Dear List,
I tried to set up Osmo-CBC with a Nokia MetroSite BTS according to the wiki. But every time the CBSP clinet of the BSC connects to the CBC server, the BSC log indicates:
DCBS cbsp_link.c:150 CBSP Client connected to CBC: (r=127.0.0.1:48049<->l=127.0.0.1:46133) DCBS smscb.c:805 (bts=0) Rx CBSP RESET: clearing all state; disabling broadcast
Same time on the CBC:
<0002> cbsp_link.c:265 New CBSP link connection from 127.0.0.1:46133 <0002> cbsp_link_fsm.c:181 local-bsc: RESTART (CBS) but re-sending not implemented yet
The BTS is configured with CCCH+SDCCH4+CBCH, and these are the relevant sections:
osmo-cbc.cfg:
cbc unknown-peers reject ecbe local-ip 127.0.0.1 local-port 12345 cbsp local-ip 127.0.0.1 local-port 48049 sbcap local-ip 127.0.0.1 local-port 29168 peer cbsp local-bsc mode server remote-port 46133 remote-ip 127.0.0.1
osmo-bsc.cfg:
cbc mode client client remote-ip 127.0.0.1 local-ip 127.0.0.1 local-port 46133
Every other CS service is working fine on the BTS.
Is there anything else I might have missed?

Hi Sipos,
I fail to see which is exactly the problem you have. Can you describe what you expect instead of what you are getting?

Hi Pau,
When I use the command: ./cbc-apitool.py create-cbs --msg-id 4370 --payload-data-utf8 "Bon giorno!"
Nothing happens. I thought the issue is with the link between the CBC and the BSC due to this message in the logs. The phone has a CBC app which is running, but nothing is displayed.

Hi,
"nothing happens" is a bit too vague. Can you at least share a pcap file ?

Hi,
I cant share a pcap atm, but I enabled debugging for RSL and CBS, and this is how that looks:
Tue Sep 26 11:52:32 2023 DCBS cbsp_link.c:150 CBSP Client connected to CBC: (r=127.0.0.1:48049<->l=127.0.0.1:46133) Tue Sep 26 11:52:32 2023 DCBS cbsp_link.c:193 Received CBSP RESET Tue Sep 26 11:52:32 2023 DCBS smscb.c:973 CBSP Rx RESET Tue Sep 26 11:52:32 2023 DCBS smscb.c:805 (bts=0) Rx CBSP RESET: clearing all state; disabling broadcast Tue Sep 26 11:52:32 2023 DCBS smscb.c:211 (bts=0) Success Tue Sep 26 11:52:43 2023 DCBS cbsp_link.c:193 Received CBSP WRITE-REPLACE Tue Sep 26 11:52:43 2023 DCBS smscb.c:860 CBSP Rx WRITE_REPLACE (CBS) Tue Sep 26 11:52:43 2023 DCBS smscb.c:681 (bts=0) BASIC Added MsgId=0x1112/SerialNr=0x7000/Pages=1/Period=5/NumBcastReq=999 Tue Sep 26 11:52:43 2023 DCBS smscb.c:211 (bts=0) Success
after this on RSL only "Rx Resource Indication" messages, and CBSP keep alives.
Based on this I would say the Osmo-CBC does sends the message to the BSC, and nothing happens between the BSC and the BTS.

The log looks fine.
If you look at the RSL from BSC to BTS you should see the related smscb sent to the bts.
