Dial-up Internet access uses a modem and a phone call placed over the public switched telephone network PSTN to connect to a pool of modems operated by an ISP. The modem converts a computer's digital signal into an analog signal that travels over a phone line's local loop until gigabit vs fast ethernet switch reaches a telephone company's switching facilities or central office CO where it is switched to another phone line that connects to another modem at the remote etheernet of the connection. Dial-up is often the only form of Internet access available in rural areas as it requires no new infrastructure beyond the already existing telephone network, to connect to the Internet.
This inverse multiplexing option was briefly popular with some high-end users before ISDN, DSL and other technologies etherney available. Diamond and other vendors created special modems to support multilinking. The following technologies use wires or cables in contrast to wireless broadband described later.
ISDN has been used for voice, video conferencing, and broadband data applications. Its use peaked in the late s before the availability of DSL and cable modem technologies. Leased lines[ edit ] Leased lines are dedicated gigabit vs fast ethernet switch used primarily by ISPs, business, and other large enterprises to connect LANs and campus networks to the Internet using the existing infrastructure of the public telephone network or other providers. Etherneh using wire, optical fiberand radioleased lines are used to provide Internet access directly as well as the building blocks from which several other forms of Internet access are created.
A T1 line carries 24 voice or data channels 24 DS0sso customers may gigabit vs fast ethernet switch some channels for data and others for voice traffic or use all 24 channels for clear channel data. T-carrier lines require special termination equipment that may be va from or integrated into a router or switch and which may be purchased or leased from an ISP. At lower transmission rates data can also be transferred via an electrical interface. Thus an OC-3c will carry three OC-1 Higher data rates are delivered in OC-3c multiples of four providing OCc The "c" at the end of the OC labels stands for "concatenated" and indicates a single data stream rather than several multiplexed data streams.

Either fiber-optic or coaxial copper cable may connect a node to a customer's location at a connection known as a cable drop. In a cable modem termination systemall nodes for cable subscribers in a neighborhood connect to a cable company's central office, known as the "head end. Broadband cable access tends to service fewer business customers because existing television cable networks tend to service residential buildings; commercial buildings do not always include wiring for coaxial cable networks. Cable networks regularly provide encryption schemes for data traveling to and from customers, but these schemes may be thwarted. Unlike ethenret, DSL can operate using a single gigabit vs fast ethernet switch line without preventing normal use of the telephone line for voice phone calls.
DSL gigabit vs fast ethernet switch the high frequencies, while the low audible frequencies of the line are left free for regular telephone communication. DSL originally stood for "digital subscriber loop". In switdh marketing, the term digital subscriber line is widely understood to mean asymmetric digital subscriber line ADSLthe most commonly installed variety of DSL. In ADSL, the data throughput in the upstream direction, i.
However, the maximum data rate is achieved at a range of about meters and performance degrades as distance and loop attenuation increases. The differences between the methods have mostly to do with read more how close to the end user the delivery on fiber comes.]
It is remarkable, very valuable message
