Hi Amber & Sarosh,
UmTRX itself can with with both channels in different bands.
That said, this is not currently implemented in OsmoBTS/OsmoNITB - you can
see that the band is specified for a BTS as a whole. Patches to add this
feature are very welcome.

Hi,
Thank you for your help Alexander.
We have configured our system to use both the channels of UmTRX on
different ARFCNs of GSM900 band with OsmoNITB, OsmoTRX and OsmoBTS.We have
a Fairwaves UmTRX version 2.2 with us. Can you please confirm if the two
channels of a single UmTRX can be configured to operate on two different
bands for example one channel on GSM900 and the other one on DCS1800?

Amber & Sarosh

Amber & Sarosh,
We recommend using the following branches:
osmo_trx: fairwaves/master
libosmocore: master
libosmo-abis: fairwaves/master
libsmpp34: master
osmo_bts: fairwaves/debian
openbsc: fairwaves/master
Let us know if you have any issues using them.

Amber & Sarosh,
It looks like you're using a wrong version of osmo-bts. Whuch branch
and commit are you using?
