AFAIU, 'osmotrx tx-attenuation' in osmo-bts.cfg allows you to override
the attenuation value sent by the BSC. It should be set to 'oml' by
default, meaning that the BSC controls attenuation (via A-bis/OML).

P.S. This mailing list is more about the mobile side of the GSM stack,
not core network. Please use openbsc at lists.osmocom.org for questions
about radio/core network side next time.

With best regards,
