Asymmetric DSL (ADSL) Line Card for Analog POTS
High speed Internet access with DSL technology
Digital subscriber line (DSL) technology is fast. Once users experience DSL
speeds, they do not want to go back to dialup access. DSL achieves broadband
speeds over ordinary phone lines.
With DSL, service providers can offer residential and business customers
access to high bandwidth information on demand, with improved opportunities to
experience streaming video, online gaming, multimedia applications, and
telecommuting.
Asymmetric DSL (ADSL), the most common form of DSL, delivers
multi-standards-based, high-speed DSL over a single copper pair, simultaneously
accommodating analog (voice) information and digital (data) information on the
same line.
The Alcatel ADSL solution for analog POTS
ADSL is the most widely deployed form of DSL technology. Most homes and small
businesses currently using DSL technology are connecting to the Internet with an
ADSL line.
Typically, ADSL generates downstream speeds of up to 8 megabits per second
(Mb/s) - 125 times faster than traditional 56.6 kilobits per second (kb/s)
analog modems - and generates upstream speeds of up to 800 kb/s.
Alcatel's ADSL solution for analog plain old telephone service (POTS) offers
providers mature ADSL equipment fully compliant with existing standards. Using
Alcatel's fourth generation DynaMiTe ADSL chip set, Alcatel offers a high
performance solution suitable for mass-market DSL deployment. Alcatel's solution
combines the density, low power consumption, and network management capabilities
providers need, with the ability to incrementally upgrade their systems while
maintaining their existing installed base.
Alcatel - A world leader in DSL solutions
With the largest installed base of DSL lines in the world, Alcatel knows what it
takes to help providers succeed. And Alcatel delivers it. Alcatel has a full
range of DSL solutions for both home and business use.
Alcatel offers a cost-effective, flexible architecture that easily scales to
meet the demands of a large-scale DSL services rollout. Alcatel takes an
end-to-end systems approach to DSL, with proven solutions. Alcatel's DSL
solutions allow for the introduction of new network services with a competitive
edge.
