* RACH for packet service is not equal PRACH. PRACH
is a dedicated
logical channel on the Um interface that _can_ be enabled (like PBCCH,
PCCCH, ...) but whihc is neither supported by osmo-bts/osmo-pcu, nor
used anywhere. The 3GPP removed the PBCCH/PCCCH and all related
channels several years ago from the specs, as there was no operator
known to use any of them. So new handsets no longer (have to) support
those channels, which means it is utterly useless for a new
implementation like the Osmocom one to bother to support them.
Ah, good to know.
Is PTCCH also one of those? It sounds similar, but I guess not?
