Because I can't be the only one trying to configure the EDIMAX DSL Modem Router to work with Bellsouth FastAccess ADSL, here is the configuration I finally found that works. Note that the following is a list of things that you need to change from the default configuration:
Virtual Circuit: Enabled
Bridge: Disabled
IGMP: Disabled
Encapsulation: PPPoE LLC
VPI: 8
VCI: 35
Service Category: UBR
DHCP: Disabled
MAC Spoofing: Disabled
Advanced ADSL Configuration

Handshake Protocol: G.dmt
