I’ve been struggling with my CompTIA exam prep and honestly, it's been hard to manage everything. The idea of asking someone to take my online CompTIA exam for me https://www.theresearchguardian.com/take-my-comptia-exam-for-me/ seemed a bit extreme at first, but after seeing how many students do it, I’m starting to consider it seriously. If anyone has tried this service, I’d love to hear your thoughts. Was it worth the investment? How reliable were the test takers? I just want to make sure I'm making the right choice.
Dear list,
At the moment setting up the RSL lapd link and start its bootstrap
(BCCH info and SACCH filling) is done in one go (as much as I can
see).
The issue with this is for the Nokia Site family: per spec. we should
let the RSL lapd link to be initiated by the BTS and once that lapd
link is up, the BTS sends a BTS_STATE_CHANGED message with "TRX,
enabled" object id and object current state, and only after this we
should start sending the BCCH info and SACCH filling (the "actual"
bootstrap of the RSL).
For this to work, we need the Object Identity and Object Current State
attributes (which is a WIP atm), but somehow it should be possible to
separate the RSL bootstrap to RSL lapd only and RSL bcch info + sacch
filling.
I am unaware if the above separation is possible with the current
codebase, but if someone can shed some light on this, that would be
appreciated.
Adding the Object Identity and Object Current State will also allow us
to detect the actual state changes of various BTS objects (mostly the
TRX), and we can also use the BTS_CHA_ADM_STATE to actually
lock/unlock TRXes, so we dont need to fake the 12.21 state anymore.

Hello Osmocom community,
Over the past several months I developed my own RTP endpoint
implementation library (alternative to libortp), and I seek to get it
merged into libosmo-netif so it can be used by OsmoBTS as an option:
https://gerrit.osmocom.org/c/libosmo-netif/+/39280https://gerrit.osmocom.org/c/libosmo-netif/+/39281https://gerrit.osmocom.org/c/libosmo-netif/+/39291
I am now working on documentation, which I need to finish before I can
lift these patches out of WIP in Gerrit. The last of the 3 WIP patches
linked above is the one adding an adoc manual, built with the same
tools as other Osmocom manuals, and I need some help with this one:
1) When I run './configure --enable-manuals' followed by 'make' on the
Debian machine which Vadim provided to me for Osmocom documentation
work, everything seems successful and I get a PDF rendering of my WIP
manual. However, as soon as I uploaded this patch to Gerrit, I see a
build failure in Jenkins. What am I doing wrong? I'm afraid that my
knowledge of Autotools is not good enough to figure this one out.
2) My progress in writing the actual manual has reached the point
where I need to insert some graphical diagrams showing the flow of RTP
packets and the latency and jitter they experience in transit. I am
thinking of one horizontal axis showing regularly spaced packets as
they are emitted by the source, then forward-and-down arrows showing
their transit with fixed or variable latency, then another horizontal
axis below showing the receiver's view of time, with marked arrival
times of packets (endpoints of latency arrows) and fixed-spacing times
when the GSM or TDM system polls the jitter buffer.
Question: what is the appropriate tool within the accepted Osmocom
adoc suite for drawing such diagrams? If I weren't trying to get my
RTP implementation accepted into Osmocom, I would have written this
manual in troff on my favorite 1980s UNIX system, using pic preprocessor
in the troff suite for graphical drawings like this one - but I reason
that I need to write my manual within Osmocom documentation framework
in order to maximize the chance of the associated code library being
accepted into libosmo-netif, with follow-on patches to osmo-bts to use
it optionally as an alternative to libortp.
3) When I do successful test builds on Vadim's Debian machine and get
a PDF rendering of my WIP manual, the cover page in the PDF features
both Sysmocom and Osmocom logos just like the mainstream Osmocom
manuals, with Sysmocom logo on top. While this arrangement is probably
appropriate for the existing manuals which were written predominantly
by members of Sysmocom crew, it seems quite wrong for an external
contributor's manual that does not contain a single sentence written
by Sysmocom. How do I tweak things to remove that Sysmocom logo from
the cover page, or even better, put San Diego 2G Association logo in
its place? My contributions to Osmocom are directly linked to my
efforts to build a new GSM network in San Diego, hence there is some
symmetry between Sysmocom and SD2G in terms of Osmocom FLOSS project
contributions, except for the rather big asymmetry in that SD2G is
strictly non-profit.

Hi!
I am in possession of a pair of Siemens BS11 mounting plates and am
looking for a second pair. A photo of the plates is attached.
Since - I believe - most people who play with such basestations do not
mount them to a wall or pole, my hope is that some unused ones are
floating around somewhere.
Thanks,
-Alex^Wblackbit
