Presently, Unspecified Bit Rate (UBR) and Constant Bit Rate (CBR) are
available. You can specify the Peak Cell Rate (PCR) in kbps. This panel also
allows you to specify the period for the Operations And Maintenance (OAM) F5
(virtual channel) timer. If the period is set to zero, the OAM F5 loopback cell is
not sent. If the period is set to a non-zero value, the loopback cell is transmitted
to the remote peer according to the specified period. Note that the local peer will
always respond to a loopback cell that is transmitted by the remote peer.
Once you have finished setting these parameters, click Apply to review the
parameters you have entered and then click Finish to send settings to the
NetDSL. Click Exit to return to the NetDSL Manager.
