There are many different types of telecommunication services in use today. Land lines, aka plain old telephone service, are slowly taking a back seat to new advances in wireless technology. Small and large businesses are currently using wireless and fiber services to expand their businesses. These are just a few of the telecommunications services reshaping the world today. As computers get faster and smarter, more data gets moved from one place to another via telecom services.
POTS lines are defined as plain old telephone service lines. In the old days, everyone had a POTS line, aka land line. This service has only one purpose, which is to transport voice calls to anywhere in the country or world. POTS lines do not have a very large bandwidth. POTS usually operate at no more than 52 Kilobits per second. One bit refers to one bit of information in the binary language used by computers. It's value is "0" or "1." 52 Kilobits per second means 52,000 bits of data can be transmitted within 1 second. This is the maximum speed at which data is moved in this type of circuit.
T1 lines have a higher bandwidth than POTS lines and have the ability to carry more information. T1 lines operate at 1.54 megabits per second. These lines are primarily used to carry data such as computer communications and data. 1.54 megabits per second means 1,540,000 bits of data can be transmitted within 1 second. This is the maximum speed at which data is moved in this type of circuit.
Metro Ethernet has a wide bandwidth due to the fact that most metro Ethernet circuits are delivered over fiber instead of regular copper. Metro Ethernet services have speeds that range from three megabits per second up to one Gigabit per second. These circuits are used in small and large businesses for communication between offices around the world. Three megabits per second means 3,000,000 bits of data can be transmitted within one second. One Gigabit per second means 1,000,000,000 bits of data can be transmitted within one second.
