Field Description
Virtual Circuit
You can select a virtual circuit from the
drop-list. Click PVCs Summary you can view
eight PVCs (from PVC0 to PVC7), and only
PVC0 status is activated by default.
Status
You can select Activated or Deactivated for
currently selected virtual circuit.
VPI
The virtual path between two points in an
ATM network, ranging from 0 to 255.
VCI
The virtual channel between two points in an
ATM network, ranging from 1 to 65535.
ATM QoS Select the Quality of Service types for this
Virtual Circuit. The ATM QoS types include
CBR (Constant Bit Rate), VBR (Variable Bit
Rate) and UBR (Unspecified Bit Rate). These
QoS types are all controlled by the
parameters specified below, including PCR,
SCR and MBS. You can choose CBR, UBR,
rt-VBR or nrt-VBR.
PCR Peak cell rate (PCR) is the maximum rate at
which cells can be transmitted
along a
connection in the ATM network.
SCR Sustain cell rate (SCR) is the maximum rate
that traffic can pass over PVC without the risk
of cell loss.
MBS Maximum burst size (MBS) is the maximum
number of cells that can be transmitted at the
PCR.
ISP
You can choose Dynamic IP Address,
Static IP Address, PPPoA/PPPoE or
Bridge Mode.
