ARP T
ABLE
SNR Margin Downstream/Upstream (db) — Displays the current
◆
signal-to-noise margin expressed in decibels (dB). SNR is the ratio of
signal power to the noise power corrupting the signal.
◆ Vendor ID – The vendor name of the digital signal processor (DSP).
DSP Version – The current hardware version of the digital signal
◆
processor (DSP).
CRC Errors — Displays the CRC (cyclic redunancy check) - a type of
◆
function that takes as input a data stream of any length, and produces
as output a value of a certain space, commonly a 32-bit integer.
Upstream/Downstream BER – The the rate at which bits in the data
◆
stream that have been altered by noise.
Up/Down Output Power — Displays the upstream/downstream
◆
power level employed for ADSL port filtering.
ES — Displays the total error seconds, the number of second intervals
◆
during which there was one or more CRC anomalies, or one or more
Loss of Signal (LOS) or Loss of Framing (LOF) defects.
SES — Displays the total severly errored seconds. The number of
◆
second intervals containing 18 or more CRC-8 anomalies, one or more
Loss of Signal (LOS) defects, one or more Severely Errored Frame
(SEF) defects, or one or more Loss of Power (LPR) defects.
◆ UAS — Displays the total unavailable errored seconds, the number of
seconds during which the ADSL transceiver is powered up but not
available.
ADSL Retrain — Retrains the DSL line.
◆
The ARP page displays IP address to MAC address mapping entries
determined by the Address Resolution Protocol.
