   The short article on telco provided Internet was interesting. Here in   
   Arvada CO (just west of Denver), we have DSL from CenturyLink. It uses   
   two pairs and delivers 140 Mbps down and 20 Mbps up. I'm really im-   
   pressed with what they can shove down a pair of wires!   
      
   My first DSL was in San Luis Obispo CA from Pacific Telephone. I think   
   it was about 1.5 Mbps down. About as fast as a T1. Who would ever need   
   more?   
      
   Then we moved to Santa Maria CA and got 6 Mbps down. Wow!   
      
   And now 140 Mbps down.   
      
   NOTE that I am not in any way associated with Century Link, though I   
   do volunteer for the Telecom History Group that has space from ATT and   
   CenturyLink in Denver. I am just impressed with the advances in   
   DSL. They are shoving a lot of data down a pair of wires.   
      
   The 140 Mbps measured peak speed using Measurement Lab. The speed does   
   vary with time of day. Right now, it's the slowest I've ever seen it   
   at 35.5 Mbps up, 11.5 Mbps down. We are listening to streaming audio   
   right now, so that takes a little. Looking at the status page on the   
   Zyxel C3330Z modem, I see 78.223/11.196 for the first pair and   
   68.638/11.196 for the second pair. That, of course, is just the links   
   from here to the DSLAM.   
      
   Looking at my bill, Century Link just calls it "140 Mbps High Speed   
   Internet." I think the use of two pairs is unique, but otherwise it   
   seems to be what current DSL can do over relatively short loops. It   
   looks like the DSLAM is about a block away from us.
