DS3 and DS

A DS3 connection is comprised up of two charges, which include the local loop and the port charge. The local loop is the cost of the circuit provided by the Local Exchange Carrier that allows DS3 access into the carrier's network. The loop charge the distance from the customer's location to the edge of the carrier's network; the farther the customer is from the network, the more the loop will cost. Nearly every carrier prices loops differently so it is in your best interest to price DS3 service with several providers to ensure that you get the best deal.

DS3 circuits provide businesses and Internet Service Providers (ISPs) with up to 45 Mb/s of dedicated Internet connectivity. A DS3 line actually consists of 672 individual channels, each of which supports 64 Kb/s. DS3 lines are extremely high bandwidth connections into a carrier's backbone. They typically include Service Level Agreements that guarantee uptime and performance.

The 28 DS1 signals are multiplexed into seven DS2 signals. In addition, the seven DS2 signals are multiplexed into one DS3 signal. Each multiplexing step uses bit stuffing to handle the different input frequencies. Overhead bits provide alignment, error checking, in-band communications, and bit stuffing control information.

A Digital Signal is a system that organizes digital circuits according to the rate and format of the signal and the equipment providing the signals. DS and T designations have come to be used synonymously. DS3 line is an ultra high-speed connection capable of transmitting data at rates up to 45 Mbps. A DS3 line is equal to about 672 regular voice-grade telephone lines, which is fast enough to transmit full-motion, real-time video, and very large databases over a busy network. A DS3 line is installed as a major networking artery for large corporations and universities with high-volume network traffic. Other example applications include large call centers, enterprise wide VoIP and IP PBX systems, Internet service providers, research labs, video conference centers and software development companies. A DS3 is the second fastest, non optical connection offered in North America. A DS3 line is comprised of 28 T1 lines, each operating at total signaling rate of 1.544 Mbps.

DS Internet Access is the ideal solution for businesses that require high-bandwidth access at a reduced price. Whether you host high-traffic Web sites, support Web hosting or need high-capacity bandwidth on an as-needed basis, there's a level of DS3 service (Full or fractional) that will meet your needs. Fractional to full DS3 or T3 circuits run from speeds of three Mbps up to forty-five Mbps.
