This Femtocell looks both from a pricing point of view as from a hardware
point of view very interesting. Now that the integration in OpenBSC looks
very promising it would become a good alternative for the more expensive
ip.access picocells. It seems that these HSL femtocell can not be bought
without first investing in the developers pack from HSL which cost as much
as 7000$. Does anyone know how to obtain one of these cells for a
reasonable price? Are they already deployed by operators?
Looking at the internal hardware, it may even become a substitute for the
USRP's....
hello list,
i'd like you to go with me thru my setup of 2 bs11 and verify it. it looks like this:
E1 E1
PC------BTS0------BTS1
let's begin with the bs11_config outputs
bts0:
LMT LOGON: ACK
PHASE: 3 Normal MBCCU0: Load MBCCU1: No Load Abis-link: Restoring
BS11 ATTRIBUTES:
BS-11 ESN PCB Serial Number: 001104

and that's bts1:

BPORT1 GET ATTR NACK <--- do i have to worry about his?
LMT LOGOFF: ACK
here we go with openbsc.cfg. i use only trx0 of each bts. don't ask why i did something like this or like that, i just adapted the openbsc.cfg-file from the packet to my timeslots configured

(0 and 1). Each device corresponds to a port in bs11_config and a line here, right ?

and for the final: the output of bsc_hack during start:

protocol: 4
nrbchan: 14
name: hfc-e1.1-1
activate bchan
activate bchan
DB: Database initialized.
DB: Database prepared.
since line 1 isnt used for bts1 oml, only device id 0 with d-channel on ts 1 is activated. but im quite sure this is a mistake, i need 2 devices for 2 bts. right?
this config dont work at all. bts1 not recognised, bts0 is recognised but cant handle calls. the handys are callable and ring, but no data is transmitted.
please give me as much feedback as possible
mni tnx

hello,
my 2nd bs11 has no load on trx0. may someone give me a bit more detailed
information than on openbsc.org how to create trx0?
tnx in advance

I myself tried this route as I'm a student looking for an inexpensive
way to work with OpenBSC, but...
1: they require a mutual shared NDA before they'll even talk prices;
2: they claim it REQUIRES their proprietary BSC software and thus you
must purchase a femtocell developer kit including their A-bis specs
and a bunch of stuff you don't need, inflating the price; and
3: they only offer their NDA to companies -- individuals and students
need not apply.
4: ... but they DO ship internationally -- GSM1800 only.
But looking at the /only/ price they mention - $7200 US for two
femtocells and all the software -- why bother? You're better off
buying two, maybe three NanoBTS for that price.
And I also seem to question my own point #2 -- they first tell me "If
you do want to use the HSL Femtocell with an alternative to the HSL
BSC..." and then in the latest mail "... our femtocell is designed to
be used with our own BSC" making it seem as if you're not supposed to
be taking it elsewhere.
Le sigh.

Hi all,
I have moved the cellmgr_ng code to GNU AGPLv3 as well. I am going to land
M2UA code, a simple STP tomorrow and also the linkset cleanups I have been doing.
Hi,
Found a perl (!) SIGTRAN stack on the net, thought someone here might be
interested. Includes a very basic HLR emulator and various other bits. Looks
fairly easy to extend to send/respond to various GSM MAP messages, could be
useful for testing.
http://mtve.livejournal.com/13725.htmlhttp://frox25.no-ip.org/~mtve/wiki/SigTranSol.html
Enjoy!
Duncan
Hi all,
the cellmgr_ng code has gained M2UA handling and is on the way that it could
play the classic role of a Media Gateway (MGW) as of RFC3331, or a plain
Signalling Transfer Point.
Is someone interested in helping to finish that up and using it somewhere?
regards
holger
Hi!
The 'preferred' address for the openbsc mailinglist has changed to
openbsc(a)lists.osmocom.org and http://lists.osmocom.org/
However, since the latter is just a virtual instance on the same list server,
the old addresses will continue to work.
Please note, though, the 'List-Id' header will change the doamin name, so you
may have to update your message filter scripts.
Sorry for any inconvenience, but I'm just making sure all the GSM network
related projects are on osmocom.org (like the recent git repository move).
Regards,
Harald

hello
im still trying to make 2 bts work in multidrop mode. bts0, the one on
the pc, tells that:
LMT LOGON: ACK

this bs11 works pretty well as single config.
but bts1 tells that:
LMT LOGON: ACK

BPORT1 GET ATTR NACK
LMT LOGOFF: ACK
as you can see, i configured the 2nd bs11 with ts 17 on port 1,
according the bmask and dmask settings(sorry for that yesterday, but
sometimes there are so many trees you dont see the forest - german
saying), and bsc_hack starts now without problems, but bootstrapping is
only on bts0, bts1 isnt recognised.
when i connect bts1 to the pc and run it in single mode(with line 1
timeslot 17 settings in openbsc.cfg), it is recogised with
bootstrapping, but dont function. it isnt seen by any handy. i put 2
attachments in the mail, hope they arent dropped
could the different pll and work values be the reason?
is the BPORT1 GET ATTR NACK from bts1 a possible reason?
what about the strange messages seen in the bts1_err.jpg?
