Hi,

I looked at the forum for answers before posting, but I
unfortunately couldn't get answers to what I was looking for. I looked into
particular
https://www.mail-archive.com/openbsc@lists.osmocom.org/msg09819.html for
solving my issue.

Setup: USRP B210 as radio head. NITB modules as components for 2G Network
and BTS-TRX and TRX-UHD modules.
Issue:

   - TRX-UHD and BTS-TRX fail. NITB Module works. Components of NITB
   network are able to connect to each other.
   - I have the RSP POWEROFF message originating in log from TRX-UHD module
   and the BTS module is shuttiing down.
   - BTS connects via OML but fails to connect RSL.
   - As per the previous email archive, I wanted to login to VTY and check
   the logs, but, it logs out as the BTS module shuts down (I cannot connect
   and see what's happening).

I looked through the configuration files and seem correct to me.
Any suggestions would be appreciated on solving the issue. I am trying to
create a test 2G OSMOCOM network. Logs are written below and configuration
as attachments.

Thanks for your help!
