what does dsl stand for

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. Each channel is evaluated for usability in much the same way an analog modem would on a POTS connection. Search for DSL in Online Dictionary Encyclopedia. The local loop was originally intended mostly for the transmission of speech, encompassing an audio frequency range of 300 to 3400 hertz (commercial bandwidth). 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. Older ADSL standards delivered 8 Mbit/s to the customer over about 2 km (1.2 mi) of unshielded twisted-pair copper wire. The underlying technology of transport across DSL facilities uses modulation of high-frequency carrier waves, an analog signal transmission. What does ADSL stand for. DSL stands for Digital Subscriber Line. DSL stands for digital subscriber line. Turn up the gain. 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. DSL technologies (sometimes collectively summarized as xDSL) include: The line-length limitations from telephone exchange to subscriber impose severe limits on data transmission rates. The lowest band allows for telephone calls, while the other two bands take care of uploading and downloading online activity. This means that your download speed â all the data coming to your device â will be faster than your upload speed â any data going from your device to the internet. A+ (à plus tard) A+ doesn't carry the same meaning in French texting as it does in English. [5] A patent was filed in 1988.[6]. In this case, the equipment is referred to as a gateway. DSL Stands For: All acronyms (375) Airports & â¦ Computer DSL abbreviation meaning defined here. 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. DSL, which does the same thing except phone companies process the information differently. 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. This segregation reduces interference. DSL stands for Digital Subscriber Line and refers to a high-speed internet technology offered over telephone lines by Internet Service Providers.It belongs to a category of technologies that enable broadband internet access, along with the internet services offered over cable or fibre optic. ; What does DSL mean? 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. 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. The following image presents the most commonly used meanings of DSL. The pool of usable channels is then split into two different frequency bands for upstream and downstream traffic, based on a preconfigured ratio. ?. 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. yes. Dumb Stupid Loser. DSL implementations may create bridged or routed networks. Most homes and small business users are connected to an asymmetric DSL (ADSL) line. This is true both for ADSL and SDSL variations. The DSL service provider's equipment is co-located in the same telephone exchange as that of the ILEC supplying the customer's pre-existing voice service. Once the channel groups have been established, the individual channels are bonded into a pair of virtual circuits, one in each direction. 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. The DSLAM terminates all connections and recovers the original digital information. Cable companies provide a cable modem foâ¦ What does DSL stand for? 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. 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: The DSL transceiver performs a self-test, including image load and activation. Cable, which uses TV â¦ Therefore, some areas that are within range for DSL service are disqualified from eligibility because of loading coil placement. The 1980s saw the development of techniques for broadband communications that allowed the limit to be greatly extended. ; What does DSL mean? What does DSL stand for in Texting? 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. Thus POTS-based communications, including fax machines and dial-up modems, can share the wires with DSL. A guy told me I had pretty nice DSL the other day. It works because the DSL system separates the telephone signals into three bands of frequencies. Due to the advancements of very-large-scale integration (VLSI) technology, the cost of the equipment associated with a DSL deployment lowered significantly. Until the late 1990s, the cost of digital signal processors for DSL was prohibitive. Transmission methods vary by market, region, carrier, and equipment. Demand for high bandwidth applications, such as video and file sharing, also contributed to the popularity of ADSL technology. My BBW ex-girlfriend had the absolute best set of DSL 's that I've ever encountered. Click to see full answer People also ask, which DSL does gradle use? Other Resources: Acronym Finder has 65 verified definitions for DSL. According to Implementation and Applications of DSL Technology (2007), the PPPoE method far outweighed DHCP in terms of deployment on DSLs, and PAP was the predominant form of subscriber authentication used in such circumstances. 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. [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). 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. 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. What does DSL stand for? In symmetric digital subscriber line (SDSL) services, the downstream and upstream data rates are equal. This option (within the dashed bubble) often simplifies the connection. 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. Such deployment, even including equipment, is much cheaper than installing a new, high-bandwidth fiber-optic cable over the same route and distance. Along with cable Internet, DSL is one of the most popular ways ISPs provide broadband Internet access. Newer variants improved these rates. DSL stands for Digital Subscriber Line. Is this a good thing or a bad thing? Unlike traditional dial-up modems, which modulate bits into signals in the 300–3400 Hz audio baseband, DSL modems modulate frequencies from 4000 Hz to as high as 4 MHz. Possible DSL meaning as an acronym, abbreviation, shorthand or slang term vary from category to category. It started making a comeback in the United States in 2004 when Qwest started offering it, closely followed by Speakeasy. The accompanying figure is a schematic of a simple DSL connection (in blue). 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. 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 Single-lensmeans the camera uses the same lens for framing, focusing, and taking the photograph. Bit rates of 1 Gbit/s have been reached. But ADSL loop extenders increase these distances by repeating the signal, allowing the LEC to deliver DSL speeds to any distance.[8]. However, as long-distance trunks were gradually converted from analog to digital operation, the idea of being able to pass data through the local loop (by utilizing frequencies above the voiceband) took hold, ultimately leading to DSL. Loading coils are commonly set at regular intervals in POTS lines. Only one DSL modem can use the subscriber line at a time. Other Resources: Acronym Finder has 65 verified definitions for DSL. Distances greater than 2 km (1.2 mi) significantly reduce the bandwidth usable on the wires, thus reducing the data rate. A dry DSL line is also called a stand alone DSL line. With many service providers, the customer may opt for a modem which contains both a router and wireless access. Consumer-oriented ADSL was designed to operate on existing lines already conditioned for Basic Rate Interface ISDN services. However, these cables had other impairments besides Gaussian noise, preventing such rates from becoming practical in the field. What is DSL Internet Connection Meaning? Interleaved channel works better for file transfers, where the delivered data must be error-free but latency (time delay) incurred by the retransmission of error-containing packets is acceptable. 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. Internet Speeds for your needs â¢ 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. The left side shows the customer premises equipment with an optional router. What does DSL stand for? Tweet. A patent was filed in 1979 for the use of existing telephone wires for both telephones and data terminals that were connected to a remote computer via a digital data carrier system. of DSL subscribers jumps globally in 2003, China ranks top, DSL IC market rebounding, shifting to VDSL. 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. See other definitions of DSL. 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]. [7] This allowed Internet service providers to offer efficient service to consumers, who benefited greatly from the ability to download large amounts of data but rarely needed to upload comparable amounts. 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. Telephones are connected to the telephone exchange via a local loop, which is a physical pair of wires. Tweet. The subscriber's circuit is rewired to interface with hardware supplied by the ILEC which combines a DSL frequency and POTS signals on a single copper pair. 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. 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). The right side shows a DSLAM residing in the telephone company's telephone exchange. We know 375 definitions for DSL abbreviation or acronym in 8 categories. The earliest implementations used DHCP to provide network details such as the IP address to the subscriber equipment, with authentication via MAC address or an assigned host name. 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. At the exchange, a digital subscriber line access multiplexer (DSLAM) terminates the DSL circuits and aggregates them, where they are handed off to other networking transports. For dsl we have found 375 definitions. [1], In ADSL, the data throughput in the upstream direction (the direction to the service provider) is lower, hence the designation of asymmetric service. By 2012, some carriers in the United States reported that DSL remote terminals with fiber backhaul were replacing older ADSL systems.[9]. Instead, you need to rely on other methods for setting up the shot. DSL: [noun] acronym for "dick sucking lips." Stand out from the crowd. Top DSL acronym definition related to defence: Donât Stay Long All it means is that there is no dial tone or land line packaged or bundled on to the account. DSL stands for Digital Satellite Links. Texting DSL acronym meaning defined here. This converts data between the digital signals used by computers and the analog voltage signal of a suitable frequency range which is then applied to the phone line. All content on this website, including dictionary, thesaurus, literature, geography, and other reference data is for informational purposes only. filter out higher frequencies used for data. It builds connections through phone lines. In a bridged configuration, the group of subscriber computers effectively connect into a single subnet. The actual process varies from modem to modem but generally involves the following steps: Modern DSL gateways often integrate routing and other functionality. This is different from rangefinder and twin-lens-reflex constructions. What does DSL Stand For in Organizations, Education Schools etc. 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. Beach volleyball great under fire for not wearing mask It is a term used to describe a range of high-speed (broadband) communications services offered over the Public Switched Telephone Network (PSTN). Top DSL abbreviation related to Computer: Digital Subscriber Line Later implementations often use Point-to-Point Protocol (PPP) to authenticate with a user ID and password, and to provide network details (Point-to-Point Protocol over Ethernet (PPPoE) or Point-to-Point Protocol over ATM (PPPoA)). Digital subscriber line (DSL; originally digital subscriber loop) is a family of technologies that are used to transmit digital data over telephone lines. If supported, the DSL transceiver establishes a, The DSL transceiver establishes a connection with the router or computer. Please look for them carefully. First of all, what does DSLR stand for? Joseph W. Lechleider's contribution to DSL was his insight that an asymmetric arrangement offered more than double the bandwidth capacity of symmetric DSL. Digital subscriber line (DSL; originally digital subscriber loop) is a family of technologies that are used to transmit digital data over telephone lines. The key differences between DSL Internet, AT&T Internet and AT&T FiberSM is speed and what you can do with each of these. 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. Most DSL technologies require installation of appropriate filters to separate, or split, the DSL signal from the low-frequency voice signal. Stands for \"Digital Subscriber Line.\" DSL is a communications medium used to transfer digital signals over standard telephone lines. 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. DSL stands for desolé which, of course, means sorry. This means that internet providers are able to transmit digital dataâlike computer codeâover a phone line. The separation can take place either at the demarcation point, or with filters installed at the telephone outlets inside the customer premises. [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). [14] The system image can usually be updated to correct bugs, or to add new functionality. Because of this, phone companies endeavor to remove loading coils on copper loops that can operate without them. These advantages made ADSL a better proposition for customers requiring Internet access than metered dial up, while also allowing voice calls to be received at the same time as a data connection. This data is transmitted at a different frequency from a phone call, so, unlike dial-up, you â¦ Voice service cannot be maintained past a certain distance without such coils. What does DSL stand for? 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. ADSL â asymmetrical digital subscriber line â gives you more bandwidth for downloads than for uploads. You can down the image file in PNG format for offline use or send it to your friends by email. Furthermore, what does gradle stand for? what does DSL stand for. Technologies such as VDSL provide very high-speed but short-range links. There are a few types of internet, dial-up (uses a land-line) but is billed as a phone bill to access the internet. 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. 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. In some DSL variations (for example, HDSL), the terminal adapter connects directly to the computer via a serial interface, using protocols such as ethernet or V.35. Each way has its practical and economic limitations. 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. It stands for Digital Subscriber Line. 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. Employees at Bellcore (now Telcordia Technologies) developed asymmetric digital subscriber line (ADSL) by placing wide-band digital signals at frequencies above the existing baseband analog voice signal carried on conventional twisted pair cabling between telephone exchanges and customers. 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.
