Hi,
thanks for the answer!
This femto seems to have a discrete simcard (it has empty slot accessible from the external).
I don't know the setup used by the original operator (TelecomItalia), because I bought it from ebay.
I found a possible reset procedure (still to be tested), but I don't think it will "unlock" the board.
Now
I'm trying to find the UART on the board, but on the testpoints i only
see "control" signals and clocks. Nothing seems to be a serial port
pattern on my oscilloscope.
No one tried to disassemble it or do have just the serial pinout on the board?
On
the other side I've already deployed the CN part (HLR + MSC + SSGN +
GSGN + STP + MGW + HNBGW), which seems to be fully operational, but i
can't test without a test cell.
I also thing the IuH protocol
of this femto is little out-of-standard, but from ALU documentation I
can't understand the differences with standard IuH.
The
idea is to implement ALU's IuH variant on HNBGW if i can take traces
from a "lab" env, but without the femto it's just impossible.
