Hello
I am trying to use openbsc with usrp x310. I have configured and executed osmo-trx from(
https://github.com/osmocom/osmo-trx) and osmo-bts(https://github.com/osmocom/osmo-bts) and
I can see the network on my phone but can't register to it, though I have set auth
policy to accept-all. I have attached attached my config files for reference.

I never used that one personally.

it would be quite useful if you could generate pcap files of the relevant interfaces,
.e.g. in particular the Abis RSL (tcp port 3003) interface.
Please also note you appear to be using openbsc (OsmoNITB) which is no longer supported
for about two years now. Nevertheless, at least network registration should for sure
work.
Regards,
Harald

Hello Harald
Thanks for your Response!!!
Since there was clipping happening on Osmo-trx, I was not able to connect. Changing the
gain helped.
Regards

this is very typical behaviour with other Ettus SDR that I have used
when the clock is not accurate.
do you have the optional internal GPSDO with your x310?
If you have the GPSDO, make sure it is locked.
If you do not, you may not be able to have a very satisfactory
experience unless you can find another stable clock source.
What models of phone have you tried? I found some did not care so much
about the clock.
If no GPSDO, then try putting the phone into manual selection mode, then
power cycle close to your Ettus x310 so the phone sees a string signal
from it.
Quickly manually search for networks and select your network. Watch the
osmo-bts (telnet to port 4241) log output (can't remember which log
level right now, but even log level all debug should be ok) for any sign
of comms from your phone.
