Hi All, We want to run two independent ARFCNs on UmTRX using the two TRXs on the device using osmo-bts, but just as trx 0 is defined in osmobts.cfg we cannot define trx 1. Can someone please help us accomplish this? Also please inform if it is possible that we run one TRX on GSM900 and another on 1800? Note: we have compiled the openbsc setup as per instructions at http://openbsc.osmocom.org/trac/wiki/network_from_scratch using the jolly/multi-trx branch. Regards, Amber & Sarosh

Hi Thanks for your reply. We have tested the configurations that you mailed but our setup still produces the following error message when osmobts is run; <0006> scheduler.c:212 Init scheduler for trx=0 <000a> trx_if.c:485 Open transceiver for trx=0 <000a> trx_if.c:496 Waiting for transceiver send clock There is no such command.

Amber & Sarosh, It looks like you're using a wrong version of osmo-bts. Whuch branch and commit are you using? On Mon, Apr 27, 2015 at 5:39 AM, Amber and Sarosh <amber_sarosh(a)hotmail.com> wrote:

Hi, Thank you for your help Alexander.

Hi Amber & Sarosh, UmTRX itself can with with both channels in different bands. That said, this is not currently implemented in OsmoBTS/OsmoNITB - you can see that the band is specified for a BTS as a whole. Patches to add this feature are very welcome.

Jijo, In osmo-bts config you always specify "bts 0". If you need several BTS on the same PC, use different config files for them. You can pass a config file name with a command line option to osmo-bts. All BTS must have different ipa unit-id - that's how they are differentiated in osmo-nitb (openbsc) configuration.

Hi Andy, I already tried the locate command on osmo-trx logs but didn't find anything. Am attaching the open-bsc.cfg(ho_bsc.cfg) file herewith. Hi Alexander, I'm trying to run the multi-BTS configuration as specified in: http://openbsc.osmocom.org/trac/wiki/multi-BTS_with_handover The only difference being that the 1st BTS is running in the same machine as the BSC(osmo-nitb) So I have 1st PC with osmo-nitb(ho_bsc.cfg), osmobts-trx(ho_bts0.cfg) and osmo-trx 2nd PC with only osmobts-trx(ho_bts1.cfg) and osmo-trx Also have you tested the handover with GPRS enabled(osmo-sgsn and openggsn)?? As that is my final objective. Thanks and Regards Jijo

Dear Andy, I used the procedure from http://openbsc.osmocom.org/trac/wiki/network_from_scratch And I installed the versions as specified by you in the previous mails. And it is working now. Dear Alexander, Thanks for the input. Your suggestion worked for the BTS and now I can see both of the BTSs from the OpenBSC console. I had a couple of more questions if you can help with them. 1. How do I initiate a handover and is there any way to see the call flow messages from the terminals ? 2. How do I build the system for GPRS support(OpenGGSN). I did it earlier using the following links http://openbsc.osmocom.org/trac/wiki/OpenBSC_GPRS and https://wush.net/trac/rangepublic/wiki/fairwaves.gprs What is the build version that I should be using for GPRS support? Looking forward to hearing from you. Thanks and Regards, Jijo

Dear Alexander, Which are the packages required to be built for GPRS support in UmDESK? Earlier I had installed only the osmo-pcu and it was working properly. With the newer installation it is not working Currently I've installed libosmocore, osmo-pcu, openggsn, libosmo-abis, osmo-nitb, osmo-bts, osmo-trx and lcr. Does it require the libosmo-netif and the osmo-pcu libraries? I tried installing libosmo-netif package also, and now the osmo-pcu package is not able to detect the BTS at all. Which are the packages required to be run for GPRS? Is there any other links available for this installation with the branch details to be used for GPRS support?
