Written by: Les Harper - Nov 20, 2008

DS3 (Digital Signal 3)

64 kbps is called digital signal zero, or DS0, and is not considered to be a high-speed line nowadays; the minimum for high-speed transmission is about 24 times faster than DS0, and is called DS1. This is more familiar as a “T1” line. A dedicated T1 line is always on, transmitting and receiving the equivalent of 24 voice conversations from the Internet provider’s servers. A large company needs something more than a T1 line and could probably use a T3 line powered by DS3 technology.

Major telecom providers typically offer a range of services and speeds, including DS3; for example Verizon, AT&T, Sprint. Followings are the details of few DS3 service providers.
