    HUAWEI CSHD SLA1 Hybrid Control Units Switching And Timing Board

    HUAWEI CSHD SLA1 Hybrid control units switching and timing board


    Product Description:

    The functional version of the CSHE is SLA1. The functional versions of the CSHD are SLA1 and SLA2.

    Compared with the SLA1CSHD, the SLA2CSHD incorporates the following new functions:

    Multiprotocol label switching transport profile (MPLS-TP) tunnel OAM

    ETH pseudo wire emulation edge-to-edge (PWE3) packets carrying control words

    Virtual private LAN services (VPLSs)


    Application:

    CSHD/CSHE boards function as system control, switching, and timing boards on OptiX RTN 910 NEs building Packet radio networks. In this scenario, these boards also receive and transmit E1/FE/GE services. Use CSHE boards if fixed GE electrical ports are required (for example, to achieve synchronous Ethernet or IEEE 1588v2 functionality). Otherwise, use CSHD boards if possible.

    Figure 1 Application scenario of CSHD/CSHE 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.

    Ethernet ports on CSHD/CSHE boards can carry MPLS tunnels, which allow CSHD/CSHE boards to transmit MPLS/PWE3 services traversing radio networks and regional backhaul networks in end-to-end mode.

    Like CSHA/CSHB/CSHC boards, CSHD/CSHE boards can function as system control, switching, and timing boards on OptiX RTN NEs building Hybrid radio networks. If IEEE 1588v2 packets need to be transmitted using Ethernet ports on system control, switching, and timing boards, CSHD/CSHE boards must be installed.


    Functions and Features:

    The CSHD/CSHE provides 4.4 Gbit/s packet switching, full time-division cross-connection, system control and communication, and clock processing functions. The CSHD/CSHE provides FE/GE ports, E1 ports, auxiliary ports, and management ports.


    Table 1 lists the functions and features that the CSHD/CSHE supports.

    Table 1 Functions and features that the CSHD/CSHE supports

    Function and FeatureDescription
    Basic functionsSwitching capacitySupports 4.4 Gbit/s packet switching function.
    Cross-connect capacitySupports full time-division cross-connections (equivalent to 8x8 VC-4s) at the VC-12, VC-3, or VC-4 level.
    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 to help the NMS to control and manage the NE.
    ClockClock source

    Provides the system clock and frame headers for service signals and overhead signals for the other boards when tracing an appropriate clock source.

    The traced clock source can be any of the following:

    External clock
