DESCRIPTION

 

 

cell/sec

Divide the DSL line rate (bps) by 424 (the size of an ATM cell) to find the Peak Cell

 

Rate (PCR). This is the maximum rate at which the sender can send cells. Type the

 

PCR here.

Sustain Cell Rate

The Sustain Cell Rate (SCR) sets the average cell rate (long-term) that can be

 

transmitted. Type the SCR, which must be less than the PCR. Note that system

 

default is 0 cells/sec.

Maximum Burst

Maximum Burst Size (MBS) refers to the maximum number of cells that can be sent

Size

at the peak rate. Type the MBS, which is less than 65535.

for Internet access.

PPPoE

This feature is available only when you select PPPoE encapsulation.

Passthrough

In addition to the ZyXEL Device's built-in PPPoE client, you can enable PPPoE

 

Passthrough to allow up to ten hosts on the LAN to use PPPoE client software on

 

their computers to connect to the ISP via the ZyXEL Device. Each host can have a

 

separate account and a public WAN IP address.

 

PPPoE pass through is an alternative to NAT for applications where NAT is not

 

appropriate.

 

Disable PPPoE passthrough if you do not need to allow hosts on the LAN to use

 

PPPoE client software on their computers to connect to the ISP.
