xvi Preface

Preface

Congratulations on your purchase from the VES-1000 Series of VDSL-Ethernet Switches.

This preface introduces you to the VES-1000 Series and discusses the organization and conventions of this User’s

Guide. It also provides information on other related documentation.

About VDSL

VDSL (Very high bit rate Digital Subscriber Line) is one type of DSL with very high data rates. The service can

be asymmetrical or symmetrical and can be used on the same wire as the POTS (Plain Old Telephone Service)

network and ISDN.

About the VES-1000 Series

The VES-1000 Series of VDSL-Ethernet Switches delivers high-performance broadband access at low cost to

multi-tenant unit (MTU) buildings (hotels, motels, resorts, residential multi-dwelling units, office buildings,

university campuses, etc.) and public facilities, such as convention centers, airports, plazas, and train stations. It

attains speeds ranging from 1.56 Mbps to 16.67 Mbps upstream and 4.17 Mbps to 16.67 Mbps downstream at

distances of up to 1.5 Km (5,000 feet) delivered over ordinary telephone lines.

VES-1000 Series Models

There are currently two models in the VES-1000 Series of Ethernet Switches. All models can be mounted on a

wall or placed on a rack. They have built-in voice-signal splitters for added system stability. In addition to remote

management capability, a console port is used for local management. They are equipped with VLAN (Virtual

LAN) capability that can isolate each port. Please see the appendices for more detailed hardware specifications.

General Syntax Conventions

This guide shows you how to configure both models using the SMT menus and CLI commands. See the online

HTML help for information on how to use the web configurator to configure both models.

“Enter” means for you to type one or more characters and press the carriage return. “Select” or “Choose” means

for you to select one from the predefined choices.

The SMT menu titles and labels are in Bold Times New Roman font. Predefined field choices are in Bold Arial

font. Command and arrow keys are enclosed in square brackets. [ENTER] means the Enter, or carriage return

key; [ESC] means the Escape key and [SPACE BAR] means the Space Bar.

For brevity’s sake, we will use “e.g.” as shorthand for “for instance”, and “i.e.” as shorthand for “that is” or “in

other words” throughout this manual.
