Aalto Koskinen aaltokoskinen at gmail.comHi, 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.
