SPAN Out–of–Service
– Continuous RED
Faults (source)/(sink)
This alarm indicates that the span is out–of–service due to continuous
RED faults being received for more than 2.5 seconds. A RED Alarm
Event is generated when there is a Loss of Signal, Loss of Frame
Alignment or the Bit Error Rate >= 10E–3. This alarm indicates that the
receive span signal was lost, the receive framing words were corrupted, or
an incompatible remote span interface was detected by the network. This
alarm will be sent by one of the two devices at the end of the span.
In some cases, a second alarm will be sent by the device at the other end
of the span. One alarm will have “(source)” to indicate that it came
from the source end point, and the other will have “(sink)” to indicate
that it came from the sink end point.
18070/
18071
SPAN Degraded –
Sync Loss Daily
Threshold Exceeded
(source)/(sink)
The alarm indicates that the count of synch loss alarms has exceeded the
alarm threshold (default threshold = 16) within a 24 hour period. This
alarm condition will have an insignificant impact on system performance
and call quality. This alarm may provide an early warning of a more
serious condition. This alarm will be sent by one of the two devices at the
end of the span.
In some cases, a second alarm will be sent by the device at the other end
of the span. One alarm will have “(source)” to indicate that it came
from the source end point, and the other will have “(sink)” to indicate
that it came from the sink end point.
18073/
18074
SPAN Degraded –
Sync Loss Hourly
Threshold Exceeded
(source)/(sink)
The alarm indicates that the count of synch loss alarms has exceeded the
alarm threshold (default threshold = 20) within a 1 hour period. This
alarm condition may have an minor impact on system performance and
call quality. This alarm may provide an early warning of a more serious
condition. This alarm will be sent by one of the two devices at the end of
the span.
In some cases, a second alarm will be sent by the device at the other end
of the span. One alarm will have “(source)” to indicate that it came
from the source end point, and the other will have “(sink)” to indicate
that it came from the sink end point.
18076/
18077
SPAN Degraded –
Sync Loss Critical
Threshold Exceeded
(source)/(sink)
The alarm indicates that the count of synch loss alarms has exceeded the
alarm threshold (default threshold = 511) within a 24 hour period. This
alarm indicates that system performance and call quality is seriously
degraded. This alarm will be sent by one of the two devices at the end of
the span.
In some cases, a second alarm will be sent by the device at the other end
of the span. One alarm will have “(source)” to indicate that it came
from the source end point, and the other will have “(sink)” to indicate
that it came from the sink end point.
