* 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 .
