Chapter 5 Advanced Setup
This section contains advanced setup settings. To create a connection you need to define the
Layer 2 interface and the WAN service.
Configuration Types
VDSL is a PTM or ATM (ADSL fallback) based technology. The gateway supports Bridging and
Ethernet over ATM (EoA) configurations and ATM based configurations:
Bridging
Bridging (Layer 2 MAC addressing); uses Ethernet frames.
PPPoE
Point to Point Protocol over Ethernet; encapsulates PPP packet in Ethernet. (RFC 2516)
IPoE
IP over Ethernet (Layer 3 Internet Protocol addressing in Ethernet frames)
PPPoA
Point to Point Protocol over ATM, encapsulates PPP frames in ATM adaption layer 5 (AAL5)
packets.
IPoA
IP over ATM (Layer 3 Internet Protocol addressing in AAL5 packets
The table below describes the supported WAN interfaces and services supported on each interface.

To configure a connection, you first configure the connection type. EoA, PPPoA, or IPoA.
1. Add a Layer 2 interface and select the connection type.
EoA is used for PPPoE, IPoE and Bridge connections. PPPoA and IPoA are AAL5 based connections.
2. Set the WAN interface.
The WAN interface options to select are determined by the Layer 2 interface type.
