HDSL
HDSL services bring the opportunity of having a better link quality than ADSL, and moreover it is available even in most areas where ADSL is not yet operative. These kind of services are all "flat", so there is only a fixed cost each month, indipendently from the quantity of time it is being used or the quantity of data transmitted/received. There are several bandwidth sizes, starting from 192Kbps to 2Mbps.
