Hi, Вадим, Tomi thank you for your answers.

I suspected toolchain from early beginning because two years ago I managed
to make things work.
I primarily followed procedure from  this link
http://bb.osmocom.org/trac/wiki/Tutorials/CalypsoBTS.

When I do steps with OsmoBTS:

*git clone git://git.osmocom.org/osmo-bts.git
<http://git.osmocom.org/osmo-bts.git> *

*cd osmo-bts
autoreconf -i
./configure --enable-trx
make
sudo make install*

Then I can't use *osmo-bts.cfg* in this form:

*bts 0
 band DCS1800
 ipa unit-id 1801 0
 oml remote-ip 127.0.0.1
 rtp jitter-buffer 0
 paging queue-size 200
 paging lifetime 0
 fn-advance 30
 ms-power-loop -60
 timing-advance-loop
 settsc
 setbsic
 trx 0
  rxgain 0
  power 0
  slotmask 1 0 0 0 0 0 0 0*

specified from mentioned URL.

Also new OsmoBTS binary is not called *osmobts-trx, *but *osmo-bts-trx* and
expect to use new kind of *osmo-bts.cfg* format.


*Maybe I should checkout some other branch from *


*git clone git://git.osmocom.org/osmo-bts.git
<http://git.osmocom.org/osmo-bts.git>  ?*


*Поздрав,Мирко К.*
