Issue with getting service in GSM network


#1

Hello

I have a GSM network, which has all the local settings ok 3 CDUs and 3 DTRUs one in each

Adding 3 sectors

TX is ok if alarms are synchronized.

The service does not go up and the DXU does not exit the local mode.

What can I do to get the service up and out locally?

You can get a DXU that is working and then u compare the config

Does the DXU light show local or operational


#5

Local. I suspected DXU, but the local technician relocated the same DXU on another site and it worked, and the configurations were tested and passed on ok.


#6

So can’t take the DXU on the working site test on the site with a problem?

Led blinking

Is the light not stable yet?
