laforge gerrit-no-reply at lists.osmocom.orglaforge has submitted this change. ( https://gerrit.osmocom.org/c/osmo-bsc/+/24911 ) Change subject: add test_dyn_ts_favor_static_ts_as_target.ho_vty ...................................................................... add test_dyn_ts_favor_static_ts_as_target.ho_vty In a discussion about the effect of interference levels, I noticed that there is not sufficient clarity about how strongly the preference of static timeslots is ranked. This test helps to show what we have.
