D2061 ADSL TESTER
Relative Capacity: Is the relative capacity occupation of ADSL line. This
parameter represents the ratio of the achieved line rate over the attainable line
rate, expressed in percentage. Both line rates are the sum of ATM speed rate
and all the overhead data.

Noise margin: is the realised noise margin of the line.
Attenuation: Is the line attenuation on entire ADSL bandwidth, it‘s the difference
between the reference transmitted signal power and the received power of all
tones.
