In addition to works from the Spanish royal collection, other holdings increased and enriched the Museum with further masterpieces, such as the two Majas by Goya.

The identity of the Majas are uncertain.

Since one DSL termination point can support multiple ISPs, the economic feasibility of DSL is substantially improved.

Another way is IPTV, that is receiving TV via Internet Protocol, relying on Digital Subscriber Line ( DSL ) or optical cable line.

Design Science License ( DSL ) is a copyleft license for free content such as text, images, music and other content but not for documentation or source code.

Broadband is now available in Ireland via DSL, Cable, Wireless and Satellite.

As of November 2007, according to ComReg the Irish Communications Regulator DSL is available to c. 88 % of homes and businesses, however this figure is disputed my many pressure groups in Ireland as it only reflects the number of telephone lines connected to a broadband enabled exchange, not whether those lines are of a high enough quality to receive a DSL connection.

Since the principal consumer application is for Internet access, ISDN was mostly superseded by DSL in the early 21st century.

This is similar to the technique used by dialup modems as opposed to DSL modems.

IPTV ( over DSL ) is also planned by Romtelecom through its TV service ( Dolce ), after offering Satellite digital DTH TV.

ATM, a particularly popular form of cell relay, is most commonly used for home DSL connections, which often runs between 128 kbit / s and 1. 544 Mbit / s ( DS1 ), and for high-speed backbone connections ( OC-3 and faster ).

It is an umbrella term, used to cover multi-function networking appliances used in homes, which may combine a DSL modem or cable modem, a network switch, a consumer-grade router, and a wireless access point.

* It is also notable that the fully qualified domain name and the PTR record of DSL and cable lines connected to a residence will often contain ' cpe '.

Digital subscriber line ( DSL, originally digital subscriber loop ) is a family of technologies that provide internet access by transmitting digital data over the wires of a local telephone network.

In telecommunications marketing, the term DSL is widely understood to mean asymmetric digital subscriber line ( ADSL ), the most commonly installed DSL technology.

DSL service is delivered simultaneously with wired telephone service on the same telephone line.

This is possible because DSL uses higher frequency bands for data separated by filtering.

The underlying technology of transport across DSL facilities uses high-frequency sinusoidal carrier wave modulation, which is an analog signal transmission.

The DSL service provider's equipment is co-located in the same central office ( telephone exchange ) as that of the ILEC supplying the customer's pre-existing voice service.

The subscriber's circuit is then rewired to interface with hardware supplied by the ILEC which combines a DSL frequency and POTS frequency on a single copper pair facility.

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.

10 at least ( 2003 ), with most of them ADSL / DSL / Cable services.

* 5 connection levels: modem, DSL 512 kbit / s, ADSL 1024 kbit / s, ADSL 4096 kbit / s, DSL 15Mbit / s and VDSL 30 Mbit / s

Fiber Optic technologies exist today that allow the conversion of copper based ISDN, ADSL and DSL over fiber optics.

# Customer premises: DSL modem terminating the ADSL, SHDSL or VDSL circuit and providing LAN interface to single computer or LAN segment

Customers connect to the DSLAM through ADSL modems or DSL routers, which are connected to the PSTN network via typical unshielded twisted pair telephone lines.

Bell's digital subscriber line ( DSL ) services are based on ADSL, ADSL2 + and VDSL2 technology.

Naked DSL service is available in Switzerland from green. ch, origon ag ( oDSL ) and SETUP Informatik for ADSL and VDSL.

The presumption is that all these will have high speed connections to the network, delivered over copper ( in the form of ADSL or other DSL technologies ) or over fibre, as either PON or direct fibre in the case of large enterprises.

Similarly, multiple DSL lines can be bonded to give higher bandwidth ; in the United Kingdom, ADSL is sometimes bonded to give for example 512kbit / s upload bandwidth and 4 megabit / s download bandwidth, in areas that only have access to 2 megabit / s bandwidth.

DSL can be used as an access method for an ATM network, allowing a DSL termination point in a telephone central office to connect to many internet service providers across a wide-area ATM network.

In the United States, at least, this has allowed DSL providers to provide DSL access to the customers of many internet service providers.

: domestic: GTA: ~ 70, 000 local access lines, dial-up and DSL, Internet, long distance service, TDMA and GSM wireless services

Two encapsulated forms of PPP, Point-to-Point Protocol over Ethernet ( PPPoE ) and Point-to-Point Protocol over ATM ( PPPoA ), are used most commonly by Internet Service Providers ( ISPs ) to establish a Digital Subscriber Line ( DSL ) Internet service connection with customers.

They are not used when the service terminates in a modem, such as the DSL family of service.

Pursuant to recent FCC decisions, Internet DSL and Internet Cable services are now considered combined as one " information service.

Now, with no broadband telecommunications carrier service available, there are generally only two Internet broadband providers in a residential market: the cable Internet provider and the DSL Internet provider.

A DSL circuit provides digital service.

Unlike traditional dial-up modems, which modulate bits into signals in the 300 – 3400 Hz baseband ( voice service ), DSL modems modulate frequencies from 4000 Hz to as high as 4 MHz.

This frequency band separation enables DSL service and plain old telephone service ( POTS ) to coexist on the same copper pair facility.

Early DSL service required a dedicated dry loop, but when the U. S. Federal Communications Commission ( FCC ) required ILECs to lease their lines to competing DSL service providers, shared-line DSL became available.
