E' possibile farsi una ADLS privata utilizzando un doppino telefonico privato esistente (anche i cavi del citofono)
Raggiunge una velocita' di 10 megabit full duplex al secondo (VDLS) e arriva ad una distanza di circa un chilometro.
Non c'e' nulla da configurare, da una parte si attacca al doppino telefonico privato (non Telecom!) e dall'altra c'e' una presa Ethernet.
