Hello Alex,

Thank you so much for your reply!! I am able to see IMSI in TMSI table now!
but still my phone is not connecting to network.

I tried installing OsmoTRX using following commands

$ git clone git://git.osmocom.org/osmo-trx

$ autoreconf -i

$ ./configure
$ make
$ sudo make install
$ osmo-trx -f

after last command my transceiver enables

In OpenBTS CLI it gives
OpenBTS> noise
noise RSSI is --2147483648 dB wrt full scale
MS RSSI target is -50 dB wrt full scale

OpenBTS> version
release TRUNK+GPRS P built May 16 2016 rev8925M

OpenBTS> power
current downlink power -1 dB wrt full scale

OpenBTS> tmsis
TMSI       IMSI            age  used
       1 001010000000003    6m    6m

but in OsmoTRX terminal i am getting
WARNING 3032677184 13:31:00.0 Transceiver.cpp:674:pullRadioVector: Clipping
detected on received RACH or Normal Burst
WARNING 3032677184 13:31:00.0 Transceiver.cpp:674:pullRadioVector: Clipping

and still my phone is not registering to network
It is showing same message!

Thanks & Regards
Anuja
