7. The home network of claim 5 , wherein the allocation burst that allocates a transmission opportunity depends at least in part on an amount of data ready for transmission in a selected transmission cycle.
8. The home network of claim 5 , further comprising a synchronization burst that synchronizes the modules to a predetermined burst transmitted by one of the modules.
9. The home network of claim 5 , wherein the data portion is variable sized.
10. The home network of claim 5 , wherein the data carried by the data portion comprises DMT (Discrete Multitone) symbol data.
11. A method for communicating in a network, the method comprising:
selecting a master module for a network from a plurality of network modules of the network;
wherein the master module is adapted to produce a burst, the burst adapted to:
signify a start of the burst with a preamble, the burst having one of a plurality of burst types that is indicated by at least a length of the preamble of the burst and a pattern of symbols in the preamble of the burst, wherein a first pattern of symbols in the preamble that corresponds to a first burst type of the plurality of burst types comprises a symbol repeated a first number of times and a second pattern of symbols in the preamble that corresponds to a second burst type of the plurality of burst types comprises the symbol repeated a second number of times;
include in a header of the burst at least one parameter for decoding the burst; and
carry data in a data portion of the burst; and
wherein the master module is further adapted to produce an allocation burst that allocates a transmission opportunity to each of the plurality of network modules to transmit bursts.
12. The method of claim 11 , wherein the symbols in the preamble periodically alternate in sign, and alternating signs of the symbols in the preamble comprise the pattern of the symbols in the preamble that, with the length of the preamble, indicate the one of the plurality of burst types of the burst.
13. The method of claim 11 , wherein the data portion is variable sized.
14. The method of claim 11 , wherein the data carried by the burst comprises QAM (quadrature amplitude modulation) symbol data.
15. A method for communicating, the method comprising:
selecting a master module from a plurality of network modules;
using the master module to generate a burst, the burst comprising:
a burst preamble, the burst preamble signifying a start of a burst and having a periodic portion, one of a plurality of burst types that corresponds to the burst being indicated by at least a pattern of symbols in the periodic portion of the burst preamble, wherein a first pattern of symbols in the preamble that corresponds to a first burst type of the plurality of burst types comprises a sequence repeated a first number of times and a second pattern of symbols in the preamble that corresponds to a second burst type of the plurality of burst types comprises the sequence repeated a second number of times;
