Speedup mode

3

Speedup mode is one of the values of the Line Rate parameter for setting the OTN line rate on WDM line boards and some optical wavelength transponders.
When WDM-side signals are OTU2e or OTU3e signals, or when client-side signals are 10GE LAN signals and Port Mapping is set to Bit Transparent Mapping (11.1 G) for the client-side port, set this parameter to Speedup Mode. In any other cases, set this parameter to Standard Mode.

Differences between the speedup mode and standard mode of the line board of OptiX OSN 8800
The rate in speedup mode is 11.1G and the service type is 10GE LAN. The service type is 10GE WAN in standard mode. When the speedup mode is used, the line boards need to be set to the speedup mode.

Method used to set the speedup mode for channels of the NS3 board
1. For ODU2 channels: Set them to speedup mode when the backplane side receives ODU2e services, and set them to standard mode when the backplane side receives ODU2 services. 2. For ODU3 channels: Set them to speedup mode when the backplane side receives ODU2e services, standard mode or speedup mode when the backplane side receives ODU2 services, and standard mode when the backplane side receives ODU3 services.

Compatible mode and standard mode
In V100R006C01 and later versions, some boards use a new board model. To distinguish the new board model from the existing board model, the new board model is called the standard mode and the original one is called the compatible mode. For boards in standard mode, the NMS displays the service mapping paths of trails or physical ports only, and all ODU-layer service mapping paths are displayed on physical ports. In standard mode, you do not need to consider logical ports of boards during cross-connect configuration. Compared with compatible mode, standard mode involves fewer mapping path layers, facilitating configuration and reducing maintenance costs. For example, among logical boards created on the NMS, 53TDX (STND) is in standard mode while 53TDX is in compatible mode, and 53ND2 is in standard mode while 53ND2 (COMP) is in compatible mode.

Difference between the subcard mode and board mode
The subboard mode refers to the current working mode of a subboard. The board mode refers to the current working mode of a board. Different types of boards and subboards support different types of working modes. Many commands are used to switch the subboard mode and board mode. These commands start with set service-mode. To set the subboard mode, you can run the set service-mode card or set service-mode slot card command in the system view. To set the board mode, you can run the set service-mode slot command in the system view.
