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.
Figure 6- 30. VDSL Port Rate Adaptive Configuration
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
config vdsl_port rate adaptive mode
to change this
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.
