Severity Description
Critical An alarm condition has been detected on the
specified T1 line, or the signal on the T1 line has
been lost.
Critical An alarm condition has been detected on the
specified T3 line, or the signal on the T3 line has
been lost.
The HSSI port has failed to initialize.
Major The Ethernet port has failed to initialize.
Major The cooling fans have stopped.
Major The external power source has dropped.
Major The primary SCC has failed, and the secondary SCC
has resumed operation. CVXView generates this
alarm. Although the raising trap is generated on the
CVX 600, it does not recognize this as an alarm
condition. This alarm must be cleared manually on
CVXView (Clear Alarms button).
Minor The sending protocol entity recognizes a failure in
one of the communication links represented in the
agent's configuration.
Minor Communication has been lost between the indicated
slot and the SCC.
Major Transitions are not detected on incoming signals,
therefore, a loss of signal is declared.
Major An OOF/SEF defect has persisted for a period of 3
milliseconds, therefore, a loss of frame is declared.
Minor The C2 field value in the received frame does not
match the configured value in the SigLabelExpect
attribute.
Minor The specified STM-1 is in S1 New Alarm. The S1
field in the received frame contains a new value.
