Peak Cell Rate

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.This field is not available when you 
select UBR Without PCR.

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. 

This field is available only when you select Non Realtime VBR or 
Realtime VBR.

Maximum Burst 
Size

Maximum Burst Size (MBS) refers to the maximum number of cells that 
can be sent at the peak rate. Type the MBS, which is less than 65535.

This field is available only when you select Non Realtime VBR or 
Realtime VBR.

VLAN (These fields appear when the Type is set to VDSL or Ethernet)
Active

Select this option to add the VLAN tag (specified below) to the outgoing 
traffic through this connection.

802.1P 

IEEE 802.1p defines up to 8 separate traffic types by inserting a tag 
into a MAC-layer frame that contains bits to define class of service. 

Select the IEEE 802.1p priority level (from 0 to 7) to add to traffic 
through this connection. The greater the number, the higher the 
priority level.

802.1Q

Type the VLAN ID number (from 1 to 4094) for traffic through this
