Low complexity, optimized power management scheme for very high speed digital subscriber line transceivers 2

An apparatus comprising:

• processor configured to:
• determine a power management (PM) state from a plurality of PM states for a digital subscriber line (DSL) transceiver, wherein the plurality of PM states comprise an idle state, a full on state, and a low power state, wherein the full on state consumes more power than the low power state, wherein the low power state consumes more power than the idle state, wherein the low power state comprises at least two PM profile, wherein the DSL transceiver supports a very high speed digital subscriber line 2 (VDSL2) data transmission protocol;
• and
• instruct the DSL transceiver to use the PM state;
• and
• transition the DSL transceiver from the PM state to a second PM state of the plurality of PM states,
• wherein the full on state comprises a full on PM profile,
• wherein each of the at least two PM profiles and the full on PM profile comprises one profile index,
• wherein transitioning the DSL transceiver from the PM state to the second PM state uses a PM command, and
• wherein the PM command comprises a profile index of the second PM state.
