[PATCH] bugfix: additional functionality indicator only appears in TP_VPF_ENHANCED

by Steffen 'stefreak' Neubauer

The patch is attached ("bugfix"). You can simply merge the stefreak/trivia branch (but there is one more change in it, see the second patch attached. abis_nm.c was executable, that's a really trivial change). Greetings, Steffen

Re: Issues on initial setup with BS-11

Can you check the "PLL set" and "PLL work" values with bs11_config ? If the BS-11 is locked to the E1 clock, it could be that the clock of the BS-11 is too far away from the correct value so that a phone will only find the official networks but not the one of the BS-11.

I think the problem is the "Invalid Channel Combination!!!" error message. Try to change "phys_chan_config" of timeslot 1 from "SDCCH8" to "TCH/F". From my understanding of verify_chan_comb() "SDCCH8" is not allowed on the same TRX that already has "CCCH+SDCCH4" so I wonder why it is set in the config file (this only applies to the BS11). Sorry, I don't have a ready BS11 configuration at hand right now, so I can't test it. Best regards, Dieter -- Dieter Spaar, Germany spaar(a)mirider.augusta.de

Issues on initial setup with BS-11

by s4dd＠losers.yore.ma

Hello all, I seem to have fallen at the last hurdle to achieving my first milestone - being able to see an available network from our BS-11/OpenBSC combi on a variety of MEs. Fingers crossed it's something trivial that has been overlooked. I've included some output from bs11_config and bsc_hack below in the hope that someone may spot the issue. Output from bs11_config during bootup: PHASE: 1 Load SMU Intended Abis-link: Down PHASE: 1 Load SMU Intended Abis-link: Down PHASE: 2 Load MBCCU MBCCU0: No Load MBCCU1: No Load Abis-link: Down PHASE: 2 Load MBCCU MBCCU0: Load BTSCAC MBCCU1: No Load Abis-link: Down PHASE: 2 Load MBCCU MBCCU0: Load BTSCAC MBCCU1: Load BTSCAC Abis-link: Down PHASE: 2 Load MBCCU MBCCU0: Load BTSDRX MBCCU1: Load BTSCAC Abis-link: Down PHASE: 2 Load MBCCU MBCCU0: Load BTSDRX MBCCU1: Load BTSDRX Abis-link: Down PHASE: 2 Load MBCCU MBCCU0: Load BTSBBX MBCCU1: Load BTSDRX Abis-link: Down PHASE: 2 Load MBCCU MBCCU0: Load BTSBBX MBCCU1: Load BTSBBX Abis-link: Down PHASE: 2 Load MBCCU MBCCU0: Load BTSBBX MBCCU1: Load BTSBBX Abis-link: Down PHASE: 2 Load MBCCU MBCCU0: Load BTSARC MBCCU1: Load BTSBBX Abis-link: Down PHASE: 2 Load MBCCU MBCCU0: Load BTSARC MBCCU1: Load BTSARC Abis-link: Down PHASE: 2 Load MBCCU MBCCU0: Load MBCCU1: Load BTSARC Abis-link: Down PHASE: 2 Load MBCCU MBCCU0: Load MBCCU1: Load BTSARC Abis-link: Down PHASE: 2 Load MBCCU MBCCU0: Load MBCCU1: Load Abis-link: Down PHASE: 3 Normal MBCCU0: Load MBCCU1: Load Abis-link: Restoring BS11 ATTRIBUTES: SITE MANAGER ATTRIBUTES: E1 Channel: Port=0 Timeslot=1 (Full Slot) TEI: 25 BS11 Line Interface ATTRIBUTES: PLL Mode: E1 Locked BS11 CCLK ATTRIBUTES: BS11 Power Amplifier 0 ATTRIBUTES: TRX Power: 30mW (GSM) LMT LOGOFF: ACK ************************************************************ Output from bs11_config with query: LMT LOGON: ACK PHASE: 3 Normal MBCCU0: Load MBCCU1: Load Abis-link: Up BS11 ATTRIBUTES: SITE MANAGER ATTRIBUTES: E1 Channel: Port=0 Timeslot=1 (Full Slot) TEI: 25 BS11 Line Interface ATTRIBUTES: PLL Mode: Standalone BS11 CCLK ATTRIBUTES: BS11 Power Amplifier 0 ATTRIBUTES: TRX Power: 30mW (GSM) LMT LOGOFF: ACK ************************************************************ bsc_hack startup: DB: Database initialized.

I think this a limitation of the BS11 only, I have read that there are some limitations related to the SDCCH/8 of the BS11: - only one SDCCH/8 per TRX - not allowed together with SDCCH/4 on BCCH-TRX Maybe the BS11 does not have enough processing power to handle it ? Of course it could be that the documentation is wrong and it would work, I have not yet tried it. Best regards, Dieter -- Dieter Spaar, Germany spaar(a)mirider.augusta.de

system_information branch updates

by Harald Welte

Hi! While enroute to FOSS.in in Bangalore, I took the time to test and debug the various issues I could find with the code in the system_information branch. At least in all of my tests, the system information messages, including rest octets and neighbor cell lists are looking perfectly fine. Especially now that with my latest patch, wireshark is able to dissect the SI messages properly, it is much easier to debug :) If you want to give it a try, I recommend using something like git revision 63b152ebb74355acfde76e9ce1113f2d823c0804 of that branch. Please note: We currently only support the relative bitmask format for the neighbor cell lists. That means, you cannot have neighbors with ARFCN's spanning a range of more than 111, i.e. your lowest and highest ARFCN have to be within a distance of 111 ARFCN's. Unless there are major objections, I intend to merge this branch ASAP (or rather do a 'git diff master..system_information' and apply the resulting diff as one commit to master) Regards, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
