1. An apparatus comprising a transceiver operable to:
- transmit, in a full power mode, a plurality of superframes, wherein each superframe comprises a plurality of data frames followed by a synchronization frame;
transmit a message to enter a low power mode;
enter the low power mode by at least transmitting a flag signal;
store, in the low power mode, one or more parameters associated with the full power mode;
exit from the low power by at least transmitting a plurality of frames of known data; and
restore the full power mode by at least using the one or more parameters and without reinitializing 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.
