From the CS perspective, there is no difference whether this is a dynamic TS in NONE/PDCH mode or a static TCH in UNUSED mode since BSC can switch into USED mode at any moment. So we should count dynamic timeslots in the "total" count. A bit of a challenge here is that GSM_PCHAN_TCH_F_TCH_H_PDCH timeslots could be either switched to a single TCH/F or to two TCH/H, so the total can't be calculated reliably beforehand. In this code we assume TCH/F since this gives a lower total count. Change-Id: Iabd70e8adbf15eb3b7a7be597281ea99b352317b |

About OsmoBSC ============= OsmoBSC originated from the OpenBSC project, which started as a minimalistic all-in-one implementation of the GSM Network. In 2017, OpenBSC had reached maturity and diversity (including M3UA SIGTRAN and 3G support in the form of IuCS and IuPS interfaces) that naturally lead to a separation of the all-in-one approach to fully independent separate programs as in typical GSM networks. OsmoBSC was one of the parts split off from the old openbsc.git. Before, it worked as a standalone osmo-bsc binary as well as a combination of libbsc and libmsc, i.e. the old OsmoNITB. Since the standalone OsmoMSC with a true A interface (and IuCS for 3G support) is available, OsmoBSC exists only as a separate standalone entity. OsmoBSC exposes - A over IP towards an MSC (e.g. OsmoMSC); - Abis interfaces towards various kinds of BTS; - The Osmocom typical telnet VTY and CTRL interfaces.
