Advanced Setup Method
• LLC: Point-to-Point Protocol over ATM Logical Link Control
(LLC) allows multiple protocols running over one virtual circuit
(using slightly more overhead).
Protocol: Protocol used for the connection
ATM Interface
Clicking on the ATM VC brings up the following screen. The VoIP
Router uses ATM as its WAN interface. Protocols including 1483
Routing, 1483 Bridging, MAC Encapsulated Routing (MER), PPPoA
and PPPoE with LLC-SNAP and VC-MUX encapsulations are
supported for each ATM PVC.
When you have finished entering your connection parameters, click
"SAVE SETTINGS". You can verify that you have established an ADSL
connection by clicking Status at the bottom of the left-hand menu.
See below for a description of the parameters.

• 1483 Bridging: Bridging is a standardized layer 2 technology. It
is typically used in corporate networks to extend the physical
reach of a single LAN segment and increase the number of
stations on a LAN without compromising performance. Bridged
data is encapsulated using the RFC1483 protocol to enable
data transport. Please note that setting the router to bridged
mode disables all advanced features such as VoIP, Firewall, and
QoS etc
• PPPoA: Point-to-Point Protocol over ATM is a method of
encapsulating data for transmission to a far point
1483 Routing: 1483 Routing allows a simple, low-cost
•
connection to the Internet via a standard Ethernet port. The
router looks up the network address for each packet seen on
the LAN port. If the address is listed in the routing table as
local, it is filtered. If the address is listed under the ADSL port,
it is forwarded. Or if the address is not found, then it is
automatically forwarded to the default router (i.e., the VoIP
Router at the head end)
• PPPoE: Point-to-Point over Ethernet is a common connection
method used for xDSL
• MAC Encapsulated Routing: If your ADSL service is a Bridged
mode service and you want to share the connection to multiple
PC's, please select MAC Encapsulated Routing. MER is a
protocol that allows you do IP routing with NAT enabled
VPI/VCI
Virtual Path Identifier (VPI) and Virtual Circuit Identifier (VCI). Data
flows are broken up into fixed length cells, each of which contains a
Virtual Path Identifier (VPI) that identifies the path between two nodes,
and a Virtual Circuit Identifier (VCI) that identifies the data channel
within that virtual path. Each virtual circuit maintains a constant
flow of cells between the two end points. When there is no data to
transmit, empty cells are sent. When data needs to be transmitted, it
is immediately inserted into the cell flows.
