Classification: H04L

Abstract:
A digital subscriber line (DSL) termination unit comprising:an asynchronous transfer mode (ATM) transmission convergence circuit operative to perform transmission convergence on first ATM data to generate second ATM data; a scrambler circuit operative to create scrambled second ATM data from said second ATM data; a descrambler circuit operative to create descrambled second ATM data from said scrambled second ATM data; a compression circuit operative to create compressed second ATM data from said descrambled second ATM data; an interleaver circuit operative to create interleaved second ATM data from said compressed second ATM data prior to transmission; and a control circuit operative to control said descrambler circuit and said compression circuit, wherein said control circuit controls said descrambler circuit and said compression circuit to limit a maximum compression bandwidth.
