[srsran-users] N310 srsran example NSA/ RF status: O=4, U=74, L=2

Tue Nov 22 00:39:15 UTC 2022

Hi Juan Carlos and Oriol,

Thanks for your response! We are trying to implement 5G SA E2E tests. The
computer is set to performance mode and it should be powerful enough, but
we are just using the 1 GBE module, because we don't have a 10 GBE module.
We will try to get one and redo the tests then.

Thanks,
