VDSL Configuration and Monitoring
(DES-7010 Modules Only)
For DES-7010 module installations there are four menus available to enable the VDSL Rate Adaptive
feature per port, monitor transmission power and perform a loop back test to check end-to-end
connectivity. To configure available upstream and downstream bandwidth for individual ports, see the
Port Configuration section on page 55.
VDSL Port Rate Adaptive
The VDSL Rate Adaptive function can be enabled or disabled o a per port basis. It is disabled by
default on all ports of the DES-7010 VDSL module. When the VDSL rate adaptive mode is enabled,
the switch automatically senses line condition and adjusts downstream and upstream speeds if the set
rate cannot be maintained.
To configure Port Rate Adaptive for any VDSL module, first select the Slot from the drop-down menu,
then choose which ports are to be configured in the From and To drop-down menus. Choose the Rate
Adaptive mode from the drop-down menu. Choose options Disabled, Default or Optimum.
The setting Default will set speed to Mode 0* when a rate can no longer be supported. The Optimum
setting will set speed to Mode 0 and test the downstream and upstream speeds. It then raises the
speed incrementally to achieve the best performance level.
Click Apply to let your changes take effect.
You may also use the CLI command
setting.
* Mode 0 is the default setting for VDSL ports. It specifies an upstream speed of 1 Mbps and
downstream speed of 4 Mbps. See Port Configuration on page 55 for details on how to manually
configure upstream and downstream port speeds on the DES-7010 VDSL Module.
