DSL modem apparatus and initialization method for DSL communication

摘要

An ADSL modem apparatus including an IFFT unit that performs an inverse fast Fourier transform on transmission data, an FFT unit that performs a fast Fourier transform on reception data, and a processor that performs an initialization sequence according to a protocol, is provided. During the initialization sequence, the processor maintains and enables an interleave memory to be employed. After data transmission is initiated, the processor instructs a switch controller so that an interleave unit and de-interleave unit can use the interleave memory.
