Policy for activating a
legacy customer
premises equipment
(CPE)
A legacy CPE is a
VDSL2 CPE
(supporting G.
993.2, not G.
993.5) that does
not support
Vectoring. If such
a CPE is activated
in G.993.2 mode
in the Vectoring
system, the
crosstalk impact
on other lines
cannot be
canceled, causing
the Vectoring
system
performance to
deteriorate. To
minimize the
impact, set the
activation policy
of a legacy CPE
based on site
requirements.
By default, the policy
for activating a legacy
CPE is set to limit.
l
no-limit
: The
Vectoring legacy
CPE is activated in
common VDSL2
mode (G.993.2
mode), or non-
Vectoring mode,
in which the
Vectoring system
performance is
affected. This
mode is used in the
Vectoring initial
phase when a large
number of CPEs
need to be
upgraded or
replaced and the
Vectoring
performance are
not concerned.
l
limit
: The
Vectoring legacy
CPE is activated in
common VDSL2
mode but the line
PSD is
automatically
shaped so that the
CPE can be
activated at a low
VDSL2 rate,
preventing
crosstalk on other
lines. This mode is
used in Vectoring
medium phase
when some CPEs
have not been
upgrade or
replaced.
