Many people are baffled between T3 and DS3 circuits. Don’t be confused by this because they're generally similar. Instead, you will need to completely focus in what they're capable of giving, as far as benefits. Concentrate oneself in the best conditions of the applications they will supply.

To really make it easier for you to understand, why don't we carefully identify these two circuits. Digital Signal (DS) is simply a system applied to distinguishing these digital circuits depending on the format and rate of the signal (DS), together with machine that give the signals (T). Each of them (DS &T) are being used synonymously to imply that DS1 is designed for T1 and DS3 is good for T3.

A T3 line ( also known as DS3) is a high-speed connection which is dependable in transmitting data at the speed of 45 Megabyte per second. In contrast, a DS3 line is equivalent to at least 672 typical phone lines. It is quick enough to open a full-motion video and huge database in a busy network. Educational institutions and massive corporations normally install DS3 line as their networking artery, because these firms have high volume of traffic. There are also some other companies that have high volume of traffic such as the internet service providers, video conference centers, call centers, research labs, enterprise-wide IP PBX and Voice over internet protocol systems, and also other software development firms.

In North America, the second fastest non-optical connection presented is the DS3 line. DS3 is comprised of twenty eight T1 lines. That’s how incredible they could work for your businesses. Each line works a total signal rate of 1.544 Mbps.

As much as forty five Mb/s of committed internet connection might be given by the DS3 circuits to businesses, along with the internet service providers. This is already regarded by regular users as an ultimate solution for users that want to get endless accessibility. The DS3 is also comprised of twenty eight DS1 installed using a multiplexing procedure.

Line rate: 44,736,000 b/s

Signals: 7 DS2 signals = 28 DS1 signals

Overhead bits:

56 bits total/frame

F-bits (framing) 28 bits/

M-bits (multiframing) 3 bits/

C-bits (stuffing) 21 bits

X-bits (message) 2 bits/

P-bits (parity) 2 bits/

Data bits between overhead bits 84

If we as well touch about a DS3 connection, it is made-up no less than 2 monthly charges: the port charge and the so-called local loop. It is the Local Exchange Carrier (LEC) that is providing the local loop charge, allowing DS3 access. The loop charge is always based on the customers’ location to the carrier’s network. That means the farther the client from the network, the higher also is the loop charge. DS internet access is really a very great business solution, primarily for businesses that must have high bandwidth access.
