Hi all,
I am working as a transmission support engineer for a telecom operator where we use the ericsson milink TN R3 as our transmission system.

I am curently having problems where some NPUs (NPU3) do not pass ethernet traffic but TDM traffic flows without a problem. When the NPU card is reset, the traffic will flow for some hours and then hangs again. No alarms are displayed. All configurations have been checked and compared to those working without any problem and they all look fine. I do not suspect the NodeBs as resetting the card seems to clear the problem temporarily.
What could be causing this scenario? Has anyone experienced this before?

Thanks
