When individually enabled, a specific alarm is sent at the start of the
corresponding alarm condition. If multiple alarm conditions are detected at the
same time, only the highest priority alarm will be sent. Any other alarms (even
those of higher priority) are sent out only after the displayed alarm clears. When
an alarm clears, the highest priority alarm still remaining (if any) is displayed.
Once the last alarm condition is cleared, an alarm cleared message is sent.
ASCII Alarm messages are dialed out via an external device (e.g. modem)
connected to the Management port. This can only occur when, in addition to the
above, the following conditions are true:
Phone directories are setup. Refer to
Call Setup
in Chapter 3.
External Device Commands is set to AT or Other. Refer to
External Device
Options
, Table A-7.
Alarm and Trap Dial-Out is enabled. Refer to
Alarms & Traps Options
,
Table A-9.
ASCII Alarm Messages
Refer to the
Entering Device and System Information
section of Chapter 3 for
device name information. Each ASCII alarm message is preceded by the device
name and a time stamp. The time stamp
(ddd:hh:mm) represents the cumulative
number of days, hours, and minutes since the DSU/CSU’s last reset. The time
resets to zero on power up, reset, or after 451 days. An ASCII alarm message
displays similar to this example:
NE815378
283:14:57
Continuous Loss of Signal detected
at the Network Interface
The following messages can be generated by the DSU/CSU and are listed in high
to low priority order:
Continuous Loss of Signal detected at the Network Interface.
Continuous Out of Frame condition detected at the Network Interface.
Alarm Indication Signal received at the Network Interface.
An Excessive Error Rate has been detected at the Network Interface.
Yellow alarm signal received at the Network Interface.
