OSN3500 cross-clocking board provides service scheduling, clock input and output, and other functions in the OptiX OSN system. The single board supports functions and features such as service scheduling, clock input and output. It accomplishes 200Gbit/s VC-4 high-order crossover, 20Gbit/s VC-3/VC-12 low-order crossover, and 155Gbit/s access capability. The cross-clock board provides timing information to other single boards in the system, realizes the aggregation and scheduling of various services, and completes the communication with other single boards in the system and the configuration management of other single boards. It provides flexible service scheduling capability, supports non-blocking full cross, multicast and broadcast services. Supports SNCP protection at VC-4-4c, VC-4-8c, VC-4-16c, VC-4-64c, VC-4, VC-12, VC-3 and AU-3 levels. Supports 40 linear multiplexed segment protection groups. Supports 12 ring-multiplexed segment protection groups. Supports 2016 SNCP protection pairs. Supports 592 SNCMP protection pairs. Supports 512 SNCTP protection pairs. Supports 1+1 hot backup of single-board crossover and clock unit, and the protection mode is non-recovery by default.The low-order crossover capacity of OptiX OSN equipment determines the low-order access capacity of the equipment. You need to consider the low-order crossover capacity of the device when configuring services.

Operating Procedures

Double-click the Main Topology icon in the Workbench view to enter the main topology diagram.

In the main topology, select the network element icon, right-click it, and select "Network Element Manager".

In the Function Tree, select "Configuration > Cross-Capacity Management > Query Low-Level Cross-Capacity".

Click Query. You can get the "Maximum Capacity", "Maximum VC4 Count", "Remaining Source VC4 Count", "Remaining Host VC4 Count" and "Remaining Host VC3 Count" of the single board. "and "Number of Remaining Host VC3s" and so on.
