Grandma’s Phone, DSL, and the Copper They Share

My DSL line downloads at 6 megabits per second. I just ran the test. This is over a pair of copper twisted wires, the same Plain Old Telephone Service (POTS) twisted pair that connected your Grandmother’s phone to the rest of the world. In fact, if you had that phone you could connect and use it today.http://hackaday.com/2016/02/05/grandmas-phone-dsl-and-the-copper-they-share/
