This timer is started when a channel is allocated with an IMMEDIATE ASSIGNMENT message. It is stopped when the MS has correctly seized the channel. Ever since the early days of development we were using a very long timeout to be on the safe side. However, in production networks this is a terrible waste of resources, as we will occupy 10s worth of air-time on one of our channels for each RACH request we receive. The only scenarios where you might need something absurdly high as 10s would be if you have 8s of RTT between your BTS and the BSC.

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.
