9.2.3 Frequency Band Plan
Each VDSL mode operates in a different frequency band allocation, resulting in different upstream
and downstream speeds. Your system automatically changes the band plan based on the loop
condition and loop length.
A band plan example is shown next. Band plans include an optional band (between 25 kHz and 276
kHz) controlled by “limit PSD mask”.
The optional band is used for upstream transmission which is to be negotiated during line initiation.
The optional band frequency (for example,
x
and
y
) varies depending on the limit PSD mask you
use.
Figure 125
A Band Plan Example
A sample of optional band PSD masks and associated frequency bands used in the Device is shown
next.
The “eu” number in the limit PSD mask is a tone index. A tone spacing, 4.3125 kHz, is used for
VDSL2 profile from 8a up to 17a. So “eu32” means the optional band ending at around 138 kHz.
See
for a list of PSD masks.
9.2.4 VDSL2 Profiles
The following table lists the supported Annex A VDSL2 profiles defined by the VDSL standard. Refer
to the ITU G.993.2 specifications for more information on other profiles. The VDSL2 profiles
available in an individual VDSL2 line card varies.
