Strange nanoBTS Behavior
by Max Marbler 23 Apr '11

23 Apr '11

Dear List, I'm a long time listener, first time caller - but have been enjoying experimenting with OpenBSC for a little while now. I've come across a new (to me) nanoBTS with some strange behavior: it seems to come up normally and pull an IP over DHCP, and interacts as expected with the ipaccess-find and ipaccess-config tools, but *never* attempts to establish an OML link. After provisioning the correct settings with ipaccess-config, the unit reboots and slow-flashes the orange light (no OML) and there is *no* network traffic initiated by the nanoBTS past the DHCP exchange; however, I can ping the unit using ipaccess-find and ping. After running a reset with the dongle and a repeat of the above, I get the same results. Any ideas? Thank You, -MM

intra BSC Handover
by Christopher HENARD 21 Apr '11

Hello all, I want a confirmation. I 've seen in openBSC features that openBSC handles handover between cells inside one BSC. So I think it's possible to connect several nanoBTS to openBSC and move from one cell to another without losing the outgoing call. Am I right ? Thank you. Chris

SIM programmer recommendations?
by David A. Burgess 21 Apr '11

21 Apr '11

All - I am looking for a full-card SIM programmer to use with pySim and GR-Card SIMs. By full-card I mean it accepts a full-size smart-card with the SIM still attached. I have tried the Bludrive II unit provided by GR-Card under both Mac OS X and Ubuntu with no luck. (And yes, I tried downloading and installing the drivers.) Can anyone recommend something that is known to work with pySim under Linux or OS X? Or is there some other driver that I need to install or configure? -- David

bsc_hack
by Christopher HENARD 20 Apr '11

Hi everyone, I have successfully compiled and installed openBSC-0.9.13, but there isn't the program bsc_hack. However, in src/osmo-nitb, there's bsc_hack source code and object (.c and .o) and an executable osmo-nitb. Has bsc_hack been replaced by osmo-nitb ? Thanks. Christopher Hénard

Blocks OpenBSC the calls to 112?
by Luca Bertoncello 19 Apr '11

19 Apr '11

Hi, List! Just a question, does OpenBSC block the connection to special number such 112? I connected OpenBSC to Asterisk and in Asterisk I have an extension 112 (now just as test), an 110 and an 115. If I call the 110 or 115 I can see that Asterisk will be asked to connect the phone and the VoIP-phone with the number will be called. If I call the 112 the connection terminates and I can't see OpenBSC sending any signal to Asterisk. Could you confirm me, that OpenBSC blocks this number? And, maybe, suggest me how to delete this block... :) Thanks a lot!

> Does it mean, that it is not possible for me to have a 112 number b > called in my network? No, it's not possible. You should avoid anything starting by '1' and anything starting by '9' in your dialplan ... Cheers, Sylvain

What is the purpose of the "RF cable"? > Is the TX port of the master BTS looped through the second BTS? Or hase > every nanoBTS his own TRX/RX? The RF cable is used to route TX from the rear unit to the AUX connector of the front unit. The SMB socket at the back and AUX are directly connected, there is nothing special about them. So in a stacked two-units assembly the front unit also has the TRX antenna of the rear unit at the AUX connector. Most certainly the idea is to improve transmission of the rear unit or to better separate the two TRX antennas. So TX is looped through one unit but the two TX signals are not combined.
