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.
Configuration:
1. Start your browser and type 192.168.1.1 as the address to access ADSL web-based manager.
2. Go to Quick Start – Quick Setup. Uncheck Auto Scan Internet Connection (PVC). Key in the VCI
and VPI value, e.g.:
•
VPI – 8
•
VCI – 35
Click the Next button.
3. On the Configure Internet Connection – Connection Type page, select PPP over ATM (PPPoA)
then click the Next button.
4. On the WAN IP Settings page, select "Obtain an IP address" automatically and check Enable
NAT box. Click Next.
5. On the PPP Username and Password page, enter the PPP username and password that you
got from your ISP. Select "Always on" or select "Dial on Demand" and key in the inactivity
timeout value. (The default value is 20 minutes.) Then click "Next".
6. On the Configure LAN side Settings page, key in the IP address and subnet mask for your LAN,
e.g.:
Primary IP address: 192.168.1.1
Subnet Mask: 255.255.255.0
