VDSL-Very High Bit-Rate DSL

-Boasts a much higher bandwidth capacity.

SDSL-Symmetric DSL

-Connection is 1.168 Mbps -Connections are usually limited to a maximum distance of 12,000 ft.

SDSL-Symmetric DSL

-Does not allow simultaneous voice and data on the same phone line.

VDSL-Very High Bit-Rate DSL

-Downstream limit of 52 Mbps and a limit of 12 Mbps for upstream traffic. -VDSL's distance limitation is 4000 ft. of telephone cable between a cable modem and a DSLAM

SDSL-Symmetric DSL

-Has asymmetric (unequal) upstream and downstream speeds, by definition -SDSL has symmetric (equal) upstream and downstream speeds. -Does not allow simultaneous voice and data on the same phone line. --Less popular in residential installations because an additional phone line is required for data. -Connection is 1.168 Mbps -Connections are usually limited to a maximum distance of 12,000 ft.
