crosstalk matrix
Issue 01 (2014-04-30)
Function
Configure the function
of canceling the
upstream and
downstream crosstalk
in the vectoring
profile. After binding
the configured
vectoring profile to the
ports, the system
implements the
vectoring algorithm on
the ports in the
vectoring group based
on profile
configurations.
The Vectoring
algorithm is executed
every time a port in a
Vectoring group goes
online or offline. To
prevent adverse impact
on system functions
due to long-term
running Vectoring
tasks caused by
frequent online and
offline on a port, set the
policy for controlling
frequent online and
offline on ports based
on site requirements.
The vectoring
crosstalk matrix refers
to crosstalk on a port in
a vectoring group from
other ports in the same
vectoring group.

Description
By default, all ports are
bound to vectoring
profile 1.
Default value:
l Upstream crosstalk
cancelation: enable
l Downstream
crosstalk
cancelation: enable
By default, the policy
for controlling
frequent online and
offline is set to limit.
Before querying
information about the
vectoring crosstalk
matrix, ensure that the
global vectoring
function is enabled and
the specified port is in
a vectoring group and
activated.
