What are adsl line stats?
SNR (Downstream) & Line Attentuation(Downstream)
Line stats are a set of various figures that can give some indication about the status and condition of your adsl connection.
When using your linestats as a diagnostic tool you have to look at all the figures and not just rely on say just the sync speed or SNR Margin.
When looking at your linestats, you generally need to look at the downstream figures.
~ How do I get my line stats?
Most adsl modems or routers will provide you with your dsl line stats.
I maintain a list of instructions for the most commonly used adsl modems and routers, which will help you find the figures you need.
- SeeHow to get adsl line stats from your router. Your ISP will also be able to get your line stats by performing something called aWOOSH test which will advise them your loop loss (attenuation) and SNR Margin. However, due to the time element involved, most ISPs are very reluctant to perform this test unless it is specifically in relation to an adsl fault. A BT Openreach adsl faults engineer will also be able to access your line stats by hooking up his equipment to your line.
~ Which figures do I need to look for?
Various makes of routers may name the figures slightly differently, but the important figures that you are looking for should be something similar to:
Connectionor Sync Speedor Rate
Attenuationor Attenor Loop Loss
SNR Marginor Noise Marginor Noiseor Margin
Details of any CRC/HEC/RS/FEC errorsand Errored Seconds may also be helpful.
