hello, built 2 bs11 interconnect cables + termination today. but the second bs11's not recongnised. i tried the 2-2 cfg-file, and mine. i want to use only one trx per bts. my cfg-file look like this: ! ! OpenBSC configuration saved from vty ! ! password foo ! line vty no login ! network network country code 262 mobile network code 10 short name T-Net long name Test-Netz timer t3101 10 timer t3113 60 bts 0 type bs11 band GSM900 cell_identity 1 location_area_code 1 training_sequence_code 7 base_station_id_code 63 oml e1 line 0 timeslot 1 sub-slot full oml e1 tei 25 trx 0 arfcn 121 max_power_red 0 rsl e1 line 0 timeslot 1 sub-slot full rsl e1 tei 1 timeslot 0 phys_chan_config CCCH+SDCCH4 e1 line 0 timeslot 1 sub-slot full timeslot 1 phys_chan_config TCH/F e1 line 0 timeslot 2 sub-slot 1 timeslot 2 phys_chan_config TCH/F e1 line 0 timeslot 2 sub-slot 2 timeslot 3 phys_chan_config TCH/F e1 line 0 timeslot 2 sub-slot 3 timeslot 4 phys_chan_config TCH/F e1 line 0 timeslot 3 sub-slot 0 timeslot 5 phys_chan_config TCH/F e1 line 0 timeslot 3 sub-slot 1 timeslot 6 phys_chan_config TCH/F e1 line 0 timeslot 3 sub-slot 2 timeslot 7 phys_chan_config TCH/F e1 line 0 timeslot 3 sub-slot 3 bts 1 type bs11 band GSM900 location_area_code 2 training_sequence_code 7 base_station_id_code 63 oml e1 line 1 timeslot 4 sub-slot full oml e1 tei 25 trx 0 arfcn 122 max_power_red 0 rsl e1 line 1 timeslot 4 sub-slot full rsl e1 tei 1 timeslot 0 phys_chan_config CCCH+SDCCH4 e1 line 1 timeslot 5 sub-slot 0 timeslot 1 phys_chan_config SDCCH8 e1 line 1 timeslot 5 sub-slot 1 timeslot 2 phys_chan_config TCH/F e1 line 1 timeslot 5 sub-slot 2 timeslot 3 phys_chan_config TCH/F e1 line 1 timeslot 5 sub-slot 3 timeslot 4 phys_chan_config TCH/F e1 line 1 timeslot 6 sub-slot 0 timeslot 5 phys_chan_config TCH/F e1 line 1 timeslot 6 sub-slot 1 timeslot 6 phys_chan_config TCH/F e1 line 1 timeslot 6 sub-slot 2 timeslot 7 phys_chan_config TCH/F e1 line 1 timeslot 6 sub-slot 3 i modified the 2-2 cfg file in a way that made sense to me. when i connect only the 2nd bs11 to the pc, it isnt recognised as well. firmware is on, an due to people who works there, this bs11 was once operational. did i forget any setup procedures maybe? 2nd problem: bs11_config i tried bs11_config -p /dev/ttyUSB0 as described in the page, but seems this device ttyUSB0 doesnt exist.the lmt cable is connected and telnet localhost 4242 from other console also works. 3rd problem: during bsc_hack running, i get strange messages. my 2 favorites are: gsm04_08.c: 873 location updating reject on channel 0 abis_nm.c:1799 Invalid channel combination!! is there any faq or something else, where these messages are explanined? answers in german preferred. increases enormously the readability on my pc.

AW: Optional cell reselection parameters setting
by Andreas.Eversberg 29 Nov '10

did you push it? my head of sylvain/testing is: commit cbf5ba125a70bd18c5919d51203d836fd26fa98a [WIP] Voice IND -----Ursprüngliche Nachricht----- Von: openbsc-bounces(a)lists.gnumonks.org [mailto:openbsc-bounces@lists.gnumonks.org] Im Auftrag von Sylvain Munaut Gesendet: Sonntag, 28. November 2010 20:58 An: OpenBSC list Betreff: Optional cell reselection parameters setting Hi, I've just pushed a patch in sylvain/testing with vty commands (and support code) to support settings things such as the Cell Reselection Offset (which is in the re tst octet). If someone could just have a quick look before I put it in master. The main thing is the vty setting to support things like: penalty time <20-620> penalty time infinite I had to create two commands it seems (can specify that an arg is either a range or a keyword if I'm not mistaken). Cheers, Sylvain

nanoBTS and power settings
by Matthew Harper 28 Nov '10

28 Nov '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi There, It occured to me the other day that I have been spending many hours sat next to my nanoBTS in a lab environment and have never given thought about the amount of power that the device is outputting. Looking through the bsc_hack config settings I can see the ms max power setting, at present I have this setting set to 15. I am also not sure at which levels to set my nominal power and max_power_red settings. What are everyone's opinions on a safe power setting at which to set the nanoBTS? Is 15 to high or low? What do other people have there power settings set too? Does anyone have any reading material on the wider health implications of using such a device as the nanoBTS in close proximity to a person for long periods of time? Many thanks for the help, advice and suggestions.

A problem in OpenBSC, sccp.c
by Wenbin Wu 26 Nov '10

26 Nov '10

Hello, I have a problem in sccp.c. 537--543 udt->type = SCCP_MSG_TYPE_UDT; udt->proto_class = class; udt->variable_called = 3; udt->variable_calling = 5 + out->gti_len; if(out->use_poi) udt->variable_calling += 2; udt->variable_data = 7 + out->gti_len + in->gti_len; if(in->use_poi) udt->variable_calling += 2; I add these two 'if' lines in the code. I'm not sure if it is right. In source code, before it calls 'create_sccp_addr', it sets the length only using gti_len. But in 'create_sccp_addr', if I use poi, the length should be add 2. Am I right?

Hello, This is a test to see if I can make it to the mail list. And a little question: If one wants to get involved in development, how does one get a hold of some hardware?
