Re: Jumper settings for 120 Ohm connection

Maybe there is something wrong with the wire connection. If you can see the signal sent from the E1 card at the BS-11 and there is also a signal sent from the BS-11, than probably the signal from the BS-11 is not received by the E1 card so it could not synchronize on it.

Jumper settings for 120 Ohm connection
by Holger Adams 02 Mar '09

02 Mar '09

Hello Everybody, I'm just trying to connect the E-1 host card to the BS-11, but I can't get it work. The serial connection works fine, I'm also seeing the "Abis-link: Restoring" message. My hardware configuration: 1) I removed the green jumpers TB01 - TB04 2) Jumper settings below the Twinax-board: 1-4 ON, 5-8 OFF 3) HFC-E1: NT Mode, Config A (all jumpers on the left side to the left) 4) 'hfcmulti' modprobed with 'dslot=1' 5) Forced the BS-11 to use correct TEI and E1 slot by using 'bs11_config' Have I missed something? I put a scope upon the rx/tx pins - traffic flows into both directions, so I think there's no collision (tx->tx, rx->rx) Thanks, Holger

The polarity does not care, you can exchange TX+ with TX- and RX+ with RX-. A simple test for just the correct wire without connection the BS-11: - On the cable which goes to Y01 you should be able to see a signal with an oscilloscop between TX+ and TX-. - If you connect the two TX lines with the two RX lines (loopback, polarity does not care), the card should synchronise and the LEDs should not longer blink. Attention: I have tested this on Windows only, with a loopback, I can see that the card synchronises, however I don't know what mISDN does, but I guess it will also synchronise. If this works, you know that the cable is OK. Best regards, Dieter -- Dieter Spaar, Germany spaar(a)mirider.augusta.de

Harald on holidays
by Harald Welte 28 Feb '09

28 Feb '09

Hi All! I'll be on holidays pretty much throughout the time from March 4th through March 25th. I will check my email only in very irregular intervals, particularly not after March 11. I will try to get back to any inquiries after I have returned. Meanwhile, the list (particularly subscribers like zecke, dieter spaar, nibbler and others) will hopefully be able to adress all issues you might have.

Initial Config BS-11
by Rene Stegmaier 24 Feb '09

24 Feb '09

Hi Folks, yesterday i´ve tried to do the initial config of my BS-11. But i have a problem after warmup while querying the BS-11: rene@nb-stegmaier:~/data/development/bs-11/svn/trunk/openbsc/src $ ./bs11_config -p /dev/ttyUSB0 query bs11_config (C) 2009 by Harald Welte and Dieter Spaar This is FREE SOFTWARE with ABSOLUTELY NO WARRANTY LMT LOGON: ACK PHASE: 1 Software required Abis-link: Down No valid Safety Load file "BTSBMC76.SWI" PHASE: 1 Software required Abis-link: Down No valid Safety Load file "BTSBMC76.SWI" Whatis going wrong? I read in the wiki that the projekt doesn't provide any firmware images, but how can i get the BS-11 working? Is there any way to generate this "Safety Load file" and upload it to the BS-11? cheers, René -- Rene Stegmaier <rene(a)rr47.de> LAN-TEX Schuberstr. 14 38518 Gifhorn Mobil: 01703183653

Tektronix K1103 pinout of the E-1 interface
by Holger Adams 22 Feb '09

22 Feb '09

Hello Everybody, we have several Tektronix K1103 protocol analyzers standing around here and it was quite complicated to get the pinout of the SUB-D 9 connectors. Monitor A: Pin Purpose 9 RX+B 4 RX-B 6 RX+A 1 RX-A 2,3,4 GND A = E-1-Linecard -> BTS B = BTS -> E-1-Linecard Monitor C: 9 RX+D 5 RX-D 6 RX+C 1 RX-C 2,3,4 GND Telephone socket: 1 mic input (-) 2 hearer output (+) 3 hearer output (-) 4 mic input (+) Factsheet of this analyzer: http://www2.tek.com/cmswpt/psdetails.lotr?ct=PS&lc=EN&ci=14411&cs=psu Holger

BS11 getting started instructions
by Harald Welte 22 Feb '09

22 Feb '09

hi! I've put together a new page at http://bs11-abis.gnumonks.org/trac/wiki/BS11_Getting_Started which explains the individual steps from unpacking the BTS, verifying its configuration using bs11_config up to connecting and getting it up and running with a HFC-E1 Eval Board and the bsc_hack program. Once again, feel free to add information to the wiki, I will happily provide accounts to every user!

OpenBSC mailing list / installation questions
by Harald Welte 22 Feb '09

22 Feb '09

Hi! I'm sending this mail to all recent buyers of a BS-11. I would like to ask you to raise any questions you might have regarding setup/configuration/installation of the BS-11 unit or OpenBSC at the openbsc(a)lists.gnumonks.org mailing list. You can subscribe to the list online at https://lists.gnumonks.org/mailman/listinfo/openbsc The benefit of asking your question at this list is that other BS-11 / OpenBSC users and developers will see your questions and learn from the answers or at some point even provide the respective answers themselves. I would also want to invite you to contribute to our wiki at http://bs11-abis.gnumonks.org/. We do not allow public editing, so if you want an account, just email me privately and I will send you username and password. I hope we can now finally start to build a community around the project, with some 30 BS-11 distributed to various GSM enthusiasts all over the world.

bs11_config doesn't build right now
by Harald Welte 19 Feb '09

19 Feb '09

Hi! Some of you have already received their BS-11 and built the power cord for it. Next step is to obviously try bs11_config on the serial port. Unfortunately it doesn't build right now since I restructured some shared code. I'll work on this tonight, should be fixed soon. -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
