Channel Element TSI
Mapping Failure #n
This alarm is generated when a BTS detects a problem internally
allocating a SRCHAN to a particular channel element (CE). The
additional data indicates the specific error. The CE is unusable for call
processing.
NOTE
The SC340 device has 16 channel elements, thus it does not detect and
generate alarms 12316–12331.
Span Alarms
18001/
18002
SPAN Degraded –
Remote Fault Daily
Threshold Exceeded
(source)/(sink)
This alarm indicates that the count of remote faults exceeded the alarm
threshold (default threshold = 16) within a 24–hour period. This alarm is
caused by the transmit span line path 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.
18004/
18005
SPAN Degraded –
Remote Fault Hourly
Threshold Exceeded
(source)/(sink)
This alarm indicates that the count of remote alarms exceeded the alarm
threshold (default threshold = 20) within a 1–hour period. This alarm is
caused by the transmit span line path fading in and out. This alarm
condition may have a 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.
18007/
18008
SPAN Degraded –
Remote Fault Critical
Threshold Exceeded
(source)/(sink)
This alarm indicates that the count of remote faults exceeded the alarm
threshold (default threshold = 511) within a 24–hour period. This alarm is
caused by the transmit span line path fading in and out. 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.
