What are T1 and T3 Internet Connections and Who Uses Them?
T1 and T3 lines are basically leased lines, which are used in the field of telecommunications. They are an example of reserved circuit communication that works through fiber optic cables and copper wiring. They are called ‘leased lines’ because they are leased by companies to form connections between offices for the purpose of networking offices in different locations. They are quite expensive to rent which is probably why it is mostly corporations that use them. T1 lines are use in accordance with the T1 standard, created by AT&T. there transmission rate is that of symmetric DSL (1.5mbps). Fractional T1 lines operate at 128kbps ad are a little lower in cost, so it might not be too surprising to find them in heavily residential buildings. T1 and T3 are both examples of high-speed telephone lines. Both of them may be used to provide broadband internet access. Technically, a T1 connection is a fiber-optic or copper line that is separate from the regular phone line. However, the T1 line can be used for both broadband Internet access in addition to phone purposes. T1 and T3 lines are commonly used by businesses because they offer very fast data transfer rates. This is appealing to businesses that need to transfer large amounts of data each day. Additionally, T lines provide very reliable forms of Internet access, with “always on” capability and very few incidences of lost Internet connections. In terms of speed, T1 lines operate at 1.5 Mbps, and T3 lines operate at 44.6 Mbps. In other words, T3 lines are about 30 times faster than T1. These high speeds are very useful for heavy Internet traffic situations as well as for situations in which a network must be accessed by a larger number of users. A T1 line operating at full capacity can accommodate up to 24 users working at 64 Kbps. Businesses that require very fast broadband...
