What is a DS3 line?

A DS3 line (sometimes also referred to as T3) is a dedicated, high bandwidth, fiber circuit with a speed of 45 Mbps. This is equivalent to 28 T1 lines (or 672 regular phone lines). A DS3 circuit provides businesses that have a high amount of data traffic, the bandwidth they need - plugging straight into the carrier's backbone. DS3 bandwidth is mostly used as high speed internet access for business applications, often when companies outgrow their bonded t1 circuit speed. Some common applications for a ds 3 circuit are:

  • Videoconferencing.
  • Voice communications.
  • Voice/data aggregation.
  • Electronic data interchange.
  • Expanding backbone network
