What is T1?

T1 is a term commonly used to describe a specific type of leased telecommunication line. T1 lines are reserved circuits that use both copper or fiber-optic cables, and which are most commonly leased by businesses and other organizations on a monthly or yearly basis.

T1 lines provide efficient voice and data networking abilities, so businesses can easily stay connected with satellite offices and secondary locations. T1 lines consist of a circuit of up to 24 separate channels that transmit data at 64Kbps each, therefore giving a full T1 line the capacity to transmit 1.54 Mbps of data both sent and received.

The advantage of using one of these reserved circuits is that it guarantees a minimum amount of bandwidth at all times for network traffic, making them ideal for businesses which rely on Internet and other network use.
