ALL126AS3
USER’S MANUAL
57
Notes:
1. ALL126AS3 vdsl2 vectoring technology default setting is enabled.
2. Vectoring technology is mainly used in intensive line equipment, such as 24-Port VDSL2 IP DSLAM.
3. If user would like to use ALL126AS3 vectoring technology, ALL126AS3 and IP DSLAM both need support vectoring technology
features and need both enabled. The ALL126AS3 will auto follow the IP DSLAM vectoring technology configuration.
4. Vectoring technology does not support point to point applications.
About vectoring function(Reference only):
Vectoring is a transmission method that employs the coordination of line signals for reduction of crosstalk levels and improvement of
performance. It is based on the concept of noise cancellation, much like noise-cancelling headphones. The ITU-T G.993.5 standard,
"Self-FEXT cancellation (vectoring) for use with VDSL2 transceivers" (2010), also known as G.vector, describes vectoring for VDSL2.
The scope of Recommendation ITU-T G.993.5 is specifically limited to the self-FEXT (far-end crosstalk) cancellation in the
downstream and upstream directions. The far end crosstalk (FEXT) generated by a group of near-end transceivers and interfering
with the far-end transceivers of that same group is cancelled. This cancellation takes place between VDSL2 transceivers, not
necessarily of the same profile.
