Dear Experts

I have failed to get the AMF value from the usim programmer as he said that
he can't find this in his data (He said that the other commercial operators
are using the his usim and its working fine).

However, I could manage another uhd module (B200 series)   and testing the
srsue for connecting the other machine running srsepc and srsenb using
another B210.

I am yet to be successful in the new setup. please, see the attached files
and ith suggest me what should be done to overcome this disconnection
issue. [I used the default conf file for both the machine except the nrb= 6
instaed of 25 in enb.conf]

With regards.
