NSW-6
Disassembly & Troubleshooting
The phone doesn't register to the network or phone
doesn't make a call
If the phone doesn't register to the network or the phone doesn't make a
call, the reason could be either the baseband or the RF part. The phone
can be set to wanted mode by WinTesla service software and determinate
if the fault is in RF or in baseband part (RF interface measurements).
The control lines for RF part are supplied both the System Asic (MAD
D202) and the RFI (Cobba N250). MAD handles digital control lines and
Cobba handles analog control lines.
