T Alarms - Paradyne 3150 Operator's Manual

7. Monitoring and Troubleshooting
Alarms
The CSU can be attached, either locally or remotely, to an ASCII terminal or
printer to display or print alarm messages. Alarms can also be displayed on a PC
that is using a terminal emulation package.
For standalone CSUs, you can route these alarms to the MODEM port, the COM
port, or both. For carrier-mounted CSUs, you can route them to the COM port or
dial them out using an external device.
Each alarm message contains a customer identification to indicate which remote
CSU is reporting an alarm. For information about customer identification, refer to
Displaying Unit Identity
Possible alarm messages are as follows:

If two alarm conditions are detected at once, the higher priority alarm is reported.
However, if an even higher priority alarm is detected before the first alarm is
cleared, the later alarm is not reported. (The alarms listed above are in priority
order with the highest priority listed first.)
Alarms remain active until the alarm condition is cleared. Also, an alarm clear
message is only sent when there are no other alarms active.
