what does dsl stand for

Early DSL service required a dedicated dry loop, but when the U.S. Federal Communications Commission (FCC) required incumbent local exchange carriers (ILECs) to lease their lines to competing DSL service providers, shared-line DSL became available. Researchers at Bell Labs have reached speeds over 1 Gbit/s for symmetrical broadband access services using traditional copper telephone lines, though such speeds have not yet been deployed elsewhere. Naked DSL is a way of providing only DSL services over a local loop. Gradle is an open-source build-automation system that builds upon the concepts of Apache Ant and Apache Maven and introduces a Groovy-based domain-specific language (DSL) instead of the XML form used by Apache Maven for declaring the project configuration.. The commercial success of DSL and similar technologies largely reflects the advances made in electronics over the decades that have increased performance and reduced costs even while digging trenches in the ground for new cables (copper or fiber optic) remains expensive. Generally, higher bit rate transmissions require a wider frequency band, though the ratio of bit rate to symbol rate and thus to bandwidth are not linear due to significant innovations in digital signal processing and digital modulation methods. The DSLAM terminates all connections and recovers the original digital information. See other definitions of DSL. It is useful when the customer does not need the traditional telephony voice service because voice service is received either on top of the DSL services (usually VoIP) or through another network (E.g., mobile telephony). Bit rates of 1 Gbit/s have been reached. DSL offers a diverse range of features across the entire series including power reduction, studio quality reverb and two footswitchable channels. The two main pieces of equipment are a digital subscriber line access multiplexer (DSLAM) at one end and a DSL modem at the other end. It provides online services through the same network as that of telephone lines. This means that internet providers are able to transmit digital data—like computer code—over a phone line. The local loop connecting the telephone exchange to most subscribers has the capability of carrying frequencies well beyond the 3400 Hz upper limit of POTS. Many DSL technologies implement an asynchronous transfer mode (ATM) layer over the low-level bitstream layer to enable the adaptation of a number of different technologies over the same link. It is common for a few residential blocks to be connected to one DSLAM. Their initialization is very similar to a PC boot up.

But ADSL loop extenders increase these distances by repeating the signal, allowing the LEC to deliver DSL speeds to any distance.[8]. You'd probably look at it and think it means top-notch, but in French the abbreviation stands for à plus tard or see you later. Advertisement: This definition appears rarely. A+ (à plus tard) A+ doesn't carry the same meaning in French texting as it does in English. Telephone companies were also under pressure to move to ADSL owing to competition from cable companies, which use DOCSIS cable modem technology to achieve similar speeds. VDSL is used as a method of delivering "triple play" services (typically implemented in fiber to the curb network architectures). Older ADSL standards delivered 8 Mbit/s to the customer over about 2 km (1.2 mi) of unshielded twisted-pair copper wire. This frequency band separation enables DSL service and plain old telephone service (POTS) to coexist on the same cables. The location of the DSLAM depends on the telco, but it cannot be located too far from the user because of attenuation between the DSLAM and the user's DSL modem. There are a few types of internet, dial-up (uses a land-line) but is billed as a phone bill to access the internet. See other definitions of DSL. Digital subscriber line (DSL; originally digital subscriber loop) is a family of technologies that are used to transmit digital data over telephone lines. Filters are added to prevent the clash between the internet connection and phone calls. All content on this website, including dictionary, thesaurus, literature, geography, and other reference data is for informational purposes only. The theoretical foundations of DSL, like much of communication technology, can be traced back to Claude Shannon's seminal 1948 paper: A Mathematical Theory of Communication. yes. [1], In ADSL, the data throughput in the upstream direction (the direction to the service provider) is lower, hence the designation of asymmetric service. Unlike these traditional phone signals, DSL signals only travel from the provider, to the subscriber. Advertisement: This definition appears somewhat frequently. Fast channel is preferred for streaming multimedia, where an occasional dropped bit is acceptable, but lags are less so. The DSL series has one master volume for each channel means that you can create explosive solo moments. The bit rate of consumer DSL services typically ranges from 256 kbit/s to over 100 Mbit/s in the direction to the customer (downstream), depending on DSL technology, line conditions, and service-level implementation. Cable, which uses TV … Stand out from the crowd. For residential variations of DSL, this is usually the, Internet Protocol subscriber line (IPSL), developed by Rim Semiconductor in 2007, allowed for 40 Mbit/s using 26, This page was last edited on 28 December 2020, at 16:06. Transmission methods vary by market, region, carrier, and equipment. DSL stands for Digital Subscriber Line. A guy told me I had DSL and when I googled it, it says Digital Subscriber Line, which makes no sense... Update: Okay it made no sense because a guy randomly came up to me and told me I had nice DSL. Most DSL technologies require installation of appropriate filters to separate, or split, the DSL signal from the low-frequency voice signal. DSL: [noun] acronym for "dick sucking lips." ADSL supports two modes of transport: fast channel and interleaved channel. What does DSL filter do. Dumb Stupid Loser. Your girlfriend has some great goddamn DSL . The company was founded in the United States in 1969 and expanded its service throughout the world by the late 1970s. Only one DSL modem can use the subscriber line at a time. DSL and RADSL modulations do not use the voice-frequency band so high-pass filters are incorporated in the circuitry of DSL modems filter out voice frequencies. The separation can take place either at the demarcation point, or with filters installed at the telephone outlets inside the customer premises. The system image is loaded from the flash storage; the system boots, synchronizes the DSL connection and finally establishes the internet IP services and connection between the local network and the service provider, using protocols such as DHCP or PPPoE. suggest new definition. What's dsl stand for? Also known as DSL over unbundled network element, this unbundling of services allows a single subscriber to receive two separate services from two separate providers on one cable pair. In this case, the equipment is referred to as a gateway. On the customer premises, a DSL filter on each non-DSL outlet blocks any high-frequency interference to enable simultaneous use of the voice and DSL services. Due to the advancements of very-large-scale integration (VLSI) technology, the cost of the equipment associated with a DSL deployment lowered significantly. Once again, it proved my theory that it's virtually impossible to get a bad blow job from a fat chick . Series of transfer standards in data transmission, "DSL" redirects here. A guy told me I had pretty nice DSL the other day. In other cases (particularly ADSL), it is common for the customer equipment to be integrated with higher level functionality, such as routing, firewalling, or other application-specific hardware and software. Most homes and small business users are connected to an asymmetric DSL (ADSL) line. This information should not be considered complete, up to date, and is not intended to be used in place of a visit, consultation, or advice of a legal, medical, or any other professional. Longer lines that require them can be replaced with fiber to the neighborhood or node (FTTN). The customer end of the connection consists of a terminal adapter or "DSL modem". DHL (Dalsey, Hillblom and Lynn) International GmbH is a German courier, parcel, and express mail service which is a division of the German logistics company Deutsche Post DHL. Each way has its practical and economic limitations. [14] The system image can usually be updated to correct bugs, or to add new functionality. DSL stands for Digital Satellite Links. However, these cables had other impairments besides Gaussian noise, preventing such rates from becoming practical in the field. Voice service cannot be maintained past a certain distance without such coils. Engineers developed high speed DSL facilities such as high bit rate digital subscriber line (HDSL) and symmetric digital subscriber line (SDSL) to provision traditional Digital Signal 1 (DS1) services over standard copper pair facilities. But yes, that is what DSL stands for. DSL implementations may create bridged or routed networks. Can both a phone and PC be used simultaneously on ADSL. As a result of AT&T's merger with SBC,[12] and Verizon's merger with MCI,[13] those telephone companies have an obligation to offer naked DSL to consumers. It is a term used to describe a range of high-speed (broadband) communications services offered over the Public Switched Telephone Network (PSTN). Once upstream and downstream circuits are established, a subscriber can connect to a service such as an Internet service provider or other network services, like a corporate MPLS network. If you are a webmaster of non-commercial website, please feel free to publish the image of DSL definitions on your website. This means that your download speed – all the data coming to your device – will be faster than your upload speed – any data going from your device to the internet. All types of DSL employ highly complex digital signal processing algorithms to overcome the inherent limitations of the existing twisted pair wires. It is also commonly called an unbundled network element (UNE) in the United States; in Australia it is known as a unconditioned local loop (ULL);[10] in Belgium it is known as "raw copper" and in the UK it is known as Single Order GEA (SoGEA).[11]. digital subscriber line. Other Resources: Acronym Finder has 65 verified definitions for DSL. The DSL transceiver performs a self-test, including image load and activation. DSL: Désolé (French: sorry) DSL: Dictionary of the Scots Language: DSL: Damn Small Linux: DSL: Digital Subscriber Loop (less common) DSL: Division of State Lands (US Army Corps of Engineers) DSL: Digital Signal Level: DSL: Division of Student Life (various schools) DSL: Definitive Software Library: DSL: Deep Scattering Layer: DSL: Digital Subscriber Line: DSL: Digital Subscriber Loop Therefore, some areas that are within range for DSL service are disqualified from eligibility because of loading coil placement. It builds connections through phone lines. Click to see full answer People also ask, which DSL does gradle use? What does DSL stand for? The pool of usable channels is then split into two different frequency bands for upstream and downstream traffic, based on a preconfigured ratio. What does DSL stand for? The company delivers over 1.3 billion parcels per year. Most residential and small-office DSL implementations reserve low frequencies for POTS, so that (with suitable filters and/or splitters) the existing voice service continues to operate independently of the DSL service. Internet Speeds for your needs • AT&T Internet offers a range of Broadband plans up to 100Mbps and gives you reliable streaming (even multiple streams in high definition) and online gaming. [4], The motivation for digital subscriber line technology was the Integrated Services Digital Network (ISDN) specification proposed in 1984 by the CCITT (now ITU-T) as part of Recommendation I.120, later reused as ISDN digital subscriber line (IDSL). Possible DSL meaning as an acronym, abbreviation, shorthand or slang term vary from category to category. This data is transmitted at a different frequency from a phone call, so, unlike dial-up, you … Search for DSL in Online Dictionary Encyclopedia. The telephone company connects the other end of the line to a DSLAM, which concentrates a large number of individual DSL connections into a single box. The local loop was originally intended mostly for the transmission of speech, encompassing an audio frequency range of 300 to 3400 hertz (commercial bandwidth). In the case of ADSL, the voice component is also separated at this step, either by a filter integrated in the DSLAM or by a specialized filtering equipment installed before it. ; What does DSL mean? DSL brings a connection into your home through telephone lines and allows the household to use the Internet and make telephone calls at the same time. DSLR is the abbreviation for Digital Single Lens Reflex. It started making a comeback in the United States in 2004 when Qwest started offering it, closely followed by Speakeasy. digital subscriber line, DSL (noun) a generic name for digital lines that are provided by telephone companies to their local subscribers and that carry data at high speeds Rap Dictionary (0.00 / 0 votes)Rate this definition: DSL service can be delivered simultaneously with wired telephone service on the same telephone line since DSL uses higher frequency bands for data. The standard way to let multiple computers share a DSL connection uses a router that establishes a connection between the DSL modem and a local Ethernet, powerline, or Wi-Fi network on the customer's premises. ?. This is different from rangefinder and twin-lens-reflex constructions. Turn up the gain. By 2012, some carriers in the United States reported that DSL remote terminals with fiber backhaul were replacing older ADSL systems.[9]. Reflexrefers to a system where a mir… Computer DSL abbreviation meaning defined here. The following image presents the most commonly used meanings of DSL. The 1980s saw the development of techniques for broadband communications that allowed the limit to be greatly extended. DSL takes advantage of this unused bandwidth of the local loop by creating 4312.5 Hz wide channels starting between 10 and 100 kHz, depending on how the system is configured. new search. Other Resources: Acronym Finder has 65 verified definitions for DSL. The accompanying figure is a schematic of a simple DSL connection (in blue). On the subscriber's end of the circuit, inline DSL filters are installed on each telephone to pass voice frequencies but filter the high-frequency signals that would otherwise be heard as hiss. In telecommunications marketing, the term DSL is widely understood to mean asymmetric digital subscriber line (ADSL), the most commonly installed DSL technology, for Internet access. Possible DSL meaning as an acronym, abbreviation, shorthand or slang term vary from category to category. In symmetric digital subscriber line (SDSL) services, the downstream and upstream data rates are equal. what does DSL stand for. Such deployment, even including equipment, is much cheaper than installing a new, high-bandwidth fiber-optic cable over the same route and distance. showing only Slang/Internet Slang definitions ( show all 65 definitions) Note: We have 250 other definitions for DSL in our Acronym Attic. A DSL circuit terminates at each end in a modem which modulates patterns of bits into certain high-frequency impulses for transmission to the opposing modem. [2][3], It was originally thought that it was not possible to operate a conventional phone line beyond low-speed limits (typically under 9600 bit/s). The right side shows a DSLAM residing in the telephone company's telephone exchange. Like analog modems, DSL transceivers constantly monitor the quality of each channel and will add or remove them from service depending on whether they are usable. Because DSL operates above the 3.4 kHz voice limit, it cannot pass through a loading coil, which is an inductive coil that is designed to counteract loss caused by shunt capacitance (capacitance between the two wires of the twisted pair). ADSL divides up the available frequencies in a line on the assumption that most Internet users look at, or download, much more information than they send, or upload. Also, nonlinear elements in the phone could otherwise generate audible intermodulation and may impair the operation of the data modem in the absence of these low-pass filters. We know 375 definitions for DSL abbreviation or acronym in 8 categories.
