Hi,
I figured out that the issue is in connectivity between BSC and BTS. I am able to fix half of the issue. I would appreciate any further guidance.
Firstly, I ran only BTS module. In the BTS log, I see an OML connection established. Transcribed are the logs.
<0017> control_if.c:911 CTRL at 127.0.0.1 4238
<0010> telnet_interface.c:104 Available via telnet 127.0.0.1 4241
<0012> input/ipaccess.c:1024 enabling ipaccess BTS mode, OML connecting to
127.0.0.1:3002<000b> trx_if.c:1174 phy0.0: Open transceiver
<0012> input/ipa.c:128 127.0.0.1:3002 connection done
<0012> input/ipaccess.c:846 received ID_GET for unit ID 1800/0/0
<000b> trx_if.c:185 phy0.0: No satisfactory response from transceiver(CMD POWEROFF)
It again fails to get any response.
Next, I ran the combination of TRX-UHD module and BTS module. I failed to get even OML connection.

<0010> telnet_interface.c:104 Available via telnet 127.0.0.1 4241

<000d> abis.c:142 Signalling link down
<0001> bts.c:292 Shutting down BTS 0, Reason Abis close

I could see only this in trace.
Thanks for the help.
