The G.821 counters are now described:
•
ERRORED SEC: shows how many one-second time intervals have at least an error.
•
SEV. ERR. SEC: shows how many one-second time intervals have the bit error rate
equal or higher than 1.10
-3
.
•
DEGRADED MIN: shows how many one-minute time intervals have a bit error rate
higher than 1.10
-6
.
•
AVAILAB.SEC: number of available seconds during the test.
•
UNAVAIL.SEC: shows the number of unavailable seconds during the test.
•
ERR.FREE SEC: shows how many one-second time intervals have no error.
To go back to the ITU-T Standards screen, press <F2> (ITU-T). To display these counters in
percent values, press <F3> (%). A description of each parameter displayed in the percent values
screen follows. They all follow ITU-T Recommendation G.821. To display the FAS, CRC and E-
BIT results, press <F4> (NEXT).
•
ERRORED SEC: indicates the rate between the number of one-second time intervals
that have at least one error and the available measuring time.
•
SEV. ERR. SEC: indicates the rate between the number of one-second time intervals
where the bit error rate is equal or higher than 1.10
-3
and the available measuring time.
•
DEGRADED MIN: indicates the rate between the number of one-minute time intervals
whose error rate is over 1.10
-6
and the available measuring time.
•
AVAILAB. SEC: indicates the rate between the available seconds actually used for
