Evaluating Results

• Severely Errored Seconds
The ratio of the total number of available seconds with an error
ratio worse than 1 x 10
expressed as a percentage.
• Degraded Minutes
Severely errored seconds are discarded from the available time and
the remaining seconds are grouped into blocks of 60 seconds.
Blocks which have an error ratio worse than 1 x 10
Degraded Minutes and Percent (%) Degraded Minutes is the ratio of
the total number of degraded minutes to the total number of 60
second blocks in the available time expressed as a percentage.
Incomplete blocks of less than 60 seconds are treated as complete
blocks of 60 seconds.
• Errored Seconds
The ratio of the errored seconds in the available time to the total
number of seconds in the available time, expressed as a percentage.
