Latency measurement supported by some boards on OTN equipment
To support the latency measurement function, the specified NMS license must be available. In addition, not all boards support the online latency measurement function. The following lists R007C02SPC300 boards that support online latency monitoring: 1. 2.5G tributary boards: TN54TOA, TN54THA, and TN54TOG 2. 10G tributary boards: TN57TOA, TN53TQX, TN53TDX, TN55TQX, TN57TQX, TN55TOX, and TN54TTX 3. 10G OTU boards: TN11LOA and TN14LSX 4. 100G tributary boards: TN54TSC

ODUk SNCP protection switching conditions
ODUk SNCP is classified into SNC/I, SNC/N, and SNC/S. The difference between the three protection schemes lies in that they have different monitoring capabilities and therefore have different trigger conditions.

Whether service connections can be implemented between TOA and TOG boards
Yes. Service connections can be implemented between TOA and TOG boards.

Whether service provisioning is affected if a synchronous device is added to an OTN ring of an asynchronous system
A synchronous system and an asynchronous system can be interconnected with each other.
