2-6 Firmware User Guide
• Enter a name for the circuit in the Circuit Name field.
• Toggle Circuit Enabled to Yes.
• Enter the Virtual Path Identifier and the Virtual Channel Identifier in the Circuit VPI and Circuit VCI
fields, respectively.
• The Peak Cell Rate field is editable. Netopia Firmware Version 8.4 supports three ATM classes of ser-
vice for data connections: Unspecified Bit Rate (UBR), Constant Bit Rate (CBR), and Variable Bit Rate
(VBR). You can configure these classes of service on a per VC basis. The default ATM class of service
is UBR.
Quality of Service (QoS) settings
Note: QoS settings are not available on Ethernet-to-Ethernet WAN models.
• Select the QoS (Quality of Service) setting from the pop-up menu: UBR. CBR, or VBR.
UBR: No configuration is needed for UBR VCs. Leave the default value 0 (maximum line rate).
CBR: One parameter is required for CBR VCs. Enter the Peak Cell Rate that applies to the VC. This
value should be between 1 and the line rate. You set this value according to specifications defined by
your service provider.
