Hi, Thankyou for your response. For installation of osmo-bts we are following the instructions at http://openbsc.osmocom.org/trac/wiki/network_from_scratch . Kindly inform which branch should we use?

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

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 -- Best regards, Andy
