E1 card oscillator replace, timing accuracy problem
by Sipos Csaba 04 Oct '13

04 Oct '13

Hi Guys, I am working with Nokia InSite and MetroSite units and now it is obvious, that I have a timing accuracy problem with my E1 dahdi card. According to "dahdi_test" I have a magnitude worse accuracy compared to the GSM specs. I can measure 99.995% accuracy compared to the required 99.99975%. MY question is what can I do about it? My first idea was to replace the oscillator on the card, which by default has a 20ppm oscillator on it. I was able to find some 10ppm oscillators but they are not matching the required frequency (8.192MHz). It would be nice to hear some ideas about how can I solve this issue. Thanks! BR, Csaba

[PATCH 0/6] Four minor fixes, "subscriber create" and subscriber's info formatting.
by Alexander Chemeris 04 Oct '13

04 Oct '13

This patch set is mostly minor fixes and clean ups, with the exception of the last two patches ("subscriber create" VTY command and a standard way for printing a subscriber's info). I would appreciate merging this patches to master, as I'm working onmore code which depends on them. Alexander Chemeris (6): Fix copy-paste error in console output in db_test. Fix typo ',' -> ';' at the end of a line. Fix typo in console output: "PEROIDOC" -> "PERIODIC". Slight clean up of the code in gsm340_rx_tpdu() and a fix for an unlikely, but possible memory leak there. Add "subscriber create" VTY command. Introduce a standard way for printing a subscriber's info. openbsc/include/openbsc/gsm_subscriber.h | 4 ++++ openbsc/src/libmsc/db.c | 2 +- openbsc/src/libmsc/gsm_04_08.c | 2 +- openbsc/src/libmsc/gsm_04_11.c | 7 ++++--- openbsc/src/libmsc/vty_interface_layer3.c | 27 +++++++++++++++++++++++++++ openbsc/tests/db/db_test.c | 2 +- 6 files changed, 38 insertions(+), 6 deletions(-) -- 1.7.9.5

How use TCAP instead of DTAP?
by Maicon Kist 03 Oct '13

03 Oct '13

Hi list, I want to integrate the OpenBSC with the Mobicents gateway. However, OpenBSC encapsulates the GSM MAP protocol in a DTAP header, while Mobicents expects a TCAP. The question is: Is possible to use the TCAP protocol in OpenBSC ? PS: Currently I am working with the USSD in OpenBSC. I performed some changes in the code and now we implemented the USSD request,facility and release-complete messages. In other words, now we are able to implement menus in USSD operations. Best Regards

[PATCH] bsc: Add control command to set timezone
by Jacob Erlbeck 02 Oct '13

02 Oct '13

This adds a per BTS control command 'timezone' which expects a value of the format '<hours>,<mins>,<dst>' or 'off' to set the value of bts->tz. It has the same functionality like the existing VTY command 'timezone' in network/bts.
