SIM Card is Out of Order

The hardware for the SIM interface from MAD2WD1 (D300) to the SIM connector (X100)
can be tested without a SIM card.
When the power is switched on and if the BSI line (X102;1) is grounded by a resistor, all
of the used lines (VSIM, RST, CLK, DATA) rise up to 5V four times. Thus, "Insert SIM card"
faults can be found without a SIM card.
The fault information "Card rejected" means that the ATR message (the first message is
always sent from card to phone) is sent from the card to the phone, but the message is
somehow corrupted, data signal levels are wrong, etc., or factory set values stored to the
EEPROM are not correct.
