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.
