TIP(Reference Only):
Interleave delay function is used in digital data transmission technology to protect the transmission against noise issue
and data error.
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 the bridge has to re-request data which in turn
can slow down the overall rate at which data is transmitted.
Interleaving is a method of taking data packets, chopping them up into smaller bits and then rearranging them so that
once contiguous data is now spaced further apart into a non continuous stream. Data packets are re-assembled by your
bridge.
The diagram below is an example of how interleaved traffic is transmitted.
If your line is particularly susceptible to bursts of noise then interleaving should improve your VDSL2 experience simply
because if you lose a whole batch of data then this could cause your bridge to loose sync with the exchange.
Using Interleaving, the bridge is able to re-assemble the data or if necessary just re-request the part of the data that it is
unable to recover. By increasing the interleave depth of each ports that are susceptible to noise, this will improve error
performance and stability of marginal lines.
