DESCRIPTION
This field displays the name of the CPE VDSL device serial number.
This is the number of far end cyclic redundancy checks.
This is the number of near end cyclic redundancy checks.
This is the number of far end corrected blocks.
The is the number of near end corrected blocks.
This is the number of Errored Seconds. This is how many seconds contained at
least one errored block or at least one defect.
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.
This is the number of Unavailable seconds (Uas).
This is the number of Loss Of Frame (Lof) seconds.
This is the number of Loss Of Signal (Los) seconds.
This is the number of times a Loss of PoweR (on the ATUR) has occurred.
This is the number of Cyclic Redundancy Check (CRC) error seconds.
This is the number of Lost Sync Word (LOSW) seconds.
This is the number of segment anomaly seconds.
This is the number of segment defect seconds.
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.
sending data.
These are the highest theoretically possible transfer rates (in Kbps) at which the
port could receive and send data.
These are the DSL line's noise margins. Measured in decibels (dB).
These are the reductions in amplitude of the DSL signals. Measured in decibels
(dB).
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.
