1. An apparatus comprising a transceiver operable to:
- transmit, in a full power mode, a plurality of superframes, wherein the superframe comprises a plurality of data frames followed by a synchronization frame;
transmit, in the full power mode, a synchronization signal;
receive a message to enter into a low power mode;
enter into the low power mode by reducing a power consumption of at least one portion of a transmitter;
store, in the low power mode, at least one parameter associated with the full power mode operation wherein the at least one parameter comprises at least one of a fine gain parameter and a bit allocation parameter;
transmit, in the low power mode, a synchronization signal; and
exit from the low power and restore the full power mode by using the at least one parameter and without needing to reinitialize the transceiver.

Abstract
A multicarrier transceiver is provided with a sleep mode in which it idles with reduced power consumption when it is not needed to transmit or receive data. The full transmission and reception capabilities of the transceiver are quickly restored when needed, without requiring the full (and time-consuming) initialization commonly needed to restore such transceivers to operation after inactivity.
