attributes tab, double-click Laser Status of the desired optical port, and then select Enable or Disable from the drop-down list to change the laser status.

Whether the THA and TOA boards support tributary-line mode
No. The THA and TOA boards do not support tributary-line mode. Only the TOM board supports tributary-line mode.
