"Stepping Up To The DS-3 Line"

What exactly are DS3 lines? Often used interchangeably, the DS-3 line and the T3 line are pretty much the same thing. Sometimes the DS-3 lines are described as the "internal office" connection, while the T-3 is used to describe the same line once it leaves the building.

Another school of thought refers to the DS-3 line as the framing, or "format" of the digital transmission signal, while the T-3 line is referred to as either the facility used to transmit the signal, or sometimes even as the "type" of connection.

AT&T was the first to use the term "DS-3" (an acronym for Digital Signal Level 3) to describe the DS-3 line's place within the digital hierarchy. A DS-3 line has the transmission power of 28 DS-1 lines.

This is equivalent to 672 separate channels of 64 kilobytes per second (kbps) of digital transmission.

That is a lot of transmission power! In your search for top of the line telecommunications services, the DS-3 lines are worth stepping up to for your company's needs.
