SPAN Out–of–Service
– Continuous REC
Faults (source)/(sink)
This alarm indicates that the span is out–of–service due to continuous
Receive Error Condition (REC) faults being received for more than 2.5
seconds. 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.

SPAN Degraded –
RED Fault Daily
Threshold Exceeded
(source)/(sink)
This alarm indicates that the number of RED faults exceeded the alarm
threshold (default threshold = 16) within a 24–hour period. 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 is caused by the
receive span fading in and out. 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.

18062
SPAN Degraded –
RED Fault Hourly
Threshold Exceeded
(source)/(sink)
This alarm indicates that the number of RED alarms exceeded the alarm
threshold (default threshold = 20) within a 1–hour period. 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 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.
18064/
18065
SPAN Degraded –
RED Fault Critical
Threshold Exceeded
(source)/(sink)
This alarm indicates that the number of RED alarms exceeded the alarm
threshold (default threshold = 511) within a 24–hour period. 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
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.
