hi list,
what impedance should a pair of cable for multidrop have? i used 10m of
cat4, with the result that the 2nd bs-11 wasnt bootstrapped. now i
reduced the length to 3m, and it works. the oszi tells me there are
still some reflections, but finally my 2nd bs-11 is recognised.
so whats the correct cable, when i plan to use more than 3m?

Dear all,
I'm looking forward to buy one or two nanoBTS (165 or 135 whatever available), is there any body who wants to sell his nanoBTS (in Europe) ? ? ?
As i am starting my development on opnebsc, i need it asap :)
looking forward for any offer .
regards,
Please help me out...
After authorization command through hlr,whenever I try sending sms or call
through command line it says
Subscriber not attached.
how to come over it.
Thanks.
hello
my multidrop setup doesnt find my 2nd bs-11 in the chain, although
bootstrapping works, except the strange thing with trx 1, see other
mail. maybe the reason is an error in the cid, lac or bsic settings.
i have:
cell identity 1
location area 1
bsic 63
in the bts 0 section
and
location area 2
bsic 63
in the bts 1 section
evrything ok so far?
the -P parameter makes trouble: altho neccessary for handover, no data
is transmitted when i use it on my 2 bs-11 multidrop config. i can make
calls, the handy rings, but i don't hear anything on any handy. omitting
the -P, i can talk.
is this normal?

Hi!
The following patches split libosmocore in two libraries, the new
libosmo-gsm, which contains GSM-specific functions, and libosmocore,
which contains generic functions (like talloc, msgb, select, logging, ...).
In case that you're OK with them, you have to apply them in the
following way:
1) First, make a copy of libosmocore.git to libosmo-gsm.git. This is
done to avoid losing the history in the new libosmo-gsm.git library.
$ cp -r libosmocore.git libosmo-gsm.git
2) Apply the patch that removes the GSM-specific features to
libosmocore.git (see [PATCH 1/2])
2) Apply the patch that removes the non-GSM features to libosmo-gsm.git
(see [PATCH 2/2])
After these patches, I'll send two patches for openbsc and osmocore-bb
to make them use the new libosmo-gsm.
Let me know what you think with this proposal.
hello list
please the the entire mail thoroughly before answering.
it's a neverending story with the bs-11 f***ing multidrop: i have bts0 that works perfect as single, and so does bts1, but only bts0 is bootstrapped
lets start from the beginning: misdn is configured port 0 has ts1 as d-channel and 2-15 as b-channels, port 1 has ts17 as d-channel and 18-31
as b-channels.
that says bs11_config for bts0, that is connected to pc:
SITE MANAGER ATTRIBUTES:
E1 Channel: Port=0 Timeslot=1 (Full Slot)
TEI: 25
BS11 Line Interface ATTRIBUTES:
PLL Mode: Standalone
BS11 CCLK ATTRIBUTES:
CCLK Accuracy: High (1)
CCLK Type=0
BS11 Power Amplifier 0 ATTRIBUTES:
TRX Power: 30mW (GSM)
BPORT0 ATTRIBUTES:
Line Configuration: Multi-Drop (1)
BPORT1 ATTRIBUTES:
Line Configuration: Multi-Drop (1)
and that is bts1:
SITE MANAGER ATTRIBUTES:
E1 Channel: Port=1 Timeslot=17 (Full Slot)
TEI: 26
BS11 Line Interface ATTRIBUTES:
PLL Mode: Standalone
BS11 CCLK ATTRIBUTES:
CCLK Accuracy: High (1)
CCLK Type=0
BS11 Power Amplifier 0 ATTRIBUTES:
TRX Power: 30mW (GSM)
BPORT0 ATTRIBUTES:
Line Configuration: Star (0)
BPORT1 GET ATTR NACK
LMT LOGOFF: ACK
as you can see, the d-channels match with the bts-setting. each bs-11 have a working trx0 and a high clock accuracy.

both bs-11 works as single with the corresponding section (bts 0 or 1) of the cfg file. i have differents teis for all lapd connection.
i use cat4 cable for the bs-11 connection (10 m between the bs-11s)
maybe the screenshot attached unveils the problem.
any help/hint is very welcome.
