<P>The asynchronous transfer mode (ATM) component contains networking support using ATM devices. There are four ATM communication modes:
<UL type="disc">
<LI>Using local area network (LAN) emulation, known as ATMLANE. This is the mode typically used in corporate LANs.</li>
<LI>Using Ethernet-permanent virtual circuit (PVC), known as ATMEPVC. This is used in certain ATM-DSL deployments.</li>
<LI>Using Classical Internet Protocols (IP) over ATM, known as ATMARPC and ATMARPS. This is an alternative LAN technique suitable for IP-only networks.</li>
<LI>Using Winsock over raw ATM connections. This is used for special purpose applications .</li>
</UL>
<H1>Component Configuration</H1>
<P>ATMLANE, ATMARPC, ATMARPS and Winsock do not require configuration when used over ATM.</P>
<P>The following table shows the settings for Ethernet-PVC configurations.</P>
