A modem for exchanging information between a plurality of remote DTE's and a plurality of local master DTE's is disclosed having multiple line interface and DTE interface circuits. Preferably a single microprocessor is used to process all the signals between the respective lines and DTE interface circuits. Furthermore the microprocessor is also used to calculate and update the operational parameters of the line interface circuits such as equalizer coefficients, A/D or D/A attenuator coefficients.
