AccessRunner Ethernet/USB ADSL Modem
Device Set
Full-Rate and G.lite ADSL Modem Delivers High-Speed
Internet Connectivity
Conexant’s AccessRunner Ethernet/USB ADSL CPE solution is
optimized to address the growing demand for high-speed Internet
access. With both a USB 1.1-compliant interface and an IEEE
802.3-compliant Ethernet interface, it provides the widest array of
connectivity options without relying on host PC drivers. This ADSL
solution is not limited by host PC processor speed, operating
system or memory configuration. The AccessRunner device set is
fully compliant with the full-rate ADSL (T1.413 Issue 2 and G.dmt)
and the splitterless G.lite (G.992.2) standards. Compliance ensures
that products based on the AccessRunner solution can address the
existing installed base and continued deployment of ADSL lines.
Conexant’s AccessRunner modem is an “always-on” high-speed
broadband connection to the Internet. Using existing twisted pair
telephone lines, ADSL technology provides data rates more than
100 times as fast as a traditional dial-up modem delivers, without
an interruption in telephone service. With data transfer rates of up
to 8 Mbps downstream and 1 Mbps upstream, ADSL is the ideal
solution for high-bandwidth applications such as access to
a corporate network, Internet access and video delivery.
Conexant’s ADSL chipsets support the full range of ADSL
standards using industry-standard DMT line-code technology.
By automatically selecting the Ethernet or USB interface when the
appropriate cable is connected, the dual-interface Ethernet/USB
ADSL CPE chipset is a cost-effective, versatile solution that
supports all system environments.
Optimized Ethernet/USB ADSL Solution
The Ethernet/USB ADSL device set consists of an ADSL controller,
a DMT datapump, an AFE and a line driver. No host PC drivers
are required. All software and protocol stacks necessary for ADSL
are run in embedded firmware on the ADSL controller.
Web-based Management
All provisioning, configuration and management for the AccessRunner
Ethernet/USB modem device set is done via a Web browser. The
ADSL controller’s integrated Web server allows for user management
through a straight-forward and familiar interface. The Web server
is fully configurable, allowing OEMs to customize both
functionality
and appearance. The embedded file system implemented by
the ADSL controller simplifies Web server customization, and also
enables system upgrades via File Transfer Protocol (FTP).
ADSL Controller
Conexant’s P52 ADSL controller contains an integrated USB
1.1-compliant and IEEE 802.3-compliant Ethernet Media Access
Control (MAC) interface. The controller is a bridge between the
CX11627 DMT datapump and both of these host interfaces. It
provides the control, interface and a data manipulation for the
datapump, AFE and line driver. ATM SAR functions, as well as
encapsulation protocols (i.e., PPP over ATM, classical IP over
ATM, bridged/routed Ethernet over ATM, and PPP over Ethernet),
are performed by the ADSL controller.
DMT Datapump
The CX11627 DMT datapump is a T1.413 Issue- 2-G.992.1- and
G.992.2-compliant DSP. The device performs DMT modulation/
demodulation, ATM TC, FEC encoding/decoding, data
synchronization and data interleaving.
Analog Front End (AFE)
The CX20431 AFE is designed for use in full-rate and G.lite ADSL
modems. The receive path filters out unwanted echo and boosts
the wanted signal before performing an A/D conversion. The
Part Number DSAR-L100-501
