Hi all,
Just wanted to share an issue and a quick workaround I found for it in case
anyone else has the same problem. I believe a cmd2 update is causing
pySim-shell to fail. After installing it on a fresh install of Ubuntu
Server 20.04 and getting the following error when I run "python3
pySim-shell -p0":
>Using PC/SC reader interface
>Autodetected card type: sysmoUSIM-SJS1
>AIDs on card:
> USIM: a0000000871002ffffffff8907090000
>Traceback (most recent call last):

> super().__init__(persistent_history_file='~/.pysim_shell_history',
allow_cli_args=False, use_ipython=True, auto_load_commands=False,
command_sets=basic_commands, >startup_script=script)
>TypeError: __init__() got an unexpected keyword argument 'use_ipython'
If you run into this you can fix it by uninstalling cmd2 and reinstalling
cmd2 with "pip3 install cmd2==1.5".
Best,

I means: is the interaction with mtp3 layer implemented (is sending sccp
data by mtp3 implemented by the library?)?
Also, what about the reception of data from mtp3 layer. is that implemented
in the sccp lib.
I am asking these questions because I see the code of mtp3 in the lib but no
significant call is present in the sccp part of the lib.
Thank you for your help.

A TS can be GSM_PCHAN_TCH_F_PDCH; those are the only ones for which we
send a PDCH ACT message.
We send a PDCH ACT message
- during init (CHANNEL OML's state changed to enabled -> send PDCH ACT),
- and upon channel release ack when pchan == GSM_PCHAN_TCH_F_PDCH.
So the question is, when we receive a channel release ack, could that be
the PDCH release and we switch PDCH right back on by accident? No, because
we only receive a chan rel ack when the *TCH/F* is being released.
That is because the PDCH release is initiated "internally" from the PDCH
DEACT, and thus this condition in common/rsl.c rsl_tx_rf_rel_ack() catches
on, which existed before dyn PDCH:
if (lchan->rel_act_kind != LCHAN_REL_ACT_RSL) {
LOGP(DRSL, LOGL_NOTICE, "%s not sending REL ACK\n",
gsm_lchan_name(lchan));
return 0;
}
In rsl_rx_rf_chan_rel() the rel_act_kind is set to LCHAN_REL_ACT_RSL, but
not in the rsl_rx_dyn_pdch().
This is analogous to the ip.access way -- the ip.access nanobts replies to
a PDCH DEACT with a PDCH DEACT ACK and doesn't send a separate channel
release ack.
Maybe we could set rel_act_kind to some new LCHAN_REL_ACT_IPAC_DYN_PDCH
for clarity? (But we shouldn't actually send a release ack, to stay
compatible.)
Even though it works as-is, we should indeed add another flag check:
- We do check the flags that no ACT/DEACT is already pending;
- And we do send a PDCH DEACT only if ts->flags & TS_F_PDCH_ACTIVE;
- But we would send a PDCH ACT despite ts->flags & TS_F_PDCH_ACTIVE.
This should never happen, but it would make sense to ensure that.

Hi,
My name is Brackley Cassinga Form DRC, we run a community network called
pamoja net where we offer gsm services using osmocom open source software
and OC Base station.
Recently I have tried to install another base station as the same installed
but I could not find any resource guiding through all the steps to take to
run NIB on a base station.
I'm currently running Ubuntu and I will appreciate if you could guide me on
the installation of BSC,hlr,MSC , in order to run a basic gsm network.
Thank you. Regards

Hello Osmocom community,
In my previous reply to Anonymous Internet User msfu666, I mentioned
that I sometimes give out FCSIM1 cards free of cost to certain
recipients, but I did not elaborate on the conditions. I did not
spell out the conditions because I hadn't actually given much thought
to what they should be - but thinking about it now, I realize that
only one condition would actually make sense. My FCSIM1 cards are
good for one and only one purpose: operating your own GSM network
(presumably with Osmocom CNI software, no idea if OpenBTS/YateBTS
would work or not) *for the purpose of* providing service specifically
to vintage handsets. Therefore, the condition becomes quite simple:
if there is anyone here besides just me who operates their own
Osmocom-based GSM network _specifically for the purpose_ of providing
service specifically to _vintage_ GSM handsets and you would like some
of my FCSIM1 cards, please let me know and I'll send you a few.
What are vintage GSM handsets? For the present purpose, we can define
a vintage GSM handset as being one that:
a) has a 2FF SIM socket, as opposed to 3FF or 4FF or eSIM;
b) has a 2G-only radio;
c) does not speak UICC/USIM protocol, only GSM 11.11 SIM.
If anyone besides me operates their own GSM network specifically for
the purpose of providing service to (or just playing with) such vintage
handsets, then FCSIM1 cards would be a good choice for such operation:
hence if you would like some, you can have them for the cost of
shipping. OTOH, if you operate your own network, even if it's a 2G
network radio-wise, for some purpose other than exclusively serving or
playing with vintage handsets, then my FCSIM1 cards will NOT be a good
choice for your applications. Specifically, if you are going to
connect any kind of "modern" phones to your network, even if it's 2G
RAN, those "modern" phones will want 3FF or 4FF SIMs - but my FCSIM1
cards are 2FF only, and thus a poor choice for such usage.

Hello Osmocom CNI folks,
I got my first GSM network up and running, using nanoBTS hardware and
Osmocom CNI sw stack. I compiled everything from source (to my
knowledge, no one makes binary packages for Slackware), but rather
than grabbing the state of git master on some random day, I checked
out tagged versions corresponding to the latest official 2021-11 CNI
release. My configuration is 2G-only, CS-only, minimal split-NITB,
thus the 5 processes I am running are OsmoSTP, OsmoHLR, OsmoMGW,
OsmoMSC and OsmoBSC. I'm using the same OsmoMGW instance for both MSC
and BSC.
The functional state is: phones with FCSIM1 cards in them whose
programming matches the data I entered into HLR are able to connect
(location update succeeds), SMS from one phone to another works, and
USSD requests *#100# and *#101# also work. However, voice calls don't
work. The user-visible symptoms are:
1) When I dial a call from one connected phone to another, the
destination phone starts ringing, and it shows the calling number on
the display - thus CC signaling works correctly at least in the
initial phases.
2) However, a short time (I measured a little under 20 s) after the
start of the process, the destination phone stops ringing and shows a
missed call indication. However, the origin phone continues playing
its NOIBT ringing tone as if it is still waiting for the call to be
answered, and it keeps going for another 15-20 s or so, before it
gives up.
3) Trying to press the answer button on the destination phone before
it stops ringing and goes into the "missed call" state does NOT
produce a connected call state either.
To see what's going on, I turned on maximum verbosity logging in all
OsmoCNI components and plowed through the resulting massive log.
(I am logging via syslog - the whole point of running Slackware is
principled opposition to systemd.) And I see what appears to be the
culprit - see lines 7558 and 7559 in the attached log, UTC timestamp
02:48:54, 11 seconds after I initiated the test call from the origin
phone. It appears that the BTS is telling the BSC that this error
occurred: "Timer T200 expired (N200+1) times", and based on the
lchan(0-0-2-TCH_F-0) annotation, this error is happening on the origin
leg of the call, rather than the destination leg.
I looked up what T200 is:
https://www.rfwireless-world.com/Terminology/GSM-timers.html
T200: "It is used as retransmission on data link layer. Value varies
depending on different messages (for FACCH it is set to 155ms)"
Why in the world are FACCH (or is it SACCH?) data link transmissions
suddenly failing on the origin leg of the call, some 11 to 13 seconds
in? I have tried 4 different phones in the call-origin role (Motorola
C139 running its original fw, Pirelli DP-L10 likewise, Nokia C3-00 and
my own FreeCalypso fw), and the behaviour is always the same.
Has anyone seen this problem before? Is it perhaps a known issue with
nanoBTS that requires some special workaround? This tarball:
https://www.freecalypso.org/members/falcon/osmo-cni/t200-fail-config+log.ta…
contains my configuration files for all 5 OsmoCNI components and an
excerpt from syslog. The syslog excerpt begins with all 5 OsmoCNI
components booting up, followed by two phones connecting, and finally
the test call.
I would really appreciate it if someone could give me some pointers
for debugging this voice call show-stopper.
TIA,
Mychaela
hello,
i ran into an issue with osmo-sim-auth.
if i try ./osmo-sim-auth.py -r 00000000000000000000000000000000 -s
it says

do you know what the problem is? i think i installed pcsc-lite, pcscd
and pyscard and dependencies.
thank you

Hi,
The script seems to be python2 and you are running it with python3.
Either the script has to be ported or yust try to use legacy python2.
