Chapter 1: Introduction

The switch provides a broad range of features for Layer 2 switching. It includes a management agent that allows you to configure the features listed in this manual. The default configuration can be used for most of the features provided by this switch. However, there are many options that you should configure to maximize the switch’s performance for your particular network environment.

The switch uses four frequency bands (two downstream and two upstream) for VDSL lines. These frequency bands conform to ANSI Plan 998. Details of the frequency bands are given in the table below.
