非对称数字用户线路（ADSL，Asymmetric Digital Subscriber Line）是数字用户线路（xDSL，Digital Subscriber Line）服务中最流行的一种。ADSL的国际标准于1999年获得批准，称为 G.dmt。它允许高达8 Mbps的下行速度和 1 Mbps的上行速度。
What is ADSL (Asymmetric Digital Subscriber Line)? - TechTarget
ADSL (Asymmetric Digital Subscriber Line) is a technology that facilitates fast data transmission at a high bandwidth on existing copper wire telephone lines to homes and businesses. Unlike regular dial-up copper telephone line service, ADSL provides continuously available, always-on broadband connections.
ADSL - 维基百科，自由的百科全书
ADSL是一種資料通訊技術，利用既存的電話線（銅線）提供比語音頻帶數據機（英語： Voiceband Modem ）更高的傳輸速度。ADSL有別於與較不普及的SDSL，頻寬和位元率並不是對稱的，也就是說下行的速度高於上行的速度。供應商通常將ADSL視為一種網際網路存取服務 ...
ADSL Line Driver/Receiver Design Guide, Part 1 - Analog
2000年2月1日 — Consumer desire for faster Internet access is driving the demand for very high data rate modems. A digital subscriber line (DSL) implementation speeds data to and from remote servers with data rates of 512Kbps to 8Mbps, much …
ADSL - Wikipedia
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. ADSL differs from the less common symmetric digital subscriber line (SDSL).
Introduction to Asymmetric Digital Subscriber Line (ADSL)
2023年5月7日 — Asymmetric Digital Subscriber Line (ADSL) is a technology that allows high-speed digital data transmission over existing copper telephone lines. It is called “asymmetric” because it provides higher download speeds than upload speeds, which is suitable for applications such as web browsing, email, and streaming video.
What is ADSL? definition & meaning - Technipages
ADSL is the acronym for Asymmetric Digital Subscriber Line, and they are used to enact data transmission at high speed to the internet. Invented by AT&T and adopted by ANSI as standard T1.413 in 1995. Like all DSL broadband technologies, enables a standard telephone line (copper twisted-pair) to simultaneously carry voice and data.
Asymmetric Digital Subscriber Line (ADSL):Connectivity Wonders …
2024年3月15日 — Asymmetric Digital Subscriber Line (ADSL) is a high-speed technology delivering video and voice over copper telephone wires. This article explores the intricacies of ADSL, its competition with cable modems, bandwidth comparisons, and its advantages in widespread availability.
What is ADSL? | Webopedia
2021年5月24日 — Asymmetric digital subscriber line (ADSL) is a type of DSL broadband communications technology used for connecting to the Internet. ADSL allows more data to be sent over existing copper telephone lines (POTS), when compared to traditional modem lines.
ADSL Technology Explained, Part 1: The Physical Layer
2001年3月1日 — We begin our tour of the ADSL system architecture with a look at the physical layer (PHY). Topics covered at the PHY will include ADSL's multicarrier modulation technique, common impairments, and phone-line characteristics. Spectrum allocation. The ADSL PHY was designed so that it could peacefully co-exist with the standard POTS spectrum.
