Re: [Speed] Comcast Cable vs. AT&T U-verse ?
said by tshirt  :AT&T U-verse tends to quote the sync speed, DSL does have around 15% overhead ... Not all DSL is the same. Verizon, Qwest (I think), AT&T Southeast, and some others "oversynch"; such that your throughput is close to advertised because they adjust for the overhead. It is my understanding that AT&T Uverse VDSL will be closer to the advertised speed than their ADSL product.
... and your must also subtract what other services (TV, Phone) uses.
Actually, that depends. If they are selling 18 Meg Internet, they are probably using bonded pairs to double the capacity of the wire. One pair is good for 24-25 Mb/s; bonded pair doubles that. Their first deployment limited DSL to 6 Mb/s because they reserved the rest of the bandwidth for IPTV.
beyond the local box you share the fiber to the CO with neighbors, just like cable.
But that is the fiber part of the network. The "Last Mile" copper is not shared.
