Telephone lines primarily transmit analog voice signals, whereas ADSL (Asymmetric Digital Subscriber Line) uses the same twisted pair infrastructure to deliver high-speed digital data. ADSL separates voice and data signals through frequency division, allowing simultaneous use of telephone and internet services. This technology enables faster download speeds compared to upload speeds, catering to typical user behavior.

On what physical medium is an Asymmetric Digital Subscriber Line ADSL typically provisioned on?
Copper Telephone Line
How many Telephone use with oneADSL Modem?
The average home telephone system will support up to 13 ring tones. The ADSL modem shares the same line has the telephone. Each telephone to be connected to the same line as the ADSL requires a DSL filter. The telephone must be connected to the filter that is connected to the house telephone wiring. Therefore; it is possible to have a telephone in every room of the house and an ADSL always on connection at the same time. This would allow one to use the telephone and Internet at the same time.
What is the function of splitter?
Splitters typically have 3 labels: ADSL, Phone and Line. To use a splitter you connect your telephone devices (eg phone, fax or answering machine) to the connection labelled phone, your ADSL modem to the ADSL connection and the line to the wall socket. If you have other telephone wall sockets in the property on the same telephone line you will need to plug in filters between the phone and the wall socket.In addition to the user installable spliter in the photograph above, you can have a central splitter (see right) installed by a telephone technician. A central splitter is installed on the telephone line before the first phone point in the property. Thus the central splitter protects the all the phone exensions from the ADSL signal. A new phone point is wired into the central ADSL splitter specifically for the ADSL modem. The ADSL modem will not work on any other point in the property.Central Splitters are sometimes used when user installable splitters and filters do not result in a reliable ADSL connection
How does a dial up modem connect to the lnternet?
Telephone line. Either unplug telephone and connect lead to computer while online, or get double-socket ADSL connector so telephone is unaffected.
How does adsl divide bandwidth of a twisted pair cable?
ADSL (Asymmetric Digital Subscriber Line) divides the bandwidth of a twisted pair cable using frequency division multiplexing. It allocates lower frequencies for voice calls, allowing traditional telephone services to operate simultaneously with internet data. Higher frequencies are reserved for upstream and downstream data transmission, with downstream speeds typically being greater than upstream speeds, hence the term "asymmetric." This separation enables efficient use of the same line for both voice and data services without interference.
What is DSLAM?
Digital Service Line Access Multiplexer.It's the box in the exchange that connects between the telephone system and your Digital Subscriber Line (DSL), usually Asynchronous DSL (ADSL).
What does ADSL stand for in computer language?
Asymmetric Digital Subscriber Line(ADSL)
What is a term of ADSL?
ADSL stands for "Asynchronous (or Asymmetric) Digital Subscriber Line." It is a type of digital Internet communications carried over an analog line (POTS (Plain Old Telephone Service) or PTSN (Public Telephone Switched Network); they both refer to the same service). Typically, ADSL offers faster downstream communications and slower upstream communications, such as 8Mbit/1Mbit, which means the download speeds are eight times faster than the upload speeds (not including overhead and congestion).
Is adsl a wireless method?
No, ADSL (Asymmetric Digital Subscriber Line) is not a wireless method; it is a wired technology. ADSL transmits data over traditional copper telephone lines, allowing for high-speed internet access while still enabling voice calls on the same line. Wireless methods, on the other hand, use radio signals for data transmission, such as Wi-Fi or cellular networks.
Are microfilters and adsl filters the same thing?
Microfilters and ADSL filters serve a similar purpose but are not exactly the same. ADSL filters are specifically designed to separate voice and data signals on a single line, ensuring that ADSL internet service operates without interference from telephone calls. Microfilters, often used interchangeably with ADSL filters, can refer to smaller or more compact versions of these devices. In essence, while they perform the same function, "microfilter" may denote a specific type or size of ADSL filter.
What is an asymetric digital subscriber line?
Short for asymmetricdigitalsubscriberline, ADSL is a type ofDSL broadband communications technology used for connecting to the Internet. ADSL allows more data to be sent over existing copper telephone lines (POTS), when compared to traditional modem lines. A special filter, called a micro filter, is installed on a subscriber's telephone line to allow both ADSL and regular voice (telephone) services to be used at the same time. ADSL requires a special ADSL modem and subscribers must be in close geographical locations to the provider's central office to receive ADSL service. Typically this distance is within a radius of 2 to 2.5 miles. ADSL supports data rates of from 1.5 to 9 Mbps when receiving data (known as the downstream rate) and from 16 to 640 Kbps when sending data (known as the upstream rate).Asymmetric digital subscriber line (ADSL) is a type of digital subscriber line technology, a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide. It does this by utilizing frequencies that are not used by a voice telephone call.· A splitter, or DSL filter, allows a single telephone connection to be used for both ADSL service and voice calls at the same time.· ADSL can generally only be distributed over short distances from the telephone exchange, typically less than 4 kilometres (2 mi), but has been known to exceed 8 kilometres (5 mi) if the originally laid wire gauge allows for further distribution.At the telephone exchange the line generally terminates at a digital subscriber line access multiplexer(DSLAM) where another frequency splitter separates the voice band signal for the conventional phone network. Data carried by the ADSL are typically routed over the telephone company's data network and eventually reach a conventional Internet Protocol network.ADSL standardsVersionStandard nameCommon nameDownstream rateUpstream rateApproved inADSLANSI T1.413-1998 Issue 2ADSL8.0 Mbit/s1.0 Mbit/s1998ADSLITU G.992.1ADSL (G.DMT)12.0 Mbit/s1.3 Mbit/s1999-07ADSLITU G.992.1 Annex AADSL over POTS12.0 Mbit/s1.3 Mbit/s2001ADSLITU G.992.1 Annex BADSL over ISDN12.0 Mbit/s1.8 Mbit/s2005ADSLITU G.992.2ADSL Lite (G.Lite)1.5 Mbit/s0.5 Mbit/s1999-07ADSL2ITU G.992.3ADSL212.0 Mbit/s1.3 Mbit/s2002-07ADSL2ITU G.992.3 Annex JADSL212.0 Mbit/s3.5 Mbit/sADSL2ITU G.992.3 Annex LRE-ADSL25.0 Mbit/s0.8 Mbit/sADSL2ITU G.992.4splitterless ADSL21.5 Mbit/s0.5 Mbit/s2002-07ADSL2+ITU G.992.5ADSL2+24.0 Mbit/s1.3 Mbit/s2003-05ADSL2+ITU G.992.5 Annex MADSL2+M24.0 Mbit/s3.3 Mbit/s2008ADSL uses standard telephone lines to transmit upstream and downstream data on a digital frequency, which sets these datastreams apart from the analog signals telephones and fax machines use. Because the ADSL signal is operating on a different frequency, the telephone can be used normally, even when surfing the Web with ADSL service. The only requirement will probably be inexpensive DSL filters on each phone or fax line, to remove any "white noise" on the line that might be generated from ADSL service.
Which is faster. adsl or wimax?
ADSL - Uses typical twisted pair cable that come home. Maximum down stream (download) up to 8 Mbps. Divide the voice and data signals on the telephone line into three frequency bands.Wi-Max- Can go for over a much greater range. Point-to-multi point: last-mile Internet access. People can go up to 52 Mbps down stream (download) . Good solution for the people who can't get ADSL connection due to long distance.You see Faster connection is WI-MAX. But all the performances are depend on the packagers in the market.
