You might have heard that AT&T U-Verse uses fiber-to-the-node, versus many cable companies, who probably stop a little earlier than that. But why is U-Verse’s max speed 24 Mbits/second (mbps)?
The reason is simple. AT&T uses DSL cables when the fiber optic cables arrive at the node. Yes, DSL, that slow crap you used to use. (Hopefully you use broadband now, right?…) Verizon, however, has the same set up, except they don’t use DSL at the node! The fiber optic cables arrive directly at the house, converting to coax afterwards.
