Method for determining whether the wavelength of the TN53ND2 board is tunable
Query board manufacturer information and check the description of the module. "Tunable" indicates that the wavelength of the optical module is tunable.

Method used to determine whether a board supports tunable wavelengths
On the NMS, query the manufacturer information of the desired board. If "Tunable" is included in the information, the board supports tunable wavelengths.

Methods for determining whether the standby board and the board in use are of the same type from board barcodes
If the first six digits in the barcode of the boards are the same, and the first six digits in the 03+ barcode queried on PDM system are the same, you can replace the board in use with a spare board. You can also check the board type information on the front panel of the board. If the types are the same, you can replace the standby board with the board in use.

Whether the TOM board has wavelength or frequency limitations
When functioning as a pure tributary board, the TOM board does not have any frequency limitation and it supports all broad-spectrum optical signals. When the TOM board functions as an OTU board, its WDM-side ports have frequency limitations.

Method used to determine whether the TN52TOM board properly transmits internal services
The Ethernet maintenance function provided by the TOM board can be used to determine whether the TOM board properly sends internal services based on the sent and received test frames.
