Huawei SSN1IXCSA Board Product Overview Huawei SSN1IXCSA Board is an infinite cross clock board. It provides service scheduling, clock input and output functions in the OptiX OSN 3500 system, flexible service scheduling capabilities, non-blocking full crossover, multicast and broadcast services, and Communication function Huawei SSN1IXCSA Board can be configured through the T2000 network management system. The parameters that the IXCSA board needs to set through the network management are as follows: no external clock and SSM is not enabled, the following parameter configuration, clock reference source, clock source tracking level, external clock configuration, and SSM enable are required. Clock reference source, clock source tracking level, clock can work in the following modes: lock mode, hold mode, free oscillation mode, type of external BITS: set S1 byte, select the threshold of the clock switch protection action. Brand Huawei Model SSN1IXCSA Basic function Higher order cross capability: 200Gbit / s Low-order crossover capability: 40Gbit / s Access capability: 155Gbit / s, Service Provides flexible scheduling capabilities for services, supports non-blocking full crossover, and supports multicast and broadcast services. Provides communication functions with other boards. Supports micro-switches to achieve smooth protection switching of the cross-board. Support VC-4-4c, VC-4-8c, VC-4-16c, VC-4-64c, VC-4, VC-12, VC-3 and AU-3 SNCP protection. Supports VC-4-4c, VC-4-8c, VC-4-16c, and VC-4-64c cascade services. Supports up to 40 linear multiplex segment protection groups. Supports up to 12 ring multiplex segment protection groups. Supports up to 8064 SNCP protection pairs. Supports up to 592 SNCMP protection pairs. Supports up to 512 SNCTP protection pairs. Protection method Supports 1 + 1 hot backup of the board crossover and clock unit, and the protection mode is non-recovery by default. Huawei SSN1IXCSA Board Product Features Huawei SSN1IXCSA Board provides 155G access capacity, the SSNIIXCSB board provides 156.25G access capacity, the high-order (VC4) cross-connect capability is 200G, and the low-order (VC12 / VC3) cross-connect capability is 40G. The SSN1IXCSB’s 1.25G capacity is the access capacity of the extended subrack. Huawei SSN1IXCSA Board has flexible service scheduling capabilities. It can implement services such as the cross, broadcast, multicast, and loopback among services, and it can also implement protection functions such as SNCP and MSP. Huawei SSN1IXCSA Board implements the system timing function. Can be selected and configured from two external sources (2MHz or 2Mbit / s, and supports 75 ohm and 120-ohm interfaces), clock sources sent from 15 business boards, as the clock source for phase-locking, or the board The crystal oscillator free oscillation output is used as the clock reference. The board has the function of processing the status byte of the synchronization information.
