Enter the Virtual Channel Identifier(s) (VCI) given.

 

 

 

 

 

 

Static IP Address

This is the static IP provided by your ISP.

 

 

 

 

 

 

Subnet Mask

This is the corresponding subnet mask for the above IP address.

 

 

 

 

 

 

Gateway

This is the gateway IP address.

 

 

 

 

 

 

ATM

 

 

 

 

 

 

 

Service Category

Select the service category (UBR or CBR).

 

 

 

 

 

 

Bandwidth

Bandwidth setting takes effect only when the CBR is selected. Enter a bandwidth

 

 

 

in kbps.

 

 

 

 

 

 

Encapsulation

Choose an encapsulation type. The choices are as follows: PPPoA VC-MUX,

 

 

 

PPPoA LLC, 1483 Bridged IP LLC, 1483 Routed IP LLC, 1483 Bridged IP

 

 

 

VC-Mux, 1483 Routed IP VC-Mux,Classical IP over ATM, PPPoE VC-Mux,

 

 

 

PPPoE LLC, and PPPoE None.

MRU

The Maximum Receive Unit (MRU) indicates the maximum size of the PPP

 

 

 

information field that this device can receive. The default value is 1492 and is

 

 

 

used in the beginning of the PPP negotiation. During negotiation, the peer will

 

 

 

accept this MRU and will not send packets with information fields larger than this

 

 

 

value.

 

 

 

 

 

 

MTU

If the network stack of any packet is larger than the Maximum Transmission Unit

 

 

 

(MTU), it will be fragmented before transmission. During PPP negotiation, the

 

 

 

peer of the PPP connection will indicate its MRU. The actual MTU of the PPP

 

 

 

connection will be set to either the MTU or the peer’s MRU (whichever is

 

 

 

smaller). The default is value 1492.

 

 

 

 

 

 

MSS

The Maximum Segment Size (MSS) is the largest size of data that TCP will send

 

 

 

in a single IP packet. When a connection is established between a LAN client

 

 

 

and a host on the WAN side, the LAN client and the WAN host will indicate their

 

 

 

MSS during the TCP connection handshake. The default value is 1432.
