Claim:
1. A remote node for bi-directional digital audio data and control communications, the remote node comprising: remote components that comprise a remote transceiver, and a remote low-voltage power supply that provides power to the other remote node components; wherein the remote node is configured to connect to a host end and to one or more other remote nodes via a two-wire communication network comprising twisted wire pairs; wherein each twisted wire pair forms a respective data transmission line (1) for carrying bi-directional digital audio data and digital control signals, and (2) upon which low voltage power is superimposed; wherein the remote node is enabled to receive over the two-wire communication network digital audio data and digital control signals, and is enabled to transmit over the two-wire communication network digital control signals; and wherein the remote power supply has an input that is configured to be coupled to the two-wire communication network to derive the power for the remote node from power coupled to the network by the host end.
