242CONFIG CommandsThis section describes the keywords and arguments for the various CONFIG commands.DSL CommandsATM Settings. You can use the CLI to set up each ATM virtual circuit.set atm option {on | off }Enables the WAN interface of the Netopia Gateway to be configured using the Asynchro-nous Transfer Mode (ATM) protocol.set atm [vccn] option {on | off }Selects the virtual circuit for which further parameters are set. Up to eight VCCs are sup-ported; the maximum number is dependent on your Netopia Operating System tier and thecapabilities that your Service Provider offers.set atm [vccn] qos service-class { cbr | ubr | vbr }Sets the Quality of Service class for the specified virtual circuit – Constant (cbr), Unspeci-fied (ubr), or Variable (vbr) Bit Rate.• ubr: No configuration is needed for UBR VCs. Leave the default value 0 (maximum linerate).• cbr: One parameter is required for CBR VCs. Enter the Peak Cell Rate that applies tothe VC. This value should be between 1 and the line rate. You set this value accordingto specifications defined by your service provider.• vbr: Three parameters are required for VBR VCs. Enter the Peak Cell Rate, the Sus-tained Cell Rate, and the Maximum Burst Size that apply to the VC. You set thesevalues according to specifications defined by your service provider.set atm [vccn] qos peak-cell-rate { 1 ...n }If QoS class is set to cbr or vbr then specify the peak-cell-rate that should apply to thespecified virtual circuit. This value should be between 1 and the line rate.The Peak Cell Rate (PCR) should be set to the maximum rate a PVC can oversubscribe itsSustained Cell Rate (SCR). The Peak Cell Rate (see below) must be less than, or equal to
