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
