A T3 line is an especially powerful tool to transport data. The enormous capacity of a T3 line can be properly understood when it is compared with a T1 line.

While a T1 line can carry 24 separate channels thus providing 24 different sets of communication simultaneously, a T3 line can provide 672 channels! That is to say if there is one T3 line, 672 people can simultaneously browse the net at a very high speed.

T carriers do not have devoted channels. That is to say, no particular channel is attached to a particular telephone unit. It is basically a clutch of channels. Whenever a particular channel is used either to transfer data or used as a voice telephone, this channel is temporarily assigned to that activity. As soon as the activity is over the assigned channel reverts to the clutch.

Thus unless 24 people are simultaneously conversing, a user will always find a free channel. It has been observed that a single T1 line can very efficiently cater to 100-150 people in an office.

So, with 672 channels available in a single T3 internet connection, you can very easily realize that over 4000 people can simultaneously access the net at a very high speed or converse with crystal clear clarity.

T3 channels are almost invariably used by the internet service providers. With the data traffic it has to handle with the least possible delay and downtime, a provider has little option other than T3. They use this medium to remain connected with the internet backbone. At times the architecture of the backbone itself is made up of T3 connectivity.

The internet has revolutionized the whole concept of connectivity. With it has come the truly novel concept of e-commerce. Skeptics had earlier pooh poohed the concept of e-commerce. Their argument was that a retail customer will never buy a commodity unless he can physically check it.

But the success of retail portals like Amazon and EBay has stunned them into silence.

With the whole world becoming their marketplace due to the internet, big retail giants are now falling over one another to hike their bandwidths to the level of T3 to take advantage of reaching more customers simultaneously. This wide coverage and access which T3 connectivity can provide has provided them with the opportunity of multiplying their sales many many times over.

Not only the retail giants but capital goods manufacturers also have grabbed of this opportunity. They are now able to contact potential buyers all over the world and through video conferencing are able to demonstrate their products to clients and purchasers situated thousands of miles away – all in real time!

This new world of super fast and crystal clear connectivity has boosted the economies of not only the developed countries but the rest of the world too.

With breakneck competition raging among the service providers, the rates of T3 connectivity have also slid down from their previous forbidding heights. An intelligent comparison of the rates and schemes offered by the competing service providers and ruthless bargaining can further reduce the costs of T3 connection.
