ALARM H [ time ]
The ALARM H command displays alarm events of the past with a time stamp
based on the internal system time of the modem and an offset. The time stamp
has the format day:hour:minute.
The internal system and the time offset are set to zero by each RESET command
or on power-on.
Use ALARM H hh:mm to define a time offset used when calculating timestamps.
The time offset is interpreted as current time.

Note:
• The alarm history is limited to 500 alarm messages per system / DSL link
and a maximum collection time of about 240h
• Once a time offset has been defined with the ALARM H time command, the
offset is stored in the modem. Subsequent ALARM H commands will display
time stamps calculated on basis of the offset previously entered.
• Power-on or RESET resets the internal system time and clears stored events
• The current system time is displayed if the alarm history is empty
CLEAR
The CLEAR command erases all entries of the event log memory as well as the
time adjustment of a previously entered ALARM H command. The internal system
time is not reset by this command.
Events which occur after the CLEAR command will again be displayed with the in-
ternal system time.
