Hi, When having a look at http://discourse.criticalengineering.org/t/howto-gsm-base-station-with-the-b eaglebone-black-debian-gnu-linux-and-a-usrp/56 I wonder if there is a way to use the osmo-trx with rangenetworks RAD1/SDR1 radio. I do not yet own an Ettus B210, so it would be fun using the BeagleBone with the RAD1/SDR1, what is some shrinked and at the same time extended USRP1 radio. Ralph. -- Ralph A.

Re: TRX Clock calibration

by Alexander Chemeris

Choukoumoun, The question is related to the osmo-trx more than to UmTRX, so I'm moving it to the Osmocom mailing list: On Tue, Jul 15, 2014 at 8:17 PM, choukoumoun <choukoumoun(a)gmail.com> wrote: > Hello guys. > > I have a UMTRX my UHD/OPENBTS or UHD/OSMO-TRX same working fine but wen i > start osmo-trx and openbts i have this error Could you specify where did you get sources and which exact versions and commit numbers do you use?

The issue with "UHD: Device send timed out" have nothing to do with the VCXO calibration. The issue is because of a issue in communication between the host system and the UmTRX. What is your hardware setup? Particularly: - Do you use a switch between the UmTRX and the host system? - Do you run it on a real hardware or in a VM? - Is your host system powerful enough? -- Regards, Alexander Chemeris.

[RFC/PATCH] tlv/msgb: Be able to generate and parse TLV as used by LLDP

by Holger Hans Peter Freyther

Hi! we have the need to generate and parse LLDP frames and would like to use the TLV infrastructure of libosmocore for it. In LLDP the tag is only 7bit and the length is 9bit long. To make this work with the tlv parsing routines we need to shift the tag. But this means that when somebody is a tlv_definition with the T7L9 type and others we might match the wrong thing. I would like to include the feature as it is right now. The alternative would be to create a separate tlv_parse and tlv_parse_one routine for the other type. comments? holger

AFAIK, this branch is not being used in real environments, so it's most likely bit-rotten. My suggestion is to take the implementation there as an inspiration and re-implement it for master. That would make a good work for one of your students probably. Please don't move the conversation into private and keep the mailing list CC'ed. -- Regards, Alexander Chemeris.

Need help with configuration of Timeslots and of multible USRPs

by Norbert Englberger

Hello everybody, after starting on my new Job at an University I have been tasked to build up an BTS for our students. Being a complete noob to both Linux and GSM it took me some time, but I finally got OpenBSC and Osmo-BTS up and running on Ubuntu Linux 12.04 with our ETTUS N210. After doing some experiments with this setup, our students now ask me to do some changes which I couldn't figure out yet, how to do. 1. The students told me, that OpenBSC doesn't behave like all the BTS from commercial Providers they analysed: The say that on commercial nets at the beginning of a phone call there will be send an "Immediate assignment" sending the MS always to a SDCCH on TS 1 or TS2 where the encryption will be startet. After establishing the encryption another "Immediate assignment" will occour and send the MS to a Traffic Channel (which also contains the FACCH / SACCH) for the actual Communication. OpenBSC also sends the "Immediate assignment" on TS0 but sends the MS directly to Timeslot with a Traffic Channel where all the signalling, like encryption, will be done in the SACCH. Is there any way to configure OsmoBSC to behave like the commercial BTS the students described? 2. I have been asked if I could enable "Frequency Hopping" Right now I already fail to bring up a second TRX with OpenBSC. I start 2 instances of "osmo-trx" with 2 differents IP-Addresses but the same port, after that I start "osmobts-trx" with the "-t 2" parameter. OpenBSC seems to see both USRPs but the LED'S an the USRPs indicate that only one is completely powered up and transmitting (a quick check with an Motorola with RSSI also shows only one ARFC). So how do I have to start "osmo-trx" to enable transmitting on both URSPs as TRX0 and TRX1 in one BTS? After that, is it possible to configure "Frequency hopping" with this setup? (Because when I changed the value "hopping enabled" of the timeslots in open-bts.cfg to "1" I get a message that this type of BTS does not support hopping) I hope that anyone can clarify those two points to me. Thanks in advance Norbie

I was hoping that it would be enough to change the settings in the open-bsc.cfg and I wouldn't have to temper the source code, as I said, I'm new to all the GSM stuff and Linux. I had a quick look at the code and just tried to comment out everything in "get_ctype_by_chreq" and always return LCHAN_SDCCH as you suggested. While testing this setup I saw, that The "Immediate assignment" now sends the calling MS to TS 1 (which is configured as SDCCH/8) subslot 0 and starts encryption and sends SI5 and SI6 messages on this timeslot/subslot. Also the called MS gets "Immediate assignment" and is sent to TS 1 subslot 1, encryption starts and so on. Now the called MS sends "Call Confirmed", but shortly after this the channels are released. (The called MS wasn't ringing at all) Am I right, that this is because both MS are yet sticking on the SDCCH and are not going to a Transport channel? (would make sense, because I always return SDCCH when the BSC wants to change channel) I think I have to change the Table " ctype_by_chreq" or to find a way to insert another "Immediate Assignmend" between "encryption" and "call confirmed" So I think I'll have to study the source code for a while, Again thanks for the hint where to start.
