HUAWEI CSHNA SLB1 Hybrid system control switching and timing board Product Description: The functional version of the CSHNA is SLB1. Application: The CSHNA is the hybrid system control, switching, and timing board for the new-generation OptiX RTN 980. It provides STM-1, STM-4, and GE ports to convergence and schedule various types of services. Figure 1 Application of CSHNA boards NOTE: E1 services shown in the preceding figure can be native E1 services or CES/ATM E1 services, and Ethernet services can be native Ethernet services or ETH PWE3 services. Service boards shown in the preceding figure can be Ethernet interface boards, STM-1 interface boards, E1 interface boards, or Smart E1 processing boards. Functions and Features: The CSHNA provides 43 Gbit/s packet switching, full time-division cross-connection, system control and communication, and clock processing functions. It provides GE/FE ports, STM-1/4 ports, auxiliary ports, and management ports. Table 1 lists the functions and features that the CSHNA supports. Table 1 Functions and features that the CSHNA supports Function and Feature Description Basic functions Switching capacity Provides a 43 Gbit/s packet switching capability. Cross-connect capacity Higher order cross-connect capacity: 128x128 VC-4s Lower order cross-connect capacity: VC-12/VC-3 full time-division cross-connections equivalent to 32x32 VC-4s System control and communication Manages, monitors, and controls the running status of the IDU, and works as a communication service unit between the NMS and boards, thereby allowing the NMS to control and manage the NE. Clock Clock source Provides the system clock and frame headers of service signals and overhead signals for the other boards by tracing any of the following clock sources: External clock SDH line clock PDH tributary clock Microwave link clock Synchronous Ethernet clock Clock protection Supports the following clock protection schemes: Protection based on clock source priorities Protection by running the SSM protocol Protection by running the extended SSM protocol Time synchronization Supports IEEE 1588v2 time synchronization. Supports ITU-T G.8275.1 time synchronization. Supports use of the AE 905S module as the clock source for time synchronization. IEEE 1588 ACR Supported External clock port 1 External time port 2 Data communication network (DCN) Outband DCN Supports a maximum of 24 DCCs. Inband DCN Supports the inband DCN function. The DCN bandwidth is configurable.
