PPP over ATM (PPPoA) Mode
Description:
In this deployment environment, the PPPoA session is between the ADSL WAN interface and BRAS. The
ADSL Router gets a public IP address from BRAS when connecting to DSLAM. The multiple client PCs will get
private IP address from the DHCP server enabled on private LAN. The enabled NAT mechanism will translate
the IP information for clients to access the Internet.
