Wi-Fi parameters
Remote Vendor ID
The remote vendor ID of the DSLAM that the DSL interface connected to.
Speed
The current speed the downstream and upstream DSL channels in Kbps.
Channel
The channel type being used. It can be either "Fast" or "Interleaved".
Relative Capacity
The current relative capacity on the downstream and upstream DSL channels. The relative
capacity is the percentage of your overall available bandwidth used to obtain your ATM service
rate.
Attenuation
The current attenuation, in decibels, on the downstream and upstream DSL channels.
Attenuation is the measure of how much the signal has degraded between the DSLAM and the
DSL modem. The lower the attenuation, the better the performance will be.
Noise Margin
The current noise margin, in decibels, on the downstream and upstream DSL channels. The
noise margin (aka Signal to Noise Ratio) is the relative strength of the DSL signal to noise. The
larger the noise margin, the better the performance will do. In some instances, interleaving
can help raise the noise margin.
Power Output
The current amount of power, in dBm, that the DSL modem (upstream) and DSLAM
(downstream) are using. The lower the power output, the better the performance will be.
Indicator Bits
The indicator bit values being used on the downstream and upstream DSL channels.
Cells
The number of cells that have received (downstream) and transmitted (upstream).
CRC
The number of CRC errors that have occurred downstream and upstream.
HEC
The number of Header Error Controls (HEC) errors that have occurred downstream and
upstream.
LOS
The number of Loss of Signal (LOS) errors that have occurred downstream and upstream.
SEF
The number of Severely Errored Frame (SEF) errors that have occurred downstream and
upstream.
Corrected Blocks
The number of blocks that have been received and corrected by the forward error correction
(FEC) code.
Uncorrected Blocks
