Ses (seconds) This is the number of Severely Errored Seconds. This is how many seconds contained
30% or more errored blocks or at least one defect. This is a subset of Es.
Uas (seconds) This is the number of Unavailable seconds (Uas).
Lofs (seconds) This is the number of Loss Of Frame (Lof) seconds.
Loss (seconds) This is the number of Loss Of Signal (Los) seconds.
Lprs (seconds) This is the number of times a Loss of PoweR (on the ATUR) has occurred.
CRC This is the number of Cyclic Redundancy Check (CRC) error seconds.
Losws This is the number of Lost Sync Word (LOSW) seconds.
Segment Anomaly This is the number of segment anomaly seconds.
Segment Defect This is the number of segment defect seconds.
Payload Rate
(Kbps)
These are the data (the payload data without transport layer protocol headers and traffic)
transfer rates (in Kbps) at which the port is receiving and sending data.
Actual Rate (Kbps) These are the data transfer rates (in Kbps) at which the port is receiving and sending
data.
Attainable Rate
(Kbps)
These are the highest theoretically possible transfer rates (in Kbps) at which the port
could receive and send data.
Noise Margin (dB) These are the DSL line’s noise margins. Measured in decibels (dB).
Attenuation (dB) These are the reductions in amplitude of the DSL signals. Measured in decibels (dB).
US0~US3,
DS1~DS3
These columns displays the following line status for upstream bands 0, 1, 2, 3, 4 (US0,
US1, US2, US3) and downstream bands 1, 2, 3, 4 (DS1, DS2, DS3).
SNRM (dB)
This field displays signal-to-noise ratio margin in each band. NA displays when the band
is not used.
LATN (dB)
This field displays the line attenuation situation in each band. NA displays when the band
is not used.
SATN (dB)
This field displays the signal attenuation situation in each band. NA displays when the
band is not used.
TXPW (dBm)
This field displays the transmission power in each band. NA displays when the band is not
used.
Poll Interval(s) The text box displays how often (in seconds) this screen refreshes. You may change the
refresh interval by typing a new number in the text box and then clicking Set Interval.
Stop Click Stop to stop port statistic polling.
