ADSL works over wet string? Now, what about "ADSL over a UNPLUGGED phone line"? During a building-wide copper to fiber upgrade, the phone company stupidly unplugged my phone line from the distribution box. the phone was completely dead, no voltage. But my ADSL modem could complete the handshake. Speed degraded to ~128 Kbps, but I could still read basic webpages or chat on IRC... Apparently the parasitic capacitance on the line was enough for the AC signal to jump across the gap. My best guess was that only the ground wire was lost, and the parasitic capacitance of the modem's isolation transformer could complete the circuit via the mains powerline.
