1740 SHDSL 2/4-Wire Router User’s Guide
3.2.4 PPPoA
When a VC is configured for PPPoA, the router will auto-detect the Authentication code (PAP or CHAP),
and the NAPT function will be enabled automatically.
STEP 1: Click WAN Setup on the Basic menu bar.
STEP 2: Enter values for the following fields: VPI, VCI, Encapsulation (LLC or VC MUX), Enable NAPT.
VPI Enter a value for the vitual path identifier
VCI Enter a value for the virtual channel identifier
LLC Encapsulation: With LLC encapsulation, a link control header is added to the
Ethernet packet that identifies the protocol type (Ethernet). This
allows multiple protocols to be transmitted over the ATM Virtual
Circuit.
VC Multiplexing: With VC Multiplexing, no link control header is needed as the
ATM Virtual Circuit is assumed to be carrying a single protocol.
Enable NAPT Selecting Enabling NAPT will enable Network Port Address
Translation on the WAN interface.
Keepalive Interval(sec): Keep-alive is a networking operation that periodically checks
the availability of a PPPoE/PPPoA connection between the CO
and CPE. If the keep-alive message is not acknowledged, the
connection will be interrupted.
STEP 3: Click PPPoA, and type the user name and password that the remote subscriber needs for
Internet access.
STEP 4: Click on the Add button. The new VC is added in the Current ATM PVC List on the bottom
screen.
