This looks completely broken (misparsed by bs11_config?)
It is okay, I see similiar message with my BS-11.
Another issue are the Set- and Work-values of the
Phase-Locked-Loop:
We synchronized it with the ISDN network (isdnsync) and it leveled
off to
1104 for the Work-Value, Set-Value, however, is 1082. I suspect this
is
ok and set-value is some informational value only (perhaps the value
of the last calibration?).
What type of E1 adapter do you use? If you use an accurate clock source,
Work and Set values should be similiar (I have Set Value 1024, Work
value 1023,
and I've used Nateks E1 SDH Mux with High-Stability Stratum oscillator
when
calibrating). See

One more question about the radio carrier: On startup
of bsc_hack we
get
the following message:
OC=RADIO CARRIER(02) INST=(00,01,ff) STATE CHG: OP_STATE=Disabled
AVAIL=In test(00)
Is this normal behaviour?
Of course, no. This means that you have no carrier turned on. It is
very helpful to
use spectrum analyzer in order to ensure that you have correct carrier
with correct
frequency according to the selected ARFCN.
Apart from all this questions, does anyone have some
more hints what
we
should look at? We tried different cell phones, tried switching them
off
and on, but without any success.
We're using the latest git version of openbsc.
What version of Linux kernel and mISDN do you use? I had some problems
with
built-in mISDN also, and get all the stuff working after downloading
and installing latest mISDN
stack from
misdn.org
