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
