Parameter Description
Encapsulation
Shows the packet encapsulation type.
Packet encapsulation specifies how to handle multiple protocols at
the ATM transport layer.
•
VC-MUX: Point-to-Point Protocol over ATM Virtual Circuit
Multiplexer (null encapsulation) allows only one protocol running
per virtual circuit with less overhead.
•
LLC: Point-to-Point Protocol over ATM Logical Link Control allows
multiple protocols running over one virtual circuit (using slightly
more overhead).
QoS Class
ATM QoS classes including CBR, UBR and VBR.
PCR/SCR/MBS
QoS Parameters - PCR (Peak Cell Rate), SCR (Sustainable Cell Rate)
and MBS (Maximum Burst Size) are configurable.
IP Address:
If your IP address is assigned by the ISP each time you
connect, leave this field all zeros. Otherwise, enter your ISP supplied
static IP address here.
Subnet Mask:
If your subnet mask is assigned by the ISP each time
you connect, leave this field all zeros. Otherwise, enter your subnet
mask here.
Connect Type
Sets connection mode to always connected, automatic or manual
connection.
Idle Time: Enter the maximum idle time for the Internet connection.
(in minutes) After this time has been exceeded the connection will be
terminated.
Username:
Enter user name
Password:
Enter password
Confirm Password:
Confirm password
MTU
Leave the Maximum Transmission Unit (MTU) at the default value
(1500) unless you have a particular reason to change it.
Parameter Description
Protocol
•
Disable:
Disables the connection.
•
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.
