ITU-T G.9963 PDF

This Recommendation describes the modifications to [ITU-T G.9960] and [ITU-T G.9961] that are needed to define MIMO home networking transceivers for operation over power-line or telephone wiring. More specifically, this Recommendation includes the following:

• the PHY functional models of the MIMO transceivers;

• detailed descriptions of the modifications (changes and additions) needed in the PHY and DLL sections relative to [ITU-T G.9960] and [ITU-T G.9961];

• the means by which transceivers that comply with [ITU-T G.9960], [ITU-T G.9961] and this Recommendation [ITU-T G.9963] interoperate when operating on the same wires; and

• the means by which transmissions from [ITU-T G.9963] transceivers do not degrade the performance of transceivers that comply with [ITU-T G.9960] and [ITU-T G.9961] when operating on the same wires.

An [ITU-T G.9963] transceiver shall be fully compliant with [ITU-T G.9960] and [ITU-T G.9961].

NOTE – In those regions, or particular installations, where only two conductors are used for mains sockets in the case of powerline or a single pair of wires is used in the case of telephone cable, a modem equipped with a MIMO transceiver will behave as an [ITU-T G.9960] transceiver.
