NanoBTS Problem

Hi, I have a nanobts config file: ! OpenBSC configuration saved from vty ! password foo ! line vty no login ! network network country code 1 mobile network code 1 short name SomeNet long name SomeNet timer t3101 10 timer t3113 60 auth policy closed bts 0 type nanobts ip.access unit_id 0 0 band GSM1800 location_area_code 1 training_sequence_code 7 base_station_id_code 63 ms max power 40 trx 0 rf_locked 0 arfcn 514 timeslot 0 phys_chan_config CCCH+SDCCH4 timeslot 1 phys_chan_config SDCCH8 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 bsc_hack reports: DB: Database initialized.

Any ideas? Thanks, Stuart
