Claim One:
1. A process for converting feed forward and feedback filter coefficients generated by a cable modem termination system to only feed forward coefficients for use by a cable modem, comprising: accessing feed forward, hereafter FFE, and feedback, hereafter FBE, coefficients generated by a cable modem termination system upstream equalizer after processing a training burst from a cable modem, and storing said FFE coefficients in coefficient memories of a conversion filter structure having an feed forward filter, a feedback filter and a means for summing the results of each of said feed forward and feedback filters every symbol time, and storing said FBE coefficients in coefficient memories of said feedback filter of said conversion filter structure; calculating an impulse response of said conversion filter structure, as defined by a plurality of FFE only coefficients output by said conversion filter structure; and selecting a subset of FFE only coefficients from said coefficients output by said conversion filter structure which define said impulse response.
