DSL Commands
ATM Settings. You can use the CLI to set up each ATM vir tual circuit.
set atm option {on | off }
Enables the WAN inter face of the Motorola Netopia® Gateway to be configured using the
Asynchronous Transfer Mode (ATM) protocol.
set atm [vcc n ] option {on | off }
Selects the vir tual circuit for which fur ther parameters are set. Up to eight VCCs are sup-
por ted; the maximum number is dependent on your Motorola Netopia® Operating System
tier and the capabilities that your Ser vice Provider offers.
set atm [vcc n ] qos service-class { cbr | ubr | vbr }
Sets the Quality of Ser vice class for the specified vir tual 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 ser vice 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 ser vice 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 vir tual 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.
