VDSL is deployed over existing wiring used for analog telephone service and lower-speed DSL connections. This standard was approved by the International Telecommunication Union (ITU) in November 2001.

This is a list of very-high-bit-rate digital subscriber line (VDSL) and very-high-bit-rate digital subscriber line 2 (VDSL2) deployments.

VDSL: Very-High-Bit-Rate DSL Also approved in 2001, VDSL as a DSL service enables downstream/upstream rates up to 52 Mbps/16 Mbps. Extenders for local networks boast 100-Mbps/60-Mbps speeds when communicating at distances up to 500 feet (152.4 m) over a single voice-grade twisted pair.

ADSL (Asymmetric Digital Subscriber Line) and VDSL (Very High Bitrate Digital Subscriber Line) mainly differ in the speed of data transmission or data rate, where VDSL is significantly faster than ADSL.

VDSL technology, both MSM and SCM, is flexible and could be adopted to a wide variety of deployment scenarios. Most of parameters are programmable. The following ITU agreements specify transport of data packets:

Apr 25, 2022 · The main technical characteristics of the established VDSL connection are shown in the parameters 'Standard', 'Speed', 'Noise margin', 'Signal power level', and 'Signal attenuation'. The VDSL2 uses the same parameters as ADSL2+ technology.

Mar 18, 2016 · 1. What is VDSL/VDSL2? VDSL, or Very-High-Bit-Rate Digital Subscriber line, allows Internet Service Providers to provide fast connection speeds via legacy copper lines. VDSL and VDSL2 can provide faster broadband performance when compared to ADSL/2+ up to approximately 1.5km distances.

May 9, 2016 · This document describes how to configure your Cisco Digital Subscriber Line (DSL) Customer Premise Equipment (CPE) Router for Very High Bit Rate Digital Subscriber Line (VDSL) service. It explains how to troubleshoot VDSL related issues on the Cisco 880 Series, 890 Series, 860 Series, and VDSL/ Asynchronous Digital Subscriber Line (ADSL ...

To aid in the evaluation of VDSL solutions, this paper discusses important technical constraints of the VDSL transmission environment, summarizes key ANSI and ETSI requirements for VDSL systems, and considers popular line code and duplexing schemes in respect to these factors. 3 VDSL fundamentals

Aug 15, 2024 · The show controller vdsl 0/0/0 command is used to display all DSL [VDSL2/ADSL2/ADSL2+] controller information, like the C111x platforms. Although the controller command is VDSL, it actually means DSL and is used for ADSL and VDSL alike. Using the WebUI, interface g0/0/0 can be configured/monitored as normal.
