STORED FLTS/ALAMS
The modem stores the first 10 (Flt0 through Flt9) occurrences of fault status changes in
each of the following major fault categories:
• Modulator
• Demodulator
• Transmit Interface
• Receive Interface
• Common Equipment
Each fault status change is stored with the time and date of the occurrence of the fault.
Stored faults may be viewed by entering the stored faults level from the Select menu.
Stored faults are not maintained through controller power-on reset cycle. However, the
last known time is maintained in nonvolatile Random Access Memory (RAM). On
power-up, a common equipment fault is logged (Flt0) with that last known time and date.
In addition, on power-up, an additional common equipment fault is logged (Flt1) to
indicate the power-up time and date. The power-down and power-up times are logged as
common equipment fault 0 and common equipment fault 1, respectively.
On entering the stored faults level, press [
←] or [→] to move between the fault groups
and the “Clear Stored Faults ?” selections. The time and date of the first stored fault
status (Flt0) for the selected group will be displayed alternately on line 2 of the display.
Press [
↑] or [↓] to cycle through the selected group has stored fault status (Flt0 through
Flt9). To display the fault status associated with the displayed time and date, press
[ENTER]. To identify the fault, press [
←] or [→] to move the flashing cursor. To clear
the currently logged stored faults, press [ENTER] when the “Clear Stored Faults/Yes?”
selection is displayed.
Note: Faults are stored in time sequence, with the oldest fault status change stored in
Flt0, and the most recent in Flt9. Only the first 10 fault status changes are stored. All
stored faults, which have not been used, indicate “No Fault” on the display.
