Understanding T1 Circuits By Van Theodorou At Isnare.com Ezine Articles

T1 circuits are also high-speed digital connections, which can be used for voice or data. The T1 transmits data at a speed of 1.544 Mbps, which is faster than most modems.

T1s are engineered circuits that are used for businesses. The T1 consists of 24 channels, which can be allotted to voice, data or both. The T1 transmission occurs over two-pair fiber wiring however it is sometimes brought to the building on regular copper wires.

The circuit is specifically engineered based on the distance from the central office where it originates to the final location where it will terminate. The circuit must transmit at specific speeds and repeaters are sometimes needed to help boost the signal.

T1 circuits are brought into the business and terminated onto a jack in the telephone or data room. The jack, called a smart jack, can then be used to plug a cable to extend the circuit into the appropriate equipment. This takes up considerably less space in the telephone room than standard telephone lines.

Voice T1s can be used for both incoming and outgoing calls. The 24 circuits are fluid and are available to any telephone users when they become available. This allows the best usage of the lines. Sharing the lines in this manner lets you have many fewer lines than before. For example, an office of 50 to 100 people with average telephone needs can easily be serviced with one T1.

Voice T1s can also be used with DID (direct inward dial) numbers. DIDs are like private lines. Each telephone user can be assigned a DID number from a bank of numbers that you order through the phone company. The DID numbers run over the T1 and can each be assigned to a specific telephone. The DIDs are able tot be dialed directly from the outside with no intervention from the company operator for re-direction.

For larger companies that need more lines or those that need additional bandwidth there are bigger configurations available. The T3, also known as a DS3, is a digital communications link that supports data at a rate of 43.232 Mbps. It is equal to 28 T1 circuits. This high-speed connection can run any application you may need. If you have a large company or campus environment the T3 may be a good option. It is also a good option for those with phone intensive operations such as a call center.

The T1 can’t be beat for clarity, reliability and cost efficiency. It is a highly reliable connection. The T1 is always being monitored at the central office and if any problems are detected they can often be corrected remotely. The T1 offers a clear, crisp sound as well. The T1 is also quite cost efficient.

While there are typically installation charges these are often made up in the first year, or sooner. Users find monthly charges are often much less than what they were paying before. The additional features and benefits add to the value of the T1. The best thing to do is talk to an telecom agent to see if going the way of a T1 is best for your company.
