CFIxy Fault Reports
The fault report CFI is followed by the two parameters „xy“ that indicate
the fault type:
CFIAB Dial up or connection interrupted, as no dial tone was
received within 20 secs. or the loop current has failed
for more than 1 second.
CFICB The line is occupied; the modem is not ready for dialing.
CFIFC The modem is constantly blocked (after 12 unsuccessful
dialing attempts). The modem can be reactivated by
disabling the supply voltage and a new POWER ON.
CFINT No answer tone from the remote station within 100 secs.
If necessary this period can be changed by setting
register S7. This process is only possible with the AT
command set.
CFIET Subscriber is busy. A connection cannot be established.
