Asymmetric digital subscriber lines (ADSL) transmit high bit rate data in the forward direction to the subscriber, and lower bit rate data in the reverse direction to the central office, both on a single copper telephone loop. In this paper I present a survey on the recent research and standardization of ADSL transceivers.
ADSL Line Driver/Receiver Design Guide, Part 1 - Analog
Central-office ADSL transceiver. Although there are several variations of DSL technology (SDSL, HDSL, HDSL2, VDSL and ADSL, to name a few) the requirements placed on the amplifiers for these different standards are very similar.

2021年10月26日 · 该系列建议书描述了金属双绞线上的非对称数字用户线(ADSL)收发器,允许其局端收发器单元(ATU-C)和用户端收发器单元(ATU-R)之间进行高速数据传输。 注意,这里所称的ADSL收发器就是我们日常所说的“ADSL调制解调器”或“ADSL猫”。 表1-3:ITU-T的G.992.x系列建议书的名称. 欲详细了解ITU-T的G.992.x系列建议书情况介绍的 请进入。 在我国,也编制了大量的相关ADSL技术的标准,包括国家标准和通信行业标准。 其中,ADSL的技 …
Lecture 18: ADSL Transceivers - University of Texas at Austin
Version 1.1 (May 24, 2006) implements a discretized, physical layer simulator for an ADSL2 system. The structure and default parameters of the transmitter, channel model, and receiver follow the ADSL2 ITU-T G.992.3 standard. A standalone executable demonstration that does not need a LabVIEW license is also available.

DMT-based ADSL: concept, architecture, and performance
2020年10月19日 · We present various aspects of a high performance ADSL transceiver system using the powerful discrete multitone (DMT) modulation technology. DMT is the adopted ADSL line code for the emerging North American (ANSI), …
AC7 ADSL Infrastructure Chipset The 16-port AC7 Infrastructure chipset from Texas Instruments (TI) supports all new ADSL standards and establishes a new baseline of integration that enables a much lower system cost—two key considerations for next-generation DSLAMs, IP-DSLAMs, mini-DSLAMs, and DLCs. The AC7 offers manufacturers
SACHEM, a versatile DMT-based modem transceiver for ADSL
1999年7月1日 · The complete digital processing (physical medium dependent) of the discrete multitone modulation scheme and transmission convergence layer has been integrated into a single device, processed in 0.35-mu m standard CMOS process. Power and area are kept well within limits, making this device a cost-effective solution for asymmetric digital subscriber line and network terminating systems. New ...
