AT&T Internet

AT&T delivers most internet service over a fiber-to-the-node (FTTN) or fiber-to-the-premises (FTTP) communications network.

In the more common FTTN deployment, fiber-optic connections carry all data (internet, IPTV, and voice over IP) between the service provider and a distribution node.

In more recently constructed housing developments, AT&T uses an FTTP deployment—they run fiber-optic cable from their DSLAM all the way to an optical network terminal in the customer's home.

In areas where AT&T deploys internet through FTTN, they use High-speed digital subscriber lines with ADSL2+ or VDSL technology.

Service offerings depend on the customer's distance to an available port in the distribution node, or the central office.

In so-called "fringe" areas, AT&T provides High Speed Internet through IP-DSLAM ADSL2+, which does not require pair bonding or a VRAD and operates at slower bitrates than pair-bonded VDSL2.

In practice, VRADs are not installed in many older urban neighborhoods as AT&T prepares to abandon the fixed-line broadband market.

Conditions where higher speeds are still attainable through filters or quality wiring to more than one jack occur less often.

[11][12] AT&T Internet uses the Alcatel-Lucent 7330 or 7340 Intelligent Services Access Manager (ISAM) shelf, also called a video-ready access device (VRAD), deployed either in a central office (CO) or to a neighborhood serving area interface (SAI).

These models are both composed of circuit boards providing service, which are fed by fiber.

The fiber pairs typically lead to a customer's residence at the network interface device.

Those eligible for triple play (TV, Internet, and Phone) will use a VDSL2 transport link which uses one of the following modems: Along with the modems above, those eligible for fiber-to-the-home may have additional routers that could be used: Those who are eligible for double play (Internet and Phone) only, and aren't serviced by fiber-to-the-home, will use an ADSL2+ transport type which uses one of the following modems: Currently four devices support bonded pair: the 2Wire iNID, Arris NVG589 and NVG599, and Pace 5268AC.

AT&T allows residential and business customers to pay for static IP addresses, which they support on all AT&T approved equipment (including the 2Wire/Pace and Motorola routers).

Some users on GPON and XGS-PON have unofficially replaced AT&T's router by bridging 802.1X packets from one, extracting the 802.1X certificates from one and implanting them on a third-party router, or using a third-party ONT by "cloning" the AT&T-provided ONT with its serial number and MAC address to an aftermarket unit.

AT&T Worldnet, a dial-up Internet access service, was launched in 1996 to compete with AOL.

name:[citation needed] As of 2008, BellSouth Telecommunications (bellsouth.net) also provided AT&T FastAccess Internet service in the Southeastern United States.

In December 2006, the product launched in Chicago, San Francisco, Oakland, Hartford, Indianapolis, and other cities in their vicinities.

[26] In 2008, U-verse availability approached 8 million households and over 225,000 customers had been enrolled, with new installations reaching 12,000 per week.

The company began sending users notice of the change in Terms of Service on March 18, 2011.

AT&T Entertainment and Internet Services CEO John Stankey explained that the new platform would offer "single truck roll installation for multiple products, live local streaming, improved content portability, over-the-top integration for mobile broadband, and user interface re-engineering.

An AT&T spokesperson denied that U-verse was being shut down and explained that the company was "leading its video marketing approach with DirecTV" to "realize the many benefits" of the purchase, but would still recommend U-verse TV if it better-suited a customer's needs.

AT&T CFO John Stephens had also previously stated that DirecTV's larger subscriber base as a national service gave the service a higher degree of leverage in negotiating carriage deals, thus resulting in lower content costs.

[37][38] On May 16, 2016, AT&T acquired Quickplay Media, a cloud-based platform that powers over-the-top video services.

[51] It continues to sell its hybrid-fiber service, sold as “AT&T Internet,” which combines fiber trunk lines with DSL last-mile connections for faster speeds.

On January 30, 2008, AT&T announced that it would end a longtime partnership with Google for my.att.net and instead would begin to offer services provided by Yahoo!

On May 4, 2016, AT&T announced that it had entered into a new contract with Synacor for the company to take over the majority of its in-house internet services.
