SST2UXCSA and SST1SXCSA board is OptiX OSN 7500 system cross connection with the clock processing board, done in the middle business system scheduling and timing system two big functions.
SST2UXCSA board with 280 g access capacity, higher order crossover capability is 300 g, low-order VC12 / vc33 intersection capacity of 20 g.
SST1SXCSA veneer with 280 g access capacity, higher order crossover capability is 320 g, low-order (VC12 / vc33) cross capacity of 40 g.
SST2UXCSA or SST1SXCSA board and flexible business operation ability, can realize the business between cross, broadcast, multicast, ring back, and other functions, and can realize SNCP, MSP protection function etc.
SST2UXCSA or SST1SXCSA board implementation system timing function. Single board has the function of processing synchronization information status byte. Cross the clock plate in the system using 1 + 1 hot backup protection, greatly improve the reliability of the system.
SST2UXCSA and SST1SXCSA board does not support extended frame.
SST2UXCSA/SST1SXCSA board of the main functions and features are: form of equipment type configuration, network configuration, protection configuration; Realize the business of flexible scheduling, including the loopback, cross, multicast, broadcast;Synchronous clock for other business system board system, system frame synchronization signal; The function of the sync processing status byte; The choice of source of external timing functions, and outside to the system output 2 MHZ or 2 mbit/s of timing signal; At the same time, support 75 ohms and 120 ohm interface double plate hot backup job, automatic rearrangement of the event of a failure to prepare the work board plate work, business of failure recovery;Through the RS485 bus and the LAN SWITCH bus communication with other board.
Configuration SST2UXCSA or SST1SXCSA cross clock plate OSN7500 system has a large capacity of access and business operation ability, can be used to access the large capacity node and multiple overlapping nodes system.All kinds of typical network mode and the way of network protection can be achieved
