There are two variants implemented in the OsmoBTS A-bis dialect:
==== ip.access style Dynamic Channels
==== IPA Style Dynamic Channels
This method is used when OML uses 'NM_CHANC_IPAC_TCHFull_PDCH' (0x80)
as channel combination for the given time-slot.
When the ip.access style dynamic channel combination _TCH/F or PDCH_
'IPA style' refers to 'ip.access' compatible PDCH activation and deactivation.
When the IPA style dynamic channel combination _TCH/F or PDCH_
is set, the non-standard 'PDCH ACTIVATE' (<<pdch_act>>) and 'PDCH
DEACTIVATE' (<<pdch_deact>>) procedures are used for switching an idle
channel into PDCH mode and back into idle mode.
