Claim 0:
1. A method comprising:
enabling a set of T-switches, using at least one low-impedance switch driver, to connect at least four wires of a multi-wire bus to a multi-input comparator (MIC) of a plurality of MICs;
receiving, in an ensemble non-return-to-zero half-duplex mode of operation, a set of at least four input signals at the MIC and responsively generating a respective linear combination of the set of at least four input signals to detect an orthogonal sub-channel of a plurality of mutually orthogonal sub-channels, each input signal received via a respective wire of the multi-wire bus;
initiating a non-return-to-zero full-duplex mode of operation by using the low-impedance switch driver to disable a corresponding subset of T-switches to selectively disconnect a pair of wires of the multi-wire bus from the MIC;
using the selectively disconnected pair of wires to transmit a differential outbound signal;
shunting capacitively-coupled interfering outbound signals received at the MIC from the selectively disconnected pair of wires in the full-duplex mode of operation via low-impedance enable signal paths in the low-impedance switch drivers; and
generating a differential output in the full-duplex mode of operation by forming a comparison of the input signals received on at least two remaining wires of the multi-wire bus connected to the MIC in the full-duplex mode of operation.
