Performances
   Embedded processor, support high-speed processing protocol and large data flow
   100% dial-in success rate when powered on
   Stability: 7x24 hour, except network problem, no disconnection to be caused by design deficiency of the equipment
   100% redial success rate after disconnection
   In UDP mode and on a high transmission speed (sending a 256B data pack every 5s), pack-loss rate is below 3%
   With unstable power supply which breaks off frequently, redial success rate is 100%, dial in  time is 30s~80s
