This section describes the board working mode and port working mode. A specific service signal flow of a board is available when the board working mode and port working mode are set to specific values.
Board Working mode
The U2000 Web LCT supports a variety of board working modes.
The 12LQMS board supports NS1 and LQM.
- In NS1, the 12LQMS board functions as a line board that performs the mutual conversion between the ODUk electrical signals and the optical signals at a WDM system-compliant standard wavelength.
- In LQM, the 12LQMS board functions as a tributary-line board that performs the mutual conversion between the client-side signals and the optical signals at a WDM system-compliant standard wavelength.
The 11TOM and 52TOM boards support the Cascading and Non-Cascading modes.
NOTE:
- In Cascading mode, a maximum of eight multi-rate (< 2.5 Gbit/s) Any services can be input to the 11TOM or 52TOM board through the client side, and then are multiplexed into different timeslots of one or two ODU0 services or one ODU1 service.
- In Non-Cascading mode, a maximum of eight multi-rate (< 2.5 Gbit/s) Any services can be input to the 11TOM or 52TOM board through the SFP module on the client side, and then are multiplexed into different timeslots of one to eight ODU0 services or one to four ODU1 services.
NOTE: A specific service signal flow of the 52TOM board is available only when both the board working mode and port working mode are set to specific values.
