Hi,
I looked at the forum for answers before posting, but I
unfortunately couldn't get answers to what I was looking for. I looked into
particular
https://www.mail-archive.com/openbsc@lists.osmocom.org/msg09819.html for
solving my issue.
Setup: USRP B210 as radio head. NITB modules as components for 2G Network
and BTS-TRX and TRX-UHD modules.
Issue:
- TRX-UHD and BTS-TRX fail. NITB Module works. Components of NITB
network are able to connect to each other.
- I have the RSP POWEROFF message originating in log from TRX-UHD module
and the BTS module is shuttiing down.
- BTS connects via OML but fails to connect RSL.
- As per the previous email archive, I wanted to login to VTY and check
the logs, but, it logs out as the BTS module shuts down (I cannot connect
and see what's happening).
I looked through the configuration files and seem correct to me.
Any suggestions would be appreciated on solving the issue. I am trying to
create a test 2G OSMOCOM network. Logs are written below and configuration
as attachments.
Thanks for your help!

Hello Aalto,
your configuration looks good to me. As far as I understand, you're
running both osmo-bts-trx and osmo-trx on the same machine. As can be
seen from your logs, TRXC commands from osmo-bts-trx are received by
osmo-trx:
<0002> Transceiver.cpp:778
[tid=140554180474624][chan=0] command is 'POWEROFF'
however the response messages from osmo-trx do not reach osmo-bts-trx:
<0002> Transceiver.cpp:923
[tid=140554180474624][chan=0] response is 'RSP POWEROFF 0'
<000b> trx_if.c:185 phy0.0: No satisfactory response from transceiver(CMD POWEROFF)
Maybe your firewall is blocking traffic (udp/5701 and udp/5801)
somehow? Could you please send us a *.pcap capture ('lo' interface)?
With best regards,
Vadim Yanitskiy.

Hi Vadim,
Thank you for your quick replies. (Previously, due to error, I sent reply
to you. Now, I have resent with openbsc in cc)
I wasn't sure, if my firewall is blocking the port or not. Hence, I took a
wire shark trace test.pcap. I ran sudo ufw allow 5701 and sudo ufw allow
5801 and then again took wire shark trace test2.pcap. Both traces are
attached. From my inspection, the ports have still the same messages.
I am also attaching the configuration of other components, as a reference.
Thanks again for the help

Hi again,
Hence, I took a wire shark trace test.pcap.
I see ICMP Destination Unreachable messages in your captures:

Perhaps you're starting osmo-bts-trx before osmo-trx? Make sure to
start osmo-trx first and give it enough time to upload the UHD
firmware, unless you see "Transceiver active with X channel(s)".
With best regards,
Vadim Yanitskiy.

New subject: OSMOCOM TRX_BTS_BSC Connection Issue
Hi,
I have the feeling the connection between osmo-trx and osmo-bts-trx is
good. The problem is that your BTS<->BSC<->... is failing.
BTs shows these messages at startup because osmo-trx is not yet running:
""""

osmo-bts-trx[23221]: <000b> trx_if.c:185 phy0.0: No satisfactory
response from transceiver(CMD POWEROFF)
"""
Then at some point osmo-trx answers:
"""

But it's already too late, the BTS is already exiting due to some issue

New subject: OSMOCOM TRX_BTS_BSC Connection Issue
Hi Aalto, Pau,
The problem is that your BTS<->BSC<->...
is failing.
I don't see any related packets in the captures, neither RSL nor OML...
However, I see an obvious issue - IPA unit-id mismatch:
# This is the unit id that has to match the BTS
configuration
ip.access unit_id 1800 0
vs
ipa unit-id 6969 0
Are you using some configuration examples? If so, where are they from?
Also, are you sure that osmo-bsc is actually running on 192.168.122.1?
With best regards,
Vadim Yanitskiy.

Hi Vadim and Pau,
Thank you for the quick replies.
*Pau:* Probably your guess is correct. I am looking into it in detail at
the moment the core network configurations.
*Vadim*: I started osmo-trx first and waited until the message "Transceiver
active with 1 channel(s)", before running osmo-bts-trx and other modules.
I will look into the wireshark capture to ensure that there are RSL and OML
packets. Yes. I am using the configuration examples from
*https://osmocom.org/attachments/3473/nitb.tar
<https://osmocom.org/attachments/3473/nitb.tar>.* I am not sure, how to
test osmo-bsc is actually running on 192.168.122.1 (I guess, I have to ping
to ensure). Meanwhile, is there a basic configuration where I can run the
system? Can I find it somewhere(I tried to run /usr/local/etc/osmocom
config files and it didn't work. Probably, I have to fine tune the
configurations)? And, is there a wireshark trace by any chance for
reference?

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

<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.

New subject: OSMOCOM TRX_BTS_BSC Connection Issue
Hi,
Sorry to bother you all again. I am stuck with this since a week trying to
figure out, but failing so. I am able to see OML in wireshark
traces(attached as a picture), but still not able to see RSL protocol.
I need to be able to connect bts-trx and bsc modules to get a working
connection. Any suggestions would be appreciated.
Thanks for the help.

Hi,
your png image clearly shows that you have some problem with AoIP side
(SCTP connections failing). Are you running osmo-stp and osmo-msc?
It's useless trying to help you better if you don't provide at least
config files and a pcap with all the generated traffic while start and
running your network.
