Line Stats

Your DSL modem continuously monitors the quality of your DSL service. You can obtain line statistical information from your modem to assess the quality of your line and service.

Bell is responsible for the quality of your line and it is worth noting that most of your monthly payment to NCF goes to Bell to provide DSL service on your line.

How to obtain the line stats from your modem

SpeedTouch 585 or 516v6

Line stats displayed on a SpeedTouch 585v6 modem interface (Speedtouch 516v6 is similar)

1. Log into the web interface of your modem (how to log in)
2. In the left column, click on 'Broadband Connection'
3. In the left column, click on 'DSL Connection'
4. In the top-right area, click on 'Details'

Depending on your modem model and configuration, the numbers may be displayed with commas and periods in the European manner, which is the reverse of what is common in North America. For example: 1,000.12 for 'one thousand decimal 12' may be displayed as '1.000,12'.

SpeedTouch 516v5

Your NCF stats

You can see your stats as seen by NCF here. Note the date on that page that says when they were collected.

How to interpret the line stats

____________________________________________________________________________________________________________ | Line Operational Status | (DSL phone number, may or not be your Bell #) | |-----------------------------------------|------------------------------------------------------------| | Line Status: |In Service (preferred state) | UpTime: | (not a useful field, usually not populated by Bell) | | Out of Service (trouble!) | | |

Bandwidth

It is expected for download speed (measured as Mbps or Mb/s) to be faster than upload speed. You can confirm this number by doing a speed test.

Line Attenuation

Attenuation is a measure (in dB) of how far you are from the Bell equipment (DSLAM). Note that Lower is better as it indicates a shorter cable length.

Attenuation	Rating
0 to 40 dB	Excellent
40 to 50 dB	Good
50 to 60 dB	Fair
>60 dB	Poor

Signal-to-Noise Ratio (SNR or SN Margin)

Signal-to-Noise Ratio is a measure of how much electrical noise exists on your line. Too much noise can affect the DSL signal. Higher is better as it means you have more signal than noise.

Signal-to-Noise	Rating
> 20 dB	Excellent
10 to 20 dB	Good
6 to 10 dB	Fair
0 to 6 dB	Poor

Errors

The error figures are an indication of how many packets had to be re-transmitted because they contained an error and may be caused by line noise. Error counts are cumulative since the time DSL sync was last obtained. To reset the error counts, do a software restart of your modem, or power cycle your modem, or disconnect your DSL line for a minute or two.

The significance of error counts is unclear and may be meaningless. Some modems may misreport errors and even with errors, your service may be fine.
