HUAWEI CSHUA SL91 Hybrid Packet Routing control switching and timing board
Product Description:
The functional versions of the CSHUA is SL91.
Application:
CSHUA boards function as system control, switching, and timing boards on OptiX RTN 950 NEs building L3VPNs. In this scenario, these boards forward users' IP service packets. CSHUA boards can also function as system control, switching, and timing boards on Hybrid/Packet radio networks and time division multiplexing (TDM) radio networks like CSHU boards.

Functions and Features:
The CSHUA 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 CSHUA supports.
Table 1 Functions and features that the CSHUA supports
| Function and Feature | Description | |
| Basic functions | Switching capability | Provides a 10 Gbit/s packet switching capacity. |
| Cross-connect capacity | Supports VC-12/VC-3/VC-4 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. | |
| IEEE 1588 ACR | Supported | |
| External clock port | 1 | |
| External time port | 2 | |
| Data communication network (DCN) | Outband DCN | Supports a maximum of 13 data communication channels (DCCs). |
| Inband DCN | The DCN bandwidth is configurable. | |
| Network management protocols | Huawei embedded control channel (HWECC) protocol | Supported |
| IP protocol | Supported | |
| L2 DCN | Supported | |
| Simple Network Management Protocol (SNMP) | Provides the SNMP Get and Set functions for managing devices, excluding configuring L3VPN services. | |
| NE virtualization | Supported. An NE housing CSHUA can function as the master NE in an NE virtualization application. | |
| Multiprotocol Label Switching (MPLS)/Pseudo wire emulation edge-to-edge (PWE3) functions | Supported | |
| See Table 2. | ||
| Native IP | Supported. | |
| See Table 5 | ||
| EBGP Option A | Supported. | |
| Anti-Theft Function | Supported. | |
| Hierarchy VPN functions | Supported. The NE can function only as a cell site gateway (CSG). | |
| See Table 3 | ||
| Quality of service (QoS) functions | Supported | |
| See Table 4. | ||
| Protection | 1+1 hot standby | Supported |
| Auxiliary ports and management ports | NMS port | 1 |
| NMS serial port | 1 | |
| NE cascade port | 1 | |
| Outdoor cabinet monitoring port | 1 The port specifications comply with RS-485. | |
| Mini USB port | 1 This USB management port allows an NE to be connected to and maintained by a Web LCT-installed computer. | |
| Type-A USB port | 1 Connects to a USB flash drive, which can be used to back up/restore databases and upgrade NE software. Houses a WLAN module to implement wireless NMS access. | |
| OM | Warm reset and cold reset | Supported |
| In-service FPGA loading | Supported | |
| Queries of board manufacturing information | Supported | |
| Queries of the board power consumption | Supported | |
| Board temperature monitoring | Supported | |
| Board voltage detection | Supported | |
| Detection of indicators on the other boards | Supported | |
| Hot swapping | Supported | |
The packet switching unit of the CSHUA can work with a service board to implement MPLS/PWE3 functions. Table 2 provides details about these functions.
NOTE4:
Functions described in Table 2 apply only to PWE3 services.
