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?
Regards,
Amber & Sarosh

We recommend using the following branches:osmo_trx: fairwaves/masterlibosmocore: master
libosmo-abis: fairwaves/masterlibsmpp34: master

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

Hi
Thanks for your reply. We have tested the configurations that you mailed but
our setup still produces the following error message when osmobts is run;
<0006> scheduler.c:212 Init scheduler for trx=0
<000a> trx_if.c:485 Open transceiver for trx=0
<000a> trx_if.c:496 Waiting for transceiver send clock
There is no such command.
Error occurred during reading below line:
rxgain 12
Unknown TRX 1. Aavialable TRX are: 0..0
Failed to parse the config file: '/root/.osmocom/osmo-bts.cfg'
Any help in this regard is much appreciated. Thanks.

Hello Amber & Sarosh
You have to add these lines below into /etc/osmocom/openbsc.cfg right after
trx0 configuration
trx 1
rf_locked 0
arfcn 184 (set the right ARFCN for you here )
nominal power 23
max_power_red 0
rsl e1 tei 0
timeslot 0
phys_chan_config TCH/F
timeslot 1
phys_chan_config TCH/F
timeslot 2
phys_chan_config TCH/F
timeslot 3
phys_chan_config TCH/F
timeslot 4
phys_chan_config TCH/F
timeslot 5
phys_chan_config TCH/F
timeslot 6
phys_chan_config TCH/F
timeslot 7
phys_chan_config TCH/F
And add into etc/osmocom/osmo-bts.cfg
trx 1
rxgain 12
power 0
restart services: sudo sv restart osmo-trx osmo-bts osmo-nitb
Regarding trx band dividing, theoretically it might possible but we haven't
tested that
