To determine the channel capacity, it is necessary to find the capacity-achieving distribution () and evaluate the mutual information (;). Research has mostly focused on studying additive noise channels under certain power constraints and noise distributions, as analytical methods are not feasible in the majority of other scenarios.
Some telecom providers also build a bit of intelligence (or meaning) into this unique prefix information. For instance, a T3U circuit type that carries a specific type of network traffic might use the HN designation at the beginning followed by a number in the 100-block for another specific purpose, 200-block for yet another purpose, and so on.
