HUAWEI CSHUA SL91 Hybrid Packet Routing Control Switching And Timing Board

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.
