Description:
TN53NQ2/TN54NQ2/TN57NQ2 need to set the "Single Board Mode", and the "Single Board Mode" of this application scenario is: "Normal Line Mode".
TN51NQ2/TN52NQ2/TN53NQ2/TN54NQ2/TN57NQ2 Single Board Application Scenario 2: Realize the inter-conversion between 4-channel ODU2/ODU2e signals and 4-channel OTU2/OTU2e signals.

Description:
TN53NQ2/TN54NQ2/TN57NQ2 need to set the "Single Board Mode", and the "Single Board Mode" of this application scenario is: "Normal Line Mode".
TN52NQ2/TN53NQ2/TN54NQ2/TN57NQ2 Single Board Application Scenario 3: Realize the interconversion between 32-channel ODU0 signals and 4-channel OTU2 signals (only supported by OptiX OSN 8800)
Figure 3NQ2 single board in WDM system application scenario 3
Description:
TN53NQ2/TN54NQ2/TN57NQ2 need to set the "Single Board Mode", and the "Single Board Mode" of this application scenario is: "Normal Line Mode".
For TN53NQ2/TN57NQ2:
In "Standard Mode", when the ODU time slot method is configured as "Auto Continuous", it supports ODU0->ODU1->ODU2.
In "Standard Mode", ODU0->ODU1->ODU2 are supported when "Auto Random" is configured for ODU time slot method.
In "Compatible Mode", the configuration of ODU time slot mode is not supported, only ODU0->ODU1->ODU2 is supported.
TN53NQ2/TN57NQ2 single board application scenario 4: Realize the inter-conversion between 8-channel ODUflex signals and 4-channel OTU2 signals (only supported by OptiX OSN 8800)
Figure 4NQ2 single board in WDM system application scenario 4
Description:
The total bandwidth of the two ODUflexes corresponding to each OTU2 cannot exceed 10 Gbit/s.
TN53NQ2/TN57NQ2 need to set the "Single Board Mode", and the "Single Board Mode" of this application scenario is: "Normal Line Mode".
For TN53NQ2/TN57NQ2, ODUflex is only supported in standard mode.
TN53NQ2/TN54NQ2/TN57NQ2 Single Board Application Scenario 5: Relaying OTU2/OTU2e signals
Figure 5NQ2 single board application scenario 5 in WDM system
Description:
TN53NQ2/TN54NQ2/TN57NQ2 need to set the "Single Board Mode", which can be set to "Electrical Relay Mode" or "Optical Relay Mode". For optical-layer ASON and electrical-layer ASON applications, setting "optical relay mode" and "electrical relay mode" has no effect on the system; for non-ASON applications, only "optical relay mode" can be set for end-to-end operation. For non-ASON applications, only "Optical Relay Mode" can be set for end-to-end management.
The sending and receiving optical ports of the same relay signal must be configured as follows, otherwise the ESC communication will not work.
IN1->OUT1 and IN2->OUT2
IN3->OUT3 and IN4->OUT4
The pair of IN/OUT ports in this scenario supports different input wavelengths and output wavelengths.
Application Scenario 6: Hybrid Transmission Scenario
Figure 6 NQ2 Single Board in WDM System Application Scenario 6
Description:
The same IN/OUT port supports mixed transmission of ODU0, ODU1, and ODUflex with a maximum bandwidth of 10Gbit/s.
The same single board can realize the mixed transmission of ODU0, ODU1, ODU2/ODU2e, and ODUflex level signals.
Only TN52NQ2/TN53NQ2/TN54NQ2/TN57NQ2 support ODU0.
Only TN53NQ2/TN57NQ2 supports ODUflex in standard mode.
The "ODU time slot configuration mode" parameter settings of the line boards at the two sites of the up and down services must be the same. When the TN53NQ2/TN57NQ2 boards are interfaced with the boards that do not support the setting of the "ODU time slot configuration mode" parameter, the "ODU time slot configuration mode" parameter is set to "ODU0". When TN53NQ2/TN57NQ2 boards are connected to a single board that does not support the setting of "ODU time slot configuration mode" parameter, the "ODU time slot configuration mode" needs to be set to "auto continuous". For example, if TN53NQ2/TN57NQ2 is interfaced with TN52NQ2, since TN52NQ2 does not support the setting of "ODU Time Slot Configuration Mode" parameter, the "ODU Time Slot Configuration Mode" parameter of TN53NQ2/TN57NQ2 must be set to "Auto Continuous". The "ODU time slot configuration mode" parameter of TN53NQ2/TN57NQ2 must be set to "Auto Continuous".
Only 52ND2T04, TN53ND2, TN57ND2, TN53NQ2, TN57NQ2, TN52NS2T04, TN52NS2T05, TN52NS2T06, TN52NS201M01, TN52NS201M02, TN53NS2, TN54HUNQ2 support the setting of the "ODU time slot configuration mode" parameter.
