Encapsulation Select the method of encapsulation used by your ISP from the drop-
down list box. Choices vary depending on the mode you select in the
Mode field.
PPPoA - Point-to-Point Protocol over ATM (PPPoA) encapsulates PPP
frames inside ATM Adaptation Layer 5 frames. PPPoA is a similar
specification to PPPoE and is used for for connecting users on an local
network connection (such as from a computer to a routing device) to
the Internet through a common broadband medium, such as a single
DSL line or wireless device. However, this specification has slightly
lower overhead than PPPoE as it has 2 less transport layers.
RFC 1483 - Multiprotocol Encapsulation over ATM Adaptation Layer 5
allows an ATM virtual circuit to mimic the properties of an Ethernet IP
LAN, connecting the two either through bridging or routing.
ENET ENCAP - The MAC Encapsulated Routing Link Protocol (ENET
ENCAP) is only implemented with the IP network protocol. IP packets
are routed between the Ethernet interface and the WAN interface and
then formatted so that they can be understood in a bridged
environment. For instanced, it encapsulated routed Ethernet frames
into bridged ATM cells.
PPPoE - Point-to-Point Protocol over Ethernet (PPPoE) encapsulates
PPP frames inside Ethernet frames. PPPoE is a similar specification to
PPPoA for connecting users on an local network connection (such as
from a computer to a routing device) to the Internet through a
common broadband medium, such as a single DSL line or wireless
device. However, this specification has slightly higher overhead than
PPPoA as it has 2 more transport layers.
User Name (PPPoA and PPPoE encapsulation only.)
Enter the user name exactly as your ISP assigned. If assigned a name
in the form user@domain where domain identifies a service name,
then enter both components exactly as given.
Password (PPPoA and PPPoE encapsulation only.)
Enter the password associated with the user name above.
Service Name (PPPoE only.)
Type the name of your PPPoE service here.
Multiplex Select the method of multiplexing used by your ISP from the drop-
down list. Choices are VC or LLC.
This field is not available if you set the WAN type to Ethernet.
Virtual Circuit ID VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier) define
a virtual circuit. Refer to the appendix for more information.
These fields are not available if you set the WAN type to Ethernet.
VPI The valid range for the VPI is 0 to 255. Enter the VPI assigned to you.
VCI The valid range for the VCI is 32 to 65535 (0 to 31 is reserved for
local management of ATM traffic). Enter the VCI assigned to you.
