Alarms - Paradyne 3150 Operator's Manual

ACCULINK 315x CSU

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 the
Displaying Unit Identity section in Chapter 3, Operation.
Possible alarm messages are as follows:
Continuous Loss Of Signal detected at the x
Interface (where x is either Network or DTE).
Alarm Cleared. Loss Of Signal condition at the x
Interface (where x is either Network or DTE).
Continuous Out Of Frame condition detected at
the x Interface (where x is either Network or
DTE).
Alarm Cleared. Out Of Frame condition at the x
Interface (where x is either Network or DTE).
Alarm Indication Signal received at the x
Interface (where x is either Network or DTE).
Alarm Cleared. Alarm Indication Signal at the x
Interface (where x is either Network or DTE).
An Excessive Error Rate has been detected at
the Network Interface.
Alarm Cleared. An Excessive Error Rate at the

(where x is either Network or DTE).
Alarm Cleared. Yellow Alarm signal at the x
Interface (where x is either Network or DTE).
4-8
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.
For information about alarm configuration options,
refer to the Alarm Configuration Options
Appendix C, Configuration Options.
For troubleshooting information, refer to the
Troubleshooting section on page 4-10.
