Since 2009, Chengxiao Technologies has released PTN devices from 3G to 960G. The products are widely used in government-enterprise networks such as mobile backhaul, fiance, transportation and so on.

    Chenxiao Technology's PTN equipment has several notable features.
       1. The hardware implementations the G.8113.1 and G.8113.2 of the OAM standard. The device supports dual stacks at the same time.
       2. Hardware-implemented protection switching protocol, the whole protocol is implemented by FPGA, does not require CPU to participate in protocol operation, and shortens the time of protection switching.
      3. Perfect protection switching mechanisms, including CFP, MSP, LSP/PW liner protection, LSP-RING, Dual-homing, VP-APS, VPN-FRR, IP-FRR, VRRP etc.
      4. Hardware implementation aids the implementation of PTP protocol, which can send a large number of 4ms periodic PTP messages accurately.
      5. Support static L3VPN to satisfy X2/S1 traffic guidance
