SANTIS ADSL 50/500 User Manual

Status

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. dm t

(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 connet 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.
