Hi!
I've committed the first working version of OpenBSC with vty-based configuration file to the 'config_file' branch in git.
Using this version, all parameters such as BTS E1 card / timeslot / sub-slot / TEI for OML and RSL, MNC, MCC, BSIC, TSC as well as the physical channel configuration of each Um timeslot can be configured in openbsc.cfg.
As an example, I'm attaching a configuration for two bts with two trx each.
You can change the configuration interactively by using the telnet interface by a sequence of commands like: ================ enable configure terminal network bts 0 trx 0 arfcn 111 write file ================
At this point you still need to restart OpenBSC, as we don't support changing configuration at runtime yet.
