Thanks for pushing ahead here.

That's of course odd.  But it should be rather easy to investigate if
looking at an Abis or A-interface trace?  I think we recently had an
issue that we'd only use SDCCH for LU and never fall back to "bigger"
channels like TCH.  Maybe that's limiting your LU rate, particularly if
you only have a SDCCH/4?
