Loop Attenuation (dB)
Measured loop attenuation in dB; longer loop length results in high loop attenuation.
SNR (dB)
The SNR (“signal noise ratio”) is an index of the line quality. The larger the SNR the better is
the line quality. The SNR ranges from -10 dB to 21 dB.
3.4.3
Performance
This view shows actual performance values of all lines.
Time Stamp
Shows the time after activation of the NT function or the elapsed time (24h format) after acti-
vation of the SHDSL line.
TMP (total measurement period)
Full duration (time interval) of counting performance data; will be reset after 15 minutes =
900 seconds
ES (errored seconds)
number of seconds with errors
SES (severe errored seconds)
number of seconds with major alarms
CRC6 (cyclic redundancy check)
number of CRC6 errors
LOSW (los of sync word)
number of LOSW errors
UAS (unavailable seconds)
number of seconds without data transmission
3.4.4
Performance History
For line selection please click at line number above the table. The performance history shows
all errors which occurred in the 15-minute intervals over one day (24 hours).
