ES
The Errored Seconds (ES) field shows the total number of seconds in which any errors were
detected. Since this is an information-only field, there are no user-selectable parameters.
SES
The Severely Errored Seconds (SES) field shows the total number of seconds in which the bit
error rate exceeded one bit per thousand (1 x 10-
3
). Since this is an information-only field,
there are no user-selectable parameters.
CSES
The Consecutive Severely Errored Seconds (CSES) field is triggered by the occurrence of ten
consecutive Severely Errored Seconds. Once triggered, the CSES field will increment (by
one) for each elapsed second until the system logs ten consecutive non-Severely Errored
Seconds. Since this it an information-only field, there are no user-selectable parameters.
OSS
The Out of Synchronization Seconds (OSS) field shows the number of seconds that the BRI
BERT has been out of synchronization. Since this is an information-only field, there are no
user-selectable parameters.
BER
The Bit Error Rate (BER) field shows the rate at which errors are being logged. The system
calculates BER by dividing the number of bit errors (BE) by the total number of bits
transmitted during the test. Since this is an information-only field, there are no user-selectable
parameters.
ELA
The Elapsed time field shows the running tally of the total number of seconds during the test.
Since this is an information-only field, there are no user-selectable parameters.
L1-ST
The U Interface State field shows the actual status of the active ports at all times. Entries for
this field include stdby (standby), init (initializing U interface activation), actv (U interface
is active), fail (failed to activate U interface), deact (deactivated), nos (no signal), los (loss of
