Good Evening,
With the recent commits for the OM2000 protocol, I figured it was time to dust off the RBS2308 and see what would happen. I am using the latest version of DAHDI, with a TE122P T1 card. All osmocom software was pulled yesterday and installed successfully on a machine running Debian Stable.
When OpenBSC starts, all appears normal with regards to bringing the BTS up until the timeslots for the first TRX are being configured. When the timeslots are configured, a protocol error is given for each. If I change trx0/ts0 from the default of CCCH+SDCCH4 to CCCH, that timeslot is successfully brought up, and the BTS transmits. Other configurations (TCH/F, TCH/F, PDCH, SDCCH8, TCH/F_TCH/H_PDCH) on timeslots 1-7 give the same protocol error.
I have attached my openbsc.cfg, the output from the OpenBSC console, a pcap of the failed startup, and my DAHDI configuration. If they do not come through the list server, they are also available at: http://cleb.org/RBS/
Thanks,
Caleb
