....network connections in the world. In fact, it is necessary to define the telephone channel statistically, because no fixed definition is practical. Extensive studies of the telephone network have been made in different parts of the world. In North America, the telephone channel has been studied in [49], and [50] In Table 4.1.2.1, we summarize some of its main conclusions.
