Below are some of the
common terms and measurements used to judge line quality.
Remember these are not hard numbers but simply a generalization of
line statistics:
Line Attenuation
Measure of how much the signal has degraded between the DSLAM and the
modem. Maximum signal loss recommendation is usually about 60dB. One
of the biggest factors affecting line attenuation is distance from
the DSLAM. Generally speaking, bigger distances mean higher
attenuation. The lower the dB the better for this measurement.
 20dB and below is outstanding
20dB-30dB is excellent
30dB-40dB is very good
40dB-50dB is good
50dB-60dB is poor and may experience
connectivity issues
60dB or above is bad and will experience
connectivity issues |
SN Margin
(AKA Signal to Noise Margin or Signal to Noise Ratio)
Relative strength of the DSL signal to Noise ratio. 6dB is generally
the lowest dB manufactures specify in order for the modem to be able
to synch.
In some instances interleaving can help raise the noise margin to an
acceptable level. Generally speaking, as overall bandwidth increases,
your signal to noise ratio decreases. So a customer that upgrades from
1.5 to 6.0 service will typically see a corresponding decrease in the
signal to noise ratio. The higher the number the better for this
measurement.
6dB or below is bad and will experience
no synch or intermittent synch problems
7dB-10dB is fair but does not leave
much room for variances in conditions
11dB-20dB is good with no synch
problems
20dB-28dB is excellent
29dB or above is outstanding |
