A description using the naming convention developed in g 992 3 described above it can be written inp r u00b7 s u00b7 d 2 u00b7 n u2062 dmt u2062 u2062 symbols u2062 linerate lr 32 u00b7 n s u2062 kb u2062 u2062 s and datarate dr 32 u00b7 n r s u2062 kb u2062 u2062 s lr is the data rate including coding overhead in kbits sec dr is the net data rate available to carry data in kbits sec n is the size of the reed solomon codeword in bytes r is the number of check bytes and is even d is the interleaver depth in bytes and s is the number of dmt symbols per fec codeword lr max is the maximum data rate that can be transmitted in kbits sec s min is the minimum value of s mem d u00b7 n is a parameter designated as the interleaver memory in bytes inp min is the minimum number of dmt symbols in error that must be corrected and latency max is the maximum allowed latency delay of the modem in milliseconds first considering the case where there is no constraint on d max and s min the following two relationships are considered dr 32 s u2062 n r n s d u00b7 r 2 u00b7 inp d u00b7 n u00b7 r 2 u00b7 n u00b7 inp mem u00b7 u03b2 2 u00b7 inp dr 32 u00b7 n s u2062 1 u03b2 32 u00b7 mem u00b7 u03b2 2 u00b7 inp u2062 1 u03b2 16 u00b7 mem inp u2062 u03b2 u2061 1 u03b2 it should be noted however that the data rate dr cannot exceed the maximum line rate lr max minus the redundancy expressed as equating the two equations above.
