ATM VC
: ATM settings are used to connect to your ISP. Your ISP provides VPI (Virtual Path
Identifier), VCI (Virtual Channel Identifier) settings to you. In this Device, you can totally setup 8
VCs on different encapsulations, if you apply 8 different virtual circuits from your ISP. You need to
activate the VC to take effect. For PVCs management, you can use ATM QoS to setup each PVC
traffic priority.
Virtual Circuit: Select the VC number you want to setup, PVC0~PVC7.
Status: If you want to use a designed VC, you should activate it.
VPI: Identify the virtual path between endpoints in an ATM network. The valid range is from 0 to
255. Please input the value provided by your ISP.
VCI: Identify the virtual channel endpoints in an ATM network. The valid range is from 32 to
65535 (1 to 31 is reserved for well-known protocols). Please input the value provided by your ISP.
PVCs Summary: You can view the summary information about the PVCs.
QoS: Select the Quality of Service types for this Virtual Circuit, including CBR (Constant Bit Rate),
UBR (Unspecified Bit Rate) and VBR (Variable Bit Rate). These QoS types are all controlled by the
parameters specified below, including PCR (Peak Cell Rate), SCR (Sustained Cell Rate) and MBS
(Maximum Burst Size), please configure them according your needs.
Encapsulation: There are four connection types: Dynamic IP Address, Static Address,
PPPoA/PPPoE and Bridge Mode. Please choose the designed type that you want to use. After
that, you should follow the configuration below to proceed.
