Mathematics and Models for Autopoiesisross-country service through the use of multiple repeater sites. Thus individual circuit lengths range from less than 30 km to over 6400 km with route cross-sectional capacities from less than 60 to more than 22 000 circuits. Applications include not only telephone message channels but also wideband data and television transmission.
