Product Details

HUAWEI CSH SL92 Hybrid Packet control switching and timing board


Product Description:

The functional versions of the CSH are SL91 and SL92.

Compared with the SL91CSH, the SL92CSH incorporates the following new functions:

MPLS-TP tunnel OAM

ETH PWE3 packets carrying control words

Supporting a backplane bus of 2.5 Gbit/s (only when the service boards are EG4/EG4P boards)

Supporting virtual private LAN services (VPLSs)


Application:

CSH boards function as system control, switching, and timing boards on OptiX RTN 950 NEs building Hybrid/Packet radio networks. In this scenario, these boards also groom TDM services and Ethernet services. Like CST boards, CSH boards can function as system control, switching, and timing boards on OptiX RTN NEs building TDM radio networks.

Application of CSH Boards on NEs Building Hybrid Radio Networks

Figure 1 Application scenario of CSH boards (1)


NOTE:

IF boards shown in the preceding figure must be general-purpose IF boards or XPIC IF boards working in native E1+Ethernet mode or native STM-1+Ethernet mode.

Service boards shown in the preceding figure can be E1 interface boards, STM-1 interface boards, or Ethernet interface boards.

NOTE:

IF boards shown in the preceding figure must be general-purpose IF boards or XPIC IF boards working in native E1+Ethernet mode or native STM-1+Ethernet mode.

Service boards shown in the preceding figure can be Smart E1 processing boards or Ethernet interface boards.


Functions and Features:

The CSH provides 10 Gbit/s packet switching, full time-division cross-connection, system control and communication, and clock processing functions. It provides auxiliary ports and management ports.


Table 1 lists the functions and features that the CSH supports.

Table 1 Functions and features that the CSH supports

Function and FeatureDescription
Basic functionsSwitching capabilityProvides a 10 Gbit/s packet switching capacity.
Cross-connect capacitySupports VC-12/VC-3/VC-4 full time-division cross-connections (equivalent to 32x32 VC-4s).
System control and communicationManages, 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.
ClockClock 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 Synchronous

Supports IEEE 1588v2 time synchronization.

Supports ITU-T G.8275.1 time synchronization.
