ATM Settings.
set atm option {on | off }
Enables the WAN interface of the Motorola Netopia® Gateway to be configured using the
Asynchronous Transfer Mode (ATM) protocol.
set atm [vcc n ] 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 Motorola Netopia® Operating System
tier and the capabilities that your Service Provider offers.
set atm [vcc n ] 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 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.
•
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 these
values according to specifications defined by your service provider.
set atm [vcc n ] 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 the
specified 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 its
Sustained Cell Rate (SCR). The Peak Cell Rate (see below) must be less than, or equal to
the raw WAN (DSL) bit rate. The Maximum Burst Size (MBS) is the number of cells that can
be sent at the PCR rate, after which the PVC must fall back to the SCR rate.

You can use the CLI to set up each ATM virtual circuit.
