Chapter 1 Overview of the system

1.1 Introduction

The LDK24 including ADSL option card have an ADSL router functionality used for Internet/LAN access
via an ADSL line. LDK24 ADSL Router can run maximum upstream transmission rates of 640Kbps and
maximum downstream transmission rates of 8Mbps. The actual rate depends on the copper category of
your telephone wire, distance from the central office and the type of ADSL service subscribed to. See the
sections below for more background information on DSL and ADSL.

1.1.1 What is ADSL ?

It is an asymmetrical technology, meaning that the downstream data rate is much higher than the upstream
data rate. As mentioned, this works well for a typical Internet session in which more information is
downloaded, e.g., from Web servers, than is uploaded. ADSL operates in a frequency range that is above
the frequency range of voice services, so the two systems can operate over the same cable. What are the
advantages of ADSL from the point of view of the Network Service Provider (NSP) and the end user?
