Description : AccessRunner™ ADSL-USB Modem Device Set View

Introduction

Overview

The Conexant AccessRunner ADSL-USB Modem Device Set combines an “always-on” high speed Asymmetric Digital Subscriber Line (ADSL) connection to the telephone line, and Universal Serial Bus (USB) connection to a host PC into a single cost-effective solution. Conexant’s AccessRunner ADSL Modem Device Set is compliant with the full-rate ANSI T1.413 Issue 2 and ITU G.dmt (G.992.1) ADSL standards, and with the splitterless ITU G.lite (G.992.2) specification. This rate-adaptive solution is designed for Customer Premise Equipment and supports downstream data rates of up to 8 Mbps and upstream data rates of up to 1 Mbps.

The Device Set takes advantage of the processing power available with today’s computers by eliminating the need for a separate ATM Segmentation and Reassembly (SAR) Device, resulting in a cost-effective solution suitable for both full rate and G.lite applications. Additionally, host-based software provides support for current industry standards for PPP over ATM (RFC 2364) and bridged Ethernet over ATM (RFC 1483) for Windows 98 and Windows 2000.

The USB specification version 1.1 is supported and is the preferred standard method to connect peripherals to PCs.

During periods of no data transmission, the Conexant ADSL DMT data pump performs idle cell insertion and deletion thus unloading this task from the host PC.

The Device Set consists of four Devices (see Figure 1-1 and Figure 1-2):



• USB Interface Controller (UIC), part no. P5200, in a 176-pin TQFP

• ADSL DMT Data Pump (ADDP), part no. CX11627, in a 176-pin TQFP

Description : PCI/USB ADSL CHIPSet: ST70138 + MTC20174 FOR ULTRA LOW COST ADSL Modem View

DESCRIPTION

The Unicorn II chipSet is designed to simplify the development of low-cost ADSL CPE Modems for Windows, Mac and Linux based environments and enables manufacturers to achieve a very competitive production cost. Due to its controller-less architecture and particularly the advantage that it does not require an external SDRAM in its E-BOM, the total cost of the external components needed in the Modem is the best in its class. With a low component count of less then 140 external components and small form factor packages, the Unicorn II easily fits on a standard 2 layer single sided PCB with small dimensions which contributes significantly to further lowering overall system costs. Together with its low power consumption, highspeed performance up to 8 Mbps and customizable complete software driver packages, the Unicorn II is the ideal choice for USB and PCI based ADSL Modems.



STANDARDS COMPLIANCE AND INTEROPERABILITY

Eleven years of experience have enabled ST to develop a chipSet that offers full compatibility with all current full-rate and G.lite ADSL standards, USB standards including plug-and-play support. The Unicorn II chipSet has a comprehensive driver suite that supports Windows, Mac and Linux. The Unicorn is fully interoperable with all major DSLAMs and is compliant to TR-048 (DSLforum) and ETSI 101 388 performance requirements.

STMicroelectronics
Description : ASCOT ADSL Modem CHIP Set FOR CPE View

GENERAL DESCRIPTION
The ADSL Modem chip Set with ATM interface provides all the active functions required to build a complete ATM-based ADSL Modem from line interface to ATM UTOPIA bus. The chip Set employs Discrete MultiTone modulation as specified in ANSI T1.413.
The chip Set operates at CPE end of the loop (ATU-R mode). Reed-Solomon forward error correction plus Trellis coding with or without interleaving in internal interleaving RAM provides maximum noise immunity (see Figure 3).
Interleaving is optional and can be used simultaneously on a slow channel (e.g., for data or control info) while a fast channel (e.g., video) operates without interleaving. ICs include rate adaptation capabilities during show time. In transmit direction the chip Set allows to select an attenuation of the signal in case of short loops or large echo (politeness). In receive direction the chip Set can optionally control an external multiplexer to select an external attenuation of the signal in case of short loops, and provide a 2-bit output external gain control.
