Interleaving involves the use of powerful error-correction algorithms to improve broadband speed and stability on long or noisy phone lines.
While interleaving helps make your broadband faster and more stable, it can also increase the delay (latency) of your connection by up to around 40 milliseconds. While most people wouldn't normally notice this, it can adversely affect some delay-sensitive applications such as certain online games.
While interleaving can be switched off, we do not recommend doing so as it can lead to a less stable connection. There is a $30 charge (including GST) to switch interleaving on or off.
