MNP7

OBS: Il intègre un algorithme de compression plus performant : pour un taux de compression de MNP5 égal à 2, MNP7 donne un taux de 3.

OBS: This class integrates a more efficient data compression method than the one used in Class 5. Class 7 provides an average 300 percent improvement. Class 7 data compression uses Huffman encoding with a predictive algorithm to represent user data in the shortest possible Huffman codes. In addition to Class 5 and Class 7 data compression, MNP also supports V.42bis data compression. Based on the Lempel Ziv data compression model, V.42bis supports an average 400 percent efficiency improvement.
