4.1.4.4 Select Stored Faults (StFaults)

Refer to Table 4-5.
The modem stores the first 10 (Flt0 to Flt9) occurrences of fault status changes in each of
the three major fault categories. Each stored fault status change is also stored with the
time and date of the occurrence. Stored faults may be viewed by entering the StFaults
level from the Select menu.
All stored faults may be cleared by executing the "CLEAR ?? StFaults" command from
the StFaults level.
Stored faults are not maintained through a controller power-on reset cycle. However, the
last known time is maintained in non-volatile RAM. Upon power-up, a common
equipment fault is logged (Flt0) with that time and date. Also on power-up, an additional
common equipment fault is logged (Flt1) to indicate the power-up time and date.
Therefore, on power-up, the power-down and power-up times are logged as common
equipment fault 0 and common equipment fault 1, respectively.
Upon entering the StFaults level, use
and the "CLEAR ?? StFaults" selections.
The time and date of the first stored fault status (Flt0) for the selected group will be
