T-Carrier - A Complete and Comprehensive Guide

What is T1 Line?

Have you heard of the latest internet technology that was developed by the AT&T Bell Labs that is being utilized in North America and Japan? It is described and referred to as a particular type of copper or fiber optic telephone line that has the ability of handling more data compared to that of telephone lines. Have I already stirred your curiosity? Lo and behold as we make way for this latest development, the T1 line. A T1 line has the capacity of transmitting 1.544 Mbps and it can also be used to send 24 digitized voice channels that can be used for phone service in commercial buildings and other establishments.

In the past, twisted copper telephone lines were the standard that lasted for decades. These copper lines were used for the transmission of voice and data through analog signals. As time progresses, the standard also was slowly upgrading into fiber optic lines out of bundled glass fibers, however, most T1 lines used today are still made of twisted copper. T1 lines created a 'pipe' which, as I have mentioned earlier, makes it capable f blowing through larger data streams.

The price, however of this amazing T1 line can be very expensive. But don't you guys fret since it has been a tradition in the world of technology that costs can increasingly drop when the demand grows. Internet service providers or commonly known as ISPs are very accommodating their clients when they want to lease T1 lines to provide service to their wide network of clients.

There are also other multiplexed fiber optic lines such as T2 and T3 lines and they has the capacity to transfer data to up to 44.736 Mbps. T3 lines are equivalent to having 28 T1 lines and is being utilized by larger establishments that has higher data and voice needs and demands. There are also more advance T-standards that are existing but they are not high in use.

Meanwhile, the European Union uses a different and incompatible type of carrier line which is called as the E1 and the E3. E2 lines are available as well but these types of lines are less common.

In general, T1 lines can not be cost-efficient for individual or residential use and in this case, having a DSL or a cable service could be the better choice. Small businesses and government agencies, on the other hand - specifically those that are using PBXs can greatly benefit from a T1 line.

Types of T1 line

T1 circuits are oftentimes referred to as 'always on' connections. It does not resemble a voice circuit that can only yield expenses when a call is placed. With this reason, T1s are sometimes used as private lines or dedicated data lines because they are always utilized even though the data is being transmitted or not. Hence, it can never be used for handling traffic coming from multiple subscribers.

However, the most obvious downside of having a T1 line is its cost. T1 lines provide very fast and dependable connections, but you will pay for that guaranteed uptime. For a lot of businesses that depend heavily on employee and customer access to data and other applications, I assure you that T1s are really worth the investment.
