For example there is "oml ..." for the BS-11 and "ip.access ..." for the nanoBTS. So the "oml ..." commands in the config file you posted won't work for the nanoBTS. I have not tried it yet, but thats where I would start to modify the config file for the nanoBTS. Best regards, Dieter -- Dieter Spaar, Germany spaar(a)mirider.augusta.de

Hello guys, Today I've pulled the latest sources and have issues of executing bsc_hack with config file. It complains about: GSM900 channel must be between 1-124. mi_e1_line_update could not open socket Address family not supported by protocol But I changed the config file for the nanoBTS1800, is there something missing?

SCCP: State of the current implementation
by Holger Freyther 14 Aug '09

14 Aug '09

Hey Guys, this is just a small note of the current work in the holger/on-waves-msc-sccp branch. The goal of this branch is to implement A over IP and hook OpenBSC into a real GSM network. This work is on the way thanks to on-waves.com. The current state: - Partially implemented SCCP. We can send UDT messages, and full connection handling exists. I have not implemented segmenting for DT1 yet and will try to avoid doing that. - Split out vty_interfaces into two parts. One for the MSC functionality and one for the BSC - Split out gsm_subscriber into two sets. One for BSC and one for MSC. - Do not compile gsm_04_08.c but provide the layer2->layer3 ourselves with moving shared stuff to gsm48_utils.c. This way creating and parsing of messages can be shared and the policy can remain in the old file. (this is the biggest change to earlier approaches). What will be next: - Use bsc_msc_ip.c to initialize the the tcp connection, do the handshaking, start sending the reset as seen in the traces. What can be merged: - I think I will propose to merge the vty and gsm subscriber changes after HAR2009 as they have little chance to break stuff. z.

nanoBTS
by WoMax 12 Aug '09

Hi! I've got a few nanoBTS, type 139 and 140. So I need just one, the others are now for sale. Type 140(1900), you don't disturb the existing providers, for 1300 euro, working well with all quadband handsets. Type 139(1800) for 1200 euro. All equipment is in working order, supplied with PoE-Adapter. If you buy 2, there is a 10% off. The Unit's are located in Switzerland and can be picked up here on Lake Constance or shipped by german post, so you don't have to pay for expensive shipment like from US. BTW I can't reach Harald Welte by email to ask him where is my ordered BS-11. Regards, -- - Thomas Mueller <womax(a)gmx.ch>

One bug in bsc_hack.c
by Holger Freyther 10 Aug '09

10 Aug '09

Hey, I compiled with -Wall -Werror and fixed the easy ones. While doing it I encountered one bug in the bsc_hack.c.. int ipaccess_setup(struct gsm_network *gsmnet) is called with a struct gsm_bts*... The current ipaccess_setup need to be called once per network (as we should only bind to the address once...). any idea what to do? z.

[PATCH 0/1] Add bport0/1 support for bs11_config
by Daniel Willmann 09 Aug '09

09 Aug '09

Hello, this patch should add support to bs11_config for bport0/1 configuration. This should enable you to configure a BS11 to run in multidrop mode and so contol two BS11 from one E1 link. I only have one BS11 so I was only able to verify that the objects are indeed created/modified. If it's okay I can also directly push the patch.

Your problem might be related to the actual cabling. I believe it is definitely a layer1 (cabling) or layer 2 (mISDN) problem. I don't really know any other advice but to double-check the cabling, the jumpers on the E1 board as well as the termination jumpers on the BS-11. Everything has to be set to 120 Ohms. -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

OpenBSC with configuration file
by Harald Welte 07 Aug '09

07 Aug '09

Hi! I've committed the first working version of OpenBSC with vty-based configuration file to the 'config_file' branch in git. Using this version, all parameters such as BTS E1 card / timeslot / sub-slot / TEI for OML and RSL, MNC, MCC, BSIC, TSC as well as the physical channel configuration of each Um timeslot can be configured in openbsc.cfg. As an example, I'm attaching a configuration for two bts with two trx each. You can change the configuration interactively by using the telnet interface by a sequence of commands like: ================ enable configure terminal network bts 0 trx 0 arfcn 111 write file ================ At this point you still need to restart OpenBSC, as we don't support changing configuration at runtime yet. -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Ericsson RBS 2308
by Harald Welte 04 Aug '09

04 Aug '09

Hi! JFYI: I've bought an Ericsson RBS 2308 a couple of days ago, this is a BTS with traditional E1 interface, but with GPRS + EDGE support. I've managed to find the manual online at http://rapidshare.com/files/178080402/RBS2308.rar I have not yet received the unit, but there are more availalbe by a seller based in Texas / USA (USD 750). I can't promise that OpenBSC will have good support anytime soon, but I'll definitely look into it.
