AW: Why TDM time slot time duration is 577us ??

576,92307692307692307692307692308us per slot 4615,3846153846153846153846153846 per 8 slots (1 frame) 120ms per 26 frames ________________________________ Von: openbsc-bounces(a)lists.gnumonks.org [mailto:openbsc-bounces@lists.gnumonks.org] Im Auftrag von Nataraju A B Gesendet: Freitag, 7. Januar 2011 13:46 An: openbsc(a)lists.gnumonks.org Betreff: Why TDM time slot time duration is 577us ?? Hi All, I wish I am posting this query to the right mailing list. If not please let me know the correct list for this query. I understand the basics of GSM and wireless in general. I have a very basic question. Why did the time slot value considered to be 577us ? I searches Google for some useful doc, which clarifies the reason behind selection of time slot ? Thanks, Nataraju A B

AW: applying multibts-patch
by Andreas.Eversberg 07 Jan '11

07 Jan '11

you don't need that patch. you can configure the hfcmulti.ko using dmask and bmask: * dmask and bmask: * NOTE: One dmask value must be given for every HFC-E1 card. * If omitted, the E1 card has D-channel on time slot 16, which is default. * dmask is a 32 bit mask. The bit must be set for an alternate time slot. * If multiple bits are set, multiple virtual card fragments are created. * For each bit set, a bmask value must be given. Each bit on the bmask * value stands for a B-channel. The bmask may not overlap with dmask or * with other bmask values for that card. * Example: dmask=0x00020002 bmask=0x0000fffc,0xfffc0000 * This will create one fragment with D-channel on slot 1 with * B-channels on slots 2..15, and a second fragment with D-channel * on slot 17 with B-channels on slot 18..31. Slot 16 is unused. * If bit 0 is set (dmask=0x00000001) the D-channel is on slot 0 and will * not function. * Example: dmask=0x00000001 bmask=0xfffffffe * This will create a port with all 31 usable timeslots as * B-channels. * If no bits are set on bmask, no B-channel is created for that fragment. * Example: dmask=0xfffffffe bmask=0,0,0,0.... (31 0-values for bmask) * This will create 31 ports with one D-channel only. * If you don't know how to use it, you don't need it! hope this helps -----Ursprüngliche Nachricht----- Von: openbsc-bounces(a)lists.gnumonks.org [mailto:openbsc-bounces@lists.gnumonks.org] Im Auftrag von Thomas Ansorg Gesendet: Freitag, 7.

[ADM] OpenBSC git repository address change
by Harald Welte 07 Jan '11

07 Jan '11

Hi all! Today, I have moved the remaining projects on git://openbsc.osmocom.org/ (aka git://bs11-abis.gnumonks.org/) to the central git://git.osmocom.org/ location. This helps us to consolidate all our git repositories on one server. The git URL of the main OpenBSC repository has changed from git://bs11-abis.gnumonks.org/openbsc.git (read-only) gitosis@bs11-abis.gnumonks.org:openbsc.git (write) to git://git.osmocom.org/openbsc.git (read-only) gitosis@git.osmocom.org:openbsc.git (write) In order to update your local repository with the new URL, simply use the "git remote set-url" command, like in the following examples. for those of you with read-only access: git remote set-url origin git://git.osmocom.org/openbsc.git for people with write/commit access: git remote set-url origin gitosis@git.osmocom.org:openbsc.git The other two repositories that have changed in similar way are openggsn.git and chan_openbsc.git. Thanks for your attention, and sorry for any inconvenience, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Wireshark Patching...
by Omar Atia 06 Jan '11

06 Jan '11

Dear All, Please note that after getting the sources using git , I found wireshark directory contains patches ? I did some googling I found that if I need to patch wireshark I should run like the below command : 1. patch -p1 < patch path/name the configure and compile , but while checking wireshark sources I didn't find for packet-gsm_abis_oml.c in the path of wireshark /epan/dissectors? does the patch abis_oml.patch(available under wireshark directory with the delivery downloaded with git) create it ? Thanks, Omar Atia

IPA Stream IDs
by Holger Hans Peter Freyther 06 Jan '11

06 Jan '11

Hi all, I was very liberal in just using numbers from the 'open' number range. We should move to a different scheme and just take the liberty to take one ID and then have our own header inside there. I would propose to do something like this struct ipa_proto_hdr { uint16_t len; uint8_t proto; data[0]; } packed; struct osmo_ipa_proto_hdr { uint8_t osmo_proto; data[0]; } packed;. Any comments?

Dear All, Can you advise how I could make connections to real MSCs from Openbsc ? Is it supported by OpenBSC? I believe it is over A protocol right ? SCCP ? Thanks, Omar Atia
