Status
DSL Connection
This page shows the DSL line connection status as below:
Line Mode: The ADSL Router supports multi-mode standard: ANSI T1.413, G.lite (ITU-T G.992.2) and
G.dmt (ITU-T G.922.1).
DS (Downstream)/
US (Upstream) Speed: The downstream/upstream speed of the DSL line.
DS/US Latency: Displays whether a fast or interleaved latency path is specified.
Trellis coding: Indicates trellis coding is enabled or disabled. Trellis coding is a method of providing better
performance in a noisy environment. It helps to transmit at faster line rates with lower error
rates, thus providing a faster overall throughput in a moderately noisy environment.
Line Attenuation: Indicates the signal attenuation caused by line length. It increases with line length and
frequency and decreases as wire diameter increases.
Noise Margin: Signal to noise ratio. The ratio of good data (signal) to bad (noise) on the line, expressed in
decibels (dB).
Loss of Signal /Frame: Indicates the loss of signals or frames detected.
CRC Error: Cyclic Redundancy Checksum generated.
Line Up Count: The number of times that you connect to.
Line Up Time: The duration time of the line connecting.
Error Second: The accumulated seconds of the seconds during which packet error message occur.
System Up Time: The time from system startup.
