ATM VC
•
Virtual Circuit:
VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier)
define a virtual circuit.
•
VPI
: The valid range for the VPI is 0 to 255. Enter the VPI assigned to you. This
field may already be configured.
•
VCI:

Select
VBR
for burst traffic and bandwidth sharing with other applications.
•
PCR:
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.
•
SCR:
The Sustain Cell Rate (SCR) sets the average cell rate (long-term) that can
be transmitted.
•
MBS:
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
Encapsulation:

Mode
field.
If you select
Bridge
in the

field in the previous screen.
•
Network Address Translation:
Select

,
Many to One
or
