Not long! The profile change is set through to TalkTalk Wholesale as soon as you click the button on the control page, and the line will resync within a minute. If the profile change failed, then the log will say failed, it it was successful then it will say Done:

**Note: Some fixed profiles omit the SNR property from their name, where this is the case their target margin is 6dB6 dB.

SNR is a measure of signal strength and as such is measured in Decibels (dB). The values in use on the TTTTTW network are:

Packets of data that are transferred across a DSL line are split down into smaller blocks of data; these are then sent sequentially sent across the DSL line. As they arrive at the receiving end, they reconstructedare backrecombined into the original larger packets of data.

If one block of a larger packet is lost due to line interference, the packet can be recreated using the remaining blocks that were received; data blocks reserve some space for data which can salvage a partially damaged block. This is known as Error''error Correctioncorrection''. Interleaving can be used as a form more robust form of error correction.

The ‘Delay’‘delay’ of the Interleavinginterleaving is simply a measurement of the size of the interleaving buffers. The size is measured in milliseconds (ms).
