ONFIGURATION
VDSL communication parameters can be set for individual ports, or
multiple parameters can be defined in a profile and applied globally to the
switch or to a group of ports. Alarm thresholds can be defined in a profile
and then applied globally to the switch or to selected ports. The switch also
provides an extensive listing of VDSL statistics.
For intelligent CPEs, the remote device can be configured for standard
Ethernet connection parameters, priority settings, and queue usage. System
status and performance counters can be monitored. And firmware can be
remotely upgraded.
Configuring Global Settings for VDSL Ports
This section describes how to configure communication parameters for all
of the VDSL ports. These global parameters include specifying the Power
Spectral Density (PSD) breakpoints and a predefined PSD mask, upstream
power backoff (UPBO) and associated mask, automatic line rate
adaptation, maximum input and output data rates, and automatic
re-training to find the optimal transmission rate.
Command Attributes
• PSD Breakpoints – Define the frequency / power level breakpoints
used in the Power Spectral Density (PSD) mask.
- Number of Breakpoints – The number of frequency breakpoints used in
the PSD mask. (Range: 0-28; Default: 28)
- Frequency Value – A frequency assigned to the corresponding
breakpoint. (Range: 0-30000 kHz)
