Huawei EchoLife HG520 User Manual page 33

There are 5 different connection modes under the WAN Settings:
I. PPPoA (PPP over ATM) and PPPoE
The configuration pages for these two modes are very similar,
with the only difference of choosing PPPoA or PPPoE for connecting
to the Internet.
When you are in the configuration page, enter the VPI/VCI
parameters and select the connection mode and encapsulation mode
to ensure your packet is transmitted in a more efficient rate. Single
click "submit" button to complete the settings. Go the Tool > Save &
Reboot to save the changes.
The configuration page is shown as Figure 4-6 when the
connection mode is PPP over ATM (PPPoA).
The configuration page is shown as Figure 4-7 when the
connection mode is PPP over Ethernet (PPPoE).
Generally speaking, the default connection and service modes
will satisfy your demand. However, you can configure settings based
on Internet Service Provider's request if there is such need.
You are free to skip the blank items on the configuration and
HG520 will use the factory default settings for operation. Take the
"Dial on demand, Inactivity Timeout" feature as example, if you do
not configure this item for the PCV under the PPPoA mode, the default
time would be 0. And if you set up the "Dial on demand, Inactivity
Timeout", the PVC will interrupt the Internet connection when you are
not using the Internet.
