Maximum access rate of the TN52TOM board when the board works in tributary-line non-cascading mode and the dual-feeding and selective receiving function is enabled on the WDM side
In this scenario, three encapsulation paths are available for the TN52TOM board: Any->ODU0->ODU1->OTU1 OTU1->ODU1->Any->ODU0->ODU1->OTU1 OTU1/Any->ODU1->OTU1 The maximum access rates are 5 Gbit/s for all the three encapsulation paths.

Cause why the LTX board can be selected during cross-connection configuration
The mapping inside the LTX board is fixed, and therefore no cross-connection needs to be configured.
