Industrial 4G routers Under what circumstances will alarm information be issued

- Sep 26, 2018 -

⑴ Four slides per 24 hours for any input 2048kbit/s digital signal, resulting in a general alarm. The critical alarm for the frequency regulation range of the


⑵ phase-locked loop. A general alarm is emitted due to the aging of the clock crystal, which causes the inherent clock frequency to deviate from the control range of the phase-locked loop (control signal exceeding three-fourths of the clock adjustment range).


⑶ The industrial-grade All-network router loses the input frequency base for 10 minutes or a continuous error frame for 10 minutes to produce a general alarm. 


⑷ routers if one of the frequency benchmarks fails or drops, a general alarm should be generated. If all the input frequency reference failure or quality should produce a serious alarm.

 

⑸ for any input 2048kbit/s digital signal, every 24 hours, this number is equal to or more than 255 times to produce a serious alarm.

 

⑹ Industrial CDMA routers lose a frequency base of 24 hours or a continuous error frame for 24 hours to produce a serious alarm.


⑺ The clock itself fails, such as a constant temperature tank failure, a clock stop, and a serious alarm.
