What is the difference between DS3 and T3 bandwidth?

Not to be confused about the difference between DS3 and T3 circuits. These terms are really synonymous. Instead it should focus on obtaining what they can do for you ... and the best scenarios for the application.

Digital Signal (DS) is a system of classifying digital circuits according to the set and the format of the signal (DS) and the equipment providing the signals (T). DS and T designations have come to a synonym, so that DS1 implies use T1, and DS3 implies T3.

A DS3 line (also knownas T-3) is an ultra-high-speed connection capable of transmitting data at rates up to 45 Mbps. A DS3 line is approximately 672 regular voice-grade telephone lines, which is fast enough to forward to full-motion, real-time video and very large databases over a busy network. A DS3 line is typically as a major networking artery for large corporations and universities with high-volume network traffic installed. Other applications include large call centers, enterprise-wide VoIPand IP PBX systems, Internet service providers, research labs, video conference centers and software development company. A DS3 is offered the second best, not optical connection in North America. A DS3 line consists of 28 T1 lines, each operating at total signaling rate of 1.544 Mbit / s covers.

DS3 circuits provide businesses and Internet Service Providers (ISPs) with up to 45 Mbps of dedicated Internet connectivity. This is an ideal solution for users who have outgrown their T1Compounds and are able to access unlimited searching for, with high capacity. A DS3 line actually consists of 672 individual channels, each 64 Kb / s. DS3 are extremely high bandwidth connections into a carrier's backbone. They typically include SLAs (Service Level Agreements) that guarantee the availability and performance.

The DS3 signal itself is composed of 28 DS1 signals together and with the help of a two-step multiplex method. First, the 28 DS1 signals are multiplexed into seven DS2Signals. Second, the seven DS2 signals into a multiplexed DS3 signal. Each multiplexing step uses bit stuffing to handle the different input frequencies. Overhead bits provide alignment, error checking, in-band communication and bit stuffing control information.

Line rate: 44736000 b / s
Signals: 7 DS2 signals = 28 DS1 signals

Overhead bits:
A total of 56 bits / frame
F-bits (framing) 28-bit /
M-bits (multiframe) 3 bits /
C-bits (stuffing) 21-bit
X-bit(Message) 2 bits /
P-bit (parity) 2 bits /
Data bits between overhead bits 84

A DS3 connection of two monthly charges were composed of the local loop, and the port charge. The local loop charge is the cost for the circuit of the Local Exchange Carrier (LEC) that can DS3 access into the network of the carrier provided. The loop is free of the distance from the customer site to the edge of the network based carrier, the more the customer is from the network, the moreFree loop. Almost all vehicle prices loops differently so it is secure in your own interest, DS3 service with several suppliers for price to make sure you get the best deal.

DS Internet Access is the ideal solution for businesses that require high bandwidth at a reduced price. Whether you host high-traffic Web sites, support Web hosting or need high capacity bandwidth on an as needed, there is a level of DS3 service (full or fractional) that meets your needs. Fractionalfull DS3 or T3 lines from a speed of 3 Mbps to 45 Mbps.

For customers, the more bandwidth than a T1 line can provide, but not yet the capacity of a full DS3 line, a fractional DS3 connection required, the ideal solution. A fractional DS3 is similar to a full DS (T) 3, eliminated only with some of the channels. This will reduce the monthly cost and provides additional capacity that can be rotated in a matter of days. Unfortunately, the DS3 (T) loop is stillrequired for this service.

If a full DS3 line is more bandwidth, you really need, it is also possible to get Fractional DS3, which have a part to full DS3 bandwidth at a lower cost. Of course, DS3 is also increase many times the bandwidth, similar to T1-related services.

DS3 service can be used for a great truth of applications. The most common uses are DS3 point-to-point prices, DS3 internet, DS3 frame relay, DS3 voice and DS3 VPN. For thisCompounds varies by carrier, location of service and the application that is used for the connection.
