Monitoring Performance

Parameter Description
Possible
Values
LCV
Number of code violations, i.e. – the times
when both a BPV (Bipolar Violation) and an
EXZ error have occurred in one second.
Numerical
LCD
Number of seconds during which Loss of
Cell Delineation was detected.
Note: LCD is not available in E1/T1 CES
mode.
Numerical
RAI
Number of seconds during which Remote
Alarm Indication was detected.
Note: RAI is not available in Unframed
E1/T1 mode.
Numerical
AIS
Number of seconds during which Alarm
Indication Signal was detected.
Numerical
FEBE
Number of Far End Block Error, i.e. –
seconds during which an MF-CRC4 error
indication is received from the remote E1
device.
Note:
FEBE is not available in Unframed
E1/T1 mode.
Numerical
ES
Number of Errored Seconds, i.e. – seconds
during which CRC, SEF (Severely Errored
Frame) or AIS errors have occurred.
Numerical
BES
Number of Burst Errored Seconds, i.e. –
seconds during which 2 to 319 CRC error
events with no AIS or SEF have occurred.
Numerical
SES
Number of Severely Errored Second, i.e. –
seconds during which 320 or more CRC
error events with at least one SEF or AIS
have occurred.
Numerical
DM
Number of Degraded Minutes, i.e. –
minutes during which at least 15 errored
seconds have occurred on a T1 line, or at
least 20 errored seconds on an E1 line.
Numerical
UAS
Number of Unavailable Seconds, i.e. –
seconds counted in the period after 10
consecutive SES occurrences. UAS state is
deactivated after 10 consecutive seconds
without SES occurrences.
Numerical
Rx Frame Slips
Increments when the framer’s buffer is full.
Time elapsed /
Start time
Elapsed time (in seconds) since the
beginning of the current interval.
Start time is for the chosen interval.
0–899
Valid intervals
The number of intervals that are saved
0–24
