  • Page 20 If during transit more than a certain amount of data has been lost then the data cannot be correctly decoded. Short bursts of noise on the line can cause these data packets to become corrupt and NV-520G has to re-request data which in turn can slow down the overall rate at which data is transmitted.

By increasing the interleave depth of each port that are susceptible to noise, this will improve error performance and stability of marginal lines. INP(Impulse Noise Protection): Impulse noise in multicarrier communication systems behaves effectively as a modulating signal that controls the first moment of the background Gaussian noise.
