hytera BS and TETRA ******** DEVICE REBOOTING

[andreas_haf]

Hello there
i am experience a problem with several ******** devices operating in trunk mode under a HYTERA BS.
we have several times a day the devices rebooting. while they are in idle or talking in the network the devices makes 3-4 times a reboot and operating ok.
The devices are operating in trunk mode with our a problem but once or two times in a 24hour clock they start rebooting

the strange think is that they are rebooting all together like receiving a trigger which makes them to reboot.
from the BS site we have check everything and we can not find any faults
Any suggestions for the ******** devices programing?
any one how has experienced the same problems?

Hi Andreas,

Do you know what is the Hytera Tetra PV release used on BS (advanced DIB-R5) ? Nothing special in MNC-511 log ?

What are the ******** radio models concerned ? what firmware revision used ? Any special features enabled on them ?

Check logs of your on-site UPS. E.g. APC SmartUPS will show you graph of VAC including drops. It might be a reason as well.
