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. | |
