This paper analyses different equalization, coding and signal constellation alternatives for the proposed high‐bit‐rate (800 kb/s) digital subscriber loop transmission interface. The simulation results presented in the paper demonstrate that bit rates above 1000 kb/s at acceptably low bit‐error rates (≤ 10 −7 ) are feasible, if baseband transceivers with appropriate equalization and simple trellis coding are used. It is also shown that baseband transmission and Tomlinson precoding provide a significant performance advantage over bandpass transmission and decision‐feedback equalization, respectively.
