ADSL over wet string
I once had an issue where my phone line was completely dead, but I was still getting ADSL, just at very slow speeds. In the order of 1mbit.<p>After the technician came he told me that one of the two phone line wires had been broken off at the exchange.<p>In other words, there wasn't a complete electrical circuit.<p>The phone was dead but ADSL still works without even having a complete circuit.<p>I don't even understand how that can work at all.
