Recommendation ITU-T G.9701 specifies a gigabit broadband access technology that exploits the existing infrastructure of wire-pairs that were originally deployed for POTS services. Equipment implementing this Recommendation can be deployed from fibre-fed distribution points (FTTdp) located very near the customer premises, or within buildings (FTTB). This Recommendation supports asymmetric and symmetric transmission at an aggregate net data rate up to 1 Gbit/s on twisted wire-pairs using spectrum up to 106 MHz and specifies all necessary functionality to support far-end crosstalk (FEXT) cancellation between multiple wire-pairs and facilitates low power operation.
