•
ES RATE: indicates the rate between the value of the errored seconds (ES) given by the
ERRORED SEC counter and the available measuring time.
•
SES RATE: indicates the rate between the number of severely errored seconds (SES),
given by the SEV.ERR.SEC. counter and the available measuring time.
•
BBE RATE: indicates the rate between the number of background block error (BBE)
received and the total number of received blocks during the available time, without SES.
•
AVAILAB.SEC: indicates the number of available seconds during the test.
•
UNAVAIL.SEC: indicates the number of unavailable seconds during the test.
To go back to the ITU-T Standards screen press <F2> (ITU-T). To go to the first G.826
screen press <F1> (BACK). These counters are updated each second. However, these data are
recalculated if unavailable seconds occur (going back 10 seconds).
The TSW200E1 calculates parameters according to ITU-T Rec. M.2100. These parameters
are shown in the following two screens.

•
ERRORED SEC (ES): shows how many one-second time intervals have at least one of
the following errors: FAS or EB or LOS (signal loss) or AIS or LOF (FAS loss).
•
SEV.ERR. SEC.: for PCM30 and PCM31, displays the number of one-second time
intervals where more than 805 Errored Blocks (Ebs) occurred or more than 28 FAS
errors (PCM30 and PCM31) occurred. Or if any of the alarms LOS, AIS or LOF
occurred.
