Hello,
I have a nanoBTS from ipaccess. I used ipaccess-config to set the
Unit-ID of the nanoBTS and also the Primary OML IP address. Everything
worked OK and OpenBSC and the nanoBTS where communicating.
My problem now is that I want to connect the nanoBTS back to my
original BSC (from Zynetix). By using ipaccess-config I set the OML IP
address back to what it was originally but the unit does not connect
to the original BSC.
I have two other nanoBTS's and their Unit-ID is 65535/255/255 before
they 'sign up' to the BSC, where they get another Unit-ID. I've tried
using ipaccess-config to set the Unit-ID to that value but get an
error: "Failure to set attribute. This seems fatal"
Does anyone know how I can reset the Unit-ID to 65535/255/255 ?
Best regards,
Bjarni S. Sigurdsson
Hi,
I'm currently implementing Early Assignment in the On Waves branch and as part
of this I will have to take care of RSL channel releases as well.
Someone else was pointing this out as well but I could not find the email. Our
channel release is a bit sloppy and I will fix it and start using T3111 and
T3109 in the rsl code for doing so.
In the "normal" case (bsc on the left, bts on the right):
RSL Channel Release -->
<- RSL Channel Release Ack
<- Release Indication SAPI=0
RSL Channel Release ->
<- RSL Channel Release Ack
In the "abnormal" case:
<- Error Indication
RSL Channel Release ->
<- RSL Channel Release Ack
<- Release Indication SAPI=0
RSL Channel Release ->
<- RSL Channel Release Ack
I'm going to change that into the following way.
"normal" case:
1.) Release the established SAPIs
2.) After their ACKs release the Channel
Have all this guarded by T3109 (or whatever is more appropriate)
"abnormal" case:
1.) Start T3109
2.) Then do the normal case.
During the shutdown sequence I need to make sure that we are not allocating
the channel again. I'm thinking of either using the chan mode Harald was
introducing while doing the hand over work, or just a "locked" flag to not
assign the channel.
I hope to be done with this by tomorrow or the day after, anyone has comments
or ideas on how to approach this?

Hi,
i have problems bringing up the second TRX. I used the following procedure:
./bs11_config -p /dev/ttyUSB0 disconnect
./bs11_config -p /dev/ttyUSB0 create-trx1
After reboot the query tells me:
./bs11_config -p /dev/ttyUSB0 query
LMT LOGON: ACK
PHASE: 3 Normal MBCCU0: Load MBCCU1: Load Abis-link: Restoring
...
BS11 Power Amplifier 0 ATTRIBUTES:
TRX Power: 30mW (GSM)
LMT LOGOFF: ACK
Now i wondered where is the trx1, did anyone has a similar problem? I have the BS-11 ESN PCB Serial Number: 001127 which should have two TRX.
Greets & thx Till
