hi list,
have to sync one of my bs-11. got the hfc-s card and soldered the 2
wires.
is any driver needed for the hfc-s?
or is the clock always on c4io and f0io once the card is plugged in?
the hfcmulti driver loads the e1 card, i have a bmask and a dmask
parameter in modprobe.conf. should i remove them or just hang on the
"type=0x00800"?
i have only one try, so i want to clear all possible problems before
T.

Hi,
Can You please help me how to setup a session - packet or CS call session and capture trace messages - protocol traces , Alarms, Performance Management Counters and CDR?
It will be very kind of you if you help me in this issue.

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

BPORT1 ATTRIBUTES:

LMT LOGOFF: ACK
and that's bts1:
LMT LOGON: ACK
PHASE: 3 Normal MBCCU0: Load MBCCU1: No Load Abis-link: Restoring
BS11 ATTRIBUTES:
BS-11 ESN PCB Serial Number: 001112
BS-11 ESN Hardware Code Number: 135-2044/03.03
BS-11 ESN Firmware Code Number: 135-2044/03.03

SITE MANAGER ATTRIBUTES:
E1 Channel: Port=1 Timeslot=17 (Full Slot)

CCLK Type=0
BS11 Power Amplifier 0 ATTRIBUTES:

BPORT0 ATTRIBUTES:
Line Configuration: Star (0)
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 ?
oml e1 tei 25 <-- here again: all oml e1 teis identical?

rsl e1 line 0 timeslot 17 sub-slot full

and for the final: the output of bsc_hack during start:
2 devices found

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
