ATM VC
Virtual Circuit:
VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier) define a
virtual circuit.
PVC Summary:
VPI
:
The valid range for the VPI is 0 to 255. Enter the VPI assigned to you. This field may
already be configured.
VCI:
The valid range for the VCI is 32 to 65535. Enter the VCI assigned to you. This field
may already be configured.
ATM QoS:
Select
CBR
to specify fixed (always-on) bandwidth for voice or data traffic.
Select
UBR
for applications that are non-time sensitive, such as e-mail. 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
ISP:
Select the encapsulation type your ISP uses from the
Encapsulation
list.
Choices vary depending on what you select in the
Mode
field.
Dynamic IP:
Select this option if your ISP provides you an IP address automatically.
This option is typically used for Cable services. Please enter the Dynamic IP information
accordingly.
Static IP
:
Select this option to set static IP information. You will need to enter in the
Connection type, IP address, subnet mask, and gateway address provided to you by
