Claim:
A method of transmitting an admission data packet through a coaxial network, comprising: a) generating an Admission Preamble including the following symbols SS, SS, SS, SS, SS, SS, SS, SS, SS, SS, SS, SS, LS 1 , LS 1 , LS 1 , LS 1 , LS 1 , LS 1 , LS 1 , LS 1 , CP 0 , CE, CE; b) appending the Admission Preamble to a data payload; and c) transmitting the admission data payload and appended Admission Preamble over coaxial cable in a MoCA network; wherein: i) the SS symbol is defined by a 30-bit binary data input sequence, ii) the LS 1 symbol is defined by a 64-bit binary data input sequence, iii) CP 0 is a repeat of the end of the symbol, iv) CE is a 256-bit binary data sequence in which each bit is modulated on one of a plurality of active sub-carriers, v) generating comprises using the following short sequence: SS=[x001 0000 1111 1010 1101 0001 0011 101x xx00 0101 1110 0010 1101 1010 0001 00001; and wherein: vi) generating comprises using the following CE symbol: CE=[xxxx 1011 1101 0010 1111 0100 0101 0001 1001 0000 1010 1110 0110 0001 1110 0001 1101 0110 0110 0000 1101 0111 0011 0111 0011 1000 0101 0001 0010 0010 0111 0011 1111 0011 0000 1110 1011 1100 0001 0010 0010 0101 1010 1110 1001 1100 1000 1110 0000 0011 1010 1000 0111 1011 0101 1110 1110 0011 1100 0100 1011 xxxx xxxx xxxx xxxx xxxx xxxx x001 0010 1011 0100 1000 1001 0010 0000 0011 1111 1001 0100 0111 0010 1100 0010 1001 1101 1100 1100 0111 0110 0000 1100 0111 0010 0110 0110 1100 0110 1101 1110 1001 1000 0110 1110 0101 1011 0100 0000 0001 1100 1100 1100 0110 1000 1101 1100 0001 0010 0110 0001 0011 1110 0001 0001 0110 0000 1110 0010 1xxx] to generate each CE symbol; and vii) a ‘0’ represents the BPSK point {+1, 0}, a ‘1’ represents the BPSK point {−1, 0}, and an ‘x’ represents BPSK point {0, 0}.
