DESCRIPTION
This field displays downstream (DS) and upstream (US) rate adaptive settings.
Manual displays if the system fixes the transmission rate as the minimum net
data rate and disables transmission rate adjustment. If the attainable speeds
cannot match configured speeds, then the link may go down or communications
may be sporadic due to line errors and consequent retransmissions.
AdaptInit displays if the system keeps the transmission rate negotiated
between the system and CPE devices. It ranges from the configured minimum
to the maximum net data rate based on the initial line condition.
Dynamic displays if the system dynamically changes the transmission rate
negotiated between the system and CPE devices during initialization as well as
during SHOWTIME status.
Click the Modify link to take you to a screen where you can configure detailed
rate adaptive settings.
The MIB PSD mask allows you to further adjust PSD level for tones according to
the limit PSD mask you have configured.
This field displays how many break points are configured for the downstream
(DS) and upstream (US) MIB PSD mask. For example,"DS:4 BP US:5 BP"
displays after you have configure 4 break points for downstream and 5 break
points for upstream in the MIB PSD mask.
Click the Modify link to take you to a screen where you can configure the MIB
PSD mask.
This field displays whether DPBO is enabled or disabled in this profile.
Click the Modify link to take you to a screen where you can configure detailed
DPBO settings.
This field displays the RFI band setting in this profile.
Click the Modify link to take you to a screen where you can configure detailed
RFI band settings.
This field displays whether virtual noise is enabled or disabled in the
downstream and upstream transmissions.
Click the Modify link to take you to a screen where you can configure detailed
virtual noise settings.
Click Apply to save the changes in this screen to the system's volatile memory.
The system loses these changes if it is turned off or loses power, so use the
Config Save on the navigation panel and then the Save button to save your
changes to the non-volatile memory when you are done configuring.
The new or modified VDSL2 line profile then displays in the summary table
below.
While you are modifying a profile, you can click New to start configuring a fresh
profile without saving your changes.
Click Cancel to start configuring the screen again.
