Nordin bouchtaoui at gmail.com> (1) With which type(s) of BTS does OpenBSC work? > Check the in bsc_hack.c : handle_options(), it will finally leads you to gsm_bts_type() in gsm_data.c and there you can find the struct bts_types. For now it supports nanobts900/1800 and bs11. > (2) What is OML NM? > OML stands for Organization and Maintenance Layer, it has a broad meaning, but in this case it's for configuring the BTS. Actually it's more for managing and configuring the network. Maybe other guys can give better explenation about OML NM. > (3) What is the best way to follow the path in the code in case of a call? > Well, you should know that the whole communication is based on select(). All socket connection and traffic is based on select(). When select is called, it blocks untill a certain amount of time or an event occurs on one of the provided file-descriptors. It than searches in a list (Linux-doublylinked-list) which FD caused an event and than the appropriate function will be called to handle it further (callback-function). In case of a call you might look at rsl layer.
