OpenBSC with Dahdi+Asterisk and several BTS

historical

Hi Ellen,

here is how I start OpenBSC without any BTS.

cd openbsc

src/osmo-nitb -c doc/examples/osmo-nitb/nanobts/openbsc.cfg -C

and make sure the current directory is not write protected.

Then I start the telnet terminal with:
telnet localhost 4242

Hope this helps.

Br,
Michael
