of DSL subscribers jumps globally in 2003, China ranks top, DSL IC market rebounding, shifting to VDSL. This is true both for ADSL and SDSL variations. 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. [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). [14] The system image can usually be updated to correct bugs, or to add new functionality. This option (within the dashed bubble) often simplifies the connection. Abbreviation Database Surfer.

Tweet. 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. Their initialization is very similar to a PC boot up. Possible DSL meaning as an acronym, abbreviation, shorthand or slang term vary from category to category. 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. Most DSL technologies require installation of appropriate filters to separate, or split, the DSL signal from the low-frequency voice signal. 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 DSL transceiver performs a self-test, including image load and activation. We know 375 definitions for DSL abbreviation or acronym in 8 categories. 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. Therefore, some areas that are within range for DSL service are disqualified from eligibility because of loading coil placement. Advertisement: This definition appears somewhat frequently. See other definitions of DSL. DSL, which does the same thing except phone companies process the information differently. DSL stands for digital subscriber line. Joseph W. Lechleider's contribution to DSL was his insight that an asymmetric arrangement offered more than double the bandwidth capacity of symmetric DSL. The left side shows the customer premises equipment with an optional router. But ADSL loop extenders increase these distances by repeating the signal, allowing the LEC to deliver DSL speeds to any distance.[8]. • Our 100% fiber network enables the fastest Broadband speeds that AT&T delivers. [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. 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. Newer variants improved these rates. With those types, you can’t see the view from the lens that will take the shot. There are a few types of internet, dial-up (uses a land-line) but is billed as a phone bill to access the internet. Telephones are connected to the telephone exchange via a local loop, which is a physical pair of wires. But yes, that is what DSL stands for. Instead, you need to rely on other methods for setting up the shot. The lowest band allows for telephone calls, while the other two bands take care of uploading and downloading online activity. 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)). What is DSL Internet Connection Meaning? What does DSL filter do. The underlying technology of transport across DSL facilities uses modulation of high-frequency carrier waves, an analog signal transmission. In this case, the equipment is referred to as a gateway. DSL stands for "digital subscriber line." Bringing you to the front of the stage. 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. 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. Your girlfriend has some great goddamn DSL . What does DSL stand for in Texting? Which basically means a telephone line, that has a signal superimosed on it, by a service provider, to enable a broadband internet connection. ADSL – asymmetrical digital subscriber line – gives you more bandwidth for downloads than for uploads. Distances greater than 2 km (1.2 mi) significantly reduce the bandwidth usable on the wires, thus reducing the data rate. What does DSL stand for? DSL Stands For: All acronyms (375) Airports & Locations (3) Business & Finance (11) Common (4) Government & Military … This segregation reduces interference. DSL stands for desolé which, of course, means sorry. The local loop was originally intended mostly for the transmission of speech, encompassing an audio frequency range of 300 to 3400 hertz (commercial bandwidth). Bit rates of 1 Gbit/s have been reached. Demand for high bandwidth applications, such as video and file sharing, also contributed to the popularity of ADSL technology. ADSL supports two modes of transport: fast channel and interleaved channel. In symmetric digital subscriber line (SDSL) services, the downstream and upstream data rates are equal. What does DSL Stand For in Organizations, Education Schools etc. DSL implementations may create bridged or routed networks. Cable, which uses TV … Cable companies provide a cable modem fo… 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. With many service providers, the customer may opt for a modem which contains both a router and wireless access. Until the late 1990s, the cost of digital signal processors for DSL was prohibitive. Thus POTS-based communications, including fax machines and dial-up modems, can share the wires with DSL. DSLR is the abbreviation for Digital Single Lens Reflex. Top DSL acronym definition related to defence: Don’t Stay Long what does DSL stand for. It stands for Digital Subscriber Line. The company was founded in the United States in 1969 and expanded its service throughout the world by the late 1970s. Computer DSL abbreviation meaning defined here. 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. Transmission methods vary by market, region, carrier, and equipment. Furthermore, what does gradle stand for? 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. showing only Slang/Internet Slang definitions ( show all 65 definitions) Note: We have 250 other definitions for DSL in our Acronym Attic. Can both a phone and PC be used simultaneously on ADSL. 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). Please look for them carefully. Because of this, phone companies endeavor to remove loading coils on copper loops that can operate without them. 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. Consumer-oriented ADSL was designed to operate on existing lines already conditioned for Basic Rate Interface ISDN services. Longer lines that require them can be replaced with fiber to the neighborhood or node (FTTN). DSL stands for Digital Subscriber Line. 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). 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. Signals received from the far-end modem are demodulated to yield a corresponding bit pattern that the modem passes on, in digital form, to its interfaced equipment, such as a computer, router, switch, etc. The following image presents the most commonly used meanings 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. ?. ; What does DSL mean? ; What does DSL mean? DSL offers a diverse range of features across the entire series including power reduction, studio quality reverb and two footswitchable channels. What does DSL stand for? Technologies such as VDSL provide very high-speed but short-range links. Stands for \"Digital Subscriber Line.\" DSL is a communications medium used to transfer digital signals over standard telephone lines. Depending on the length and quality of the loop, the upper limit can be tens of megahertz. Search for DSL in Online Dictionary Encyclopedia. Voice service cannot be maintained past a certain distance without such coils. See other definitions of DSL. Digitalmeans that the camera operates with a fixed, digital sensor. The company delivers over 1.3 billion parcels per year. Along with cable Internet, DSL is one of the most popular ways ISPs provide broadband Internet access. Possible DSL meaning as an acronym, abbreviation, shorthand or slang term vary from category to category. If supported, the DSL transceiver establishes a, The DSL transceiver establishes a connection with the router or computer. More usable channels equate to more available bandwidth, which is why distance and line quality are a factor (the higher frequencies used by DSL travel only short distances). [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). Each way has its practical and economic limitations. Most homes and small business users are connected to an asymmetric DSL (ADSL) 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. 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.. One such circuit in the United Kingdom ran some 10 miles (16 km) between the BBC studios in Newcastle-upon-Tyne and the Pontop Pike transmitting station. This is different from rangefinder and twin-lens-reflex constructions. https://acronyms.thefreedictionary.com/DSL, Against the backdrop of soaring demand for, Customers who subscribe to any FastAccess, "BPL can certainly provide an avenue for a number of folks who haven't adopted broadband yet because it's at a slightly lower cost than say, While 100 Mbp/s ultra-broadband access can be made available relatively quickly by utilizing legacy copper-line resources, using, "There are a number of drivers and challenges for, Dictionary, Encyclopedia and Thesaurus - The Free Dictionary, the webmaster's page for free fun content, MRRSE-DSL Tester Market: Vendors Announce Product Upgrades and Roll out Economically Viable High-performance Equipment, BELLSOUTH REDUCES COST OF FASTACCESS DSL INTERNET SERVICE, Incremental 2-D Nearest-Point Search with Evenly Populated Strips, Reshaping the telecom landscape: COMTek executive delivers new broadband option, OP-ED: Court: public need required for wetland and waterway fill permits, ALLIANCE CREATES SOLUTIONS FOR FINANCIAL INSTITUTIONS, Global DSL and G-fast Chips Market to Show Exponential Growth Thanks to Usage of Existing Copper Infrastructure - by MRRSE, No. This means that internet providers are able to transmit digital data—like computer code—over a phone line. new search. It works because the DSL system separates the telephone signals into three bands of frequencies. DSL stands for Dual Super Lead. 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. The key differences between DSL Internet, AT&T Internet and AT&T FiberSM is speed and what you can do with each of these. 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. 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. 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. Dumb Stupid Loser. In the 1950s, ordinary twisted-pair telephone cable often carried four megahertz (MHz) television signals between studios, suggesting that such lines would allow transmitting many megabits per second. The DSLAM terminates all connections and recovers the original digital information. The 1980s saw the development of techniques for broadband communications that allowed the limit to be greatly extended.

We know 375 definitions for DSL abbreviation or acronym in 8 categories. 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. The right side shows a DSLAM residing in the telephone company's telephone exchange. yes. Digital subscriber line (DSL; originally digital subscriber loop) is a family of technologies that are used to transmit digital data over telephone lines. 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.

The actual process varies from modem to modem but generally involves the following steps: Modern DSL gateways often integrate routing and other functionality. Is this a good thing or a bad thing? suggest new definition. Other Resources: Acronym Finder has 65 verified definitions for DSL. 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. 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. 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]. 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. Such deployment, even including equipment, is much cheaper than installing a new, high-bandwidth fiber-optic cable over the same route and distance.
