| 1. A method of transmitting data over a communication network where a frame is transmitted at a baud rate R, the method comprising
the steps of:
determining the maximum bit per symbol rate of modulation for the Ld bits of data where Bi is the bit per symbol rate of the
modulation;
encoding the Ld bits resulting in L encoded bits, where the ratio of the number of symbols in the frame (R*T) to the number
of symbols in a slot (Ld+x/Bi) is an integer, wherein x is a number of error correction bits;
modulating the L encoded bits using the modulation having the Bi bit per symbol rate;
mapping the L encoded bits into an integer number of time slots of the frame; and
transmitting the L bits in the slots of the frame over the communication network.
