ADSL router with TI AR7 chip as central processor. The Texas Instruments AR7 or TI-AR7 is a fully integrated single-chip ADSL CPE access router solution. The AR7 combines a MIPS32 processor, a DSP-based digital transceiver, and an ADSL analog front end.
A DSL modem requires the following for its operation; exactly what is on the circuit card and how it is arranged can change as technology improves: Power supply; Data connection and power circuitry (for example, USB, Ethernet, PCI) DSL digital data pump; DSL analog chip and line driver; Microcontroller; Filter
Digital subscriber line (DSL; originally digital subscriber loop) is a family of technologies that are used to transmit digital data over telephone lines. [1] 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.
A standard phone line has enough room to support voice, high-speed DSL and a landline phone. [5] Two custom chips designed using the HPNA specifications were developed by Broadcom: the 4100 chip can send and receive signals over 1,000 ft (305 m) on a typical phone line. The larger 4210 controller chip strips away noise and passes data on.
Very high-speed digital subscriber line (VDSL) [1] and very high-speed digital subscriber line 2 (VDSL2) [2] are digital subscriber line (DSL) technologies providing data transmission faster than the earlier standards of asymmetric digital subscriber line (ADSL) G.992.1, G.992.3 (ADSL2) and G.992.5 (ADSL2+).
Furthermore, chips are often not available in order to implement the fastest rates. AMD, for instance, does not support the 32-bit HyperTransport interface on any CPU it has shipped as of the end of 2009. Additionally, WiMAX service providers in the US typically support only up to 4 Mbit/s as of the end of 2009.
High-bit-rate digital subscriber line (HDSL) is a telecommunications protocol standardized in 1994. [1] It was the first digital subscriber line (DSL) technology to use a higher frequency spectrum over copper, twisted pair cables.
A gateway is commonly used to make an ADSL connection. Asymmetric digital subscriber line (ADSL) is a type of digital subscriber line (DSL) technology, a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide.
