At a receiver, the virtual channel table transmitted from the transmitting side is parsed, thereby determining whether the current received channel is an active or inactive channel. The network device includes: a first upstream network interface; control logic configured to: receive an e-mail message; parse the e-mail message to retrieve configuration instructions; and execute a configuration action according to the configuration instructions contained in the e-mail message. The range of voltages covered causes, from one pulse to another, the appearance or disappearance of electrochemical phenomena in the vicinity of the active electrodes. The copolyamide is crystalline and has low water absorption.
