Vectoring is classified only as system-level vectoring (SLV) and node-level vectoring (NLV) based on system...

Vectoring Classification :

Vectoring is primarily classified into two types based on the scope of crosstalk cancellation:

System-Level Vectoring (SLV) : Applies to all lines within a single DSLAM or cabinet.

Node-Level Vectoring (NLV) : Applies to lines across multiple DSLAMs or nodes.

However, these are not the only classifications. Other implementations, such as hybrid approaches, may also exist depending on the network design.

Why FALSE?

The statement incorrectly claims that vectoring is classified only as SLV and NLV, ignoring other possible implementations or variations.

Thus, the correct answer is B .
