Service Disruption Time (SDT)
No Defect Time
: Available for
Defect Mode
only.
No Defect Time
represents the period without any defects before stopping SDT
measurement. Choices are from
20
to
99990
μ
s
for
10/100/1000Mbps
and
10
to
99000
μ
s
for
10Gbps
. The maximum value is adjusted with
respect to the test period (the max
No Defect Time
is obtained when
the
Test Period
value is set to its maximum value: 300000000
μ
s). The
default setting is
20
μ
s
for
10/100/1000Mbps
and
10
μ
s
for
10Gbps
.
Unit measurement selections are

Test Period
: Represents the period of time used to calculate the SDT
measurement. Choices are
20
μ
s
to
5 minutes
for
10/100/1000Mbps
and
10000
μ
s
to

On/Off
button: Press On/Off to enable/disable the disruption time
measurements. However, the measurement will only start if the test is
already started, or when the test will be started.
Note:
Stopping the SDT test will stop the measurement without clearing the
results. The SDT test is automatically stopped without clearing results when
the test is stopped. However, starting the test again while the STD is still On
(enabled) will reset the results before restarting.
