Abstract: Importance classes are assigned to electronic messages, by identifying the sender and recipient of an electronic message, determining a relative organizational distance between the sender and the recipient, and assigning the electronic message an importance class, according to the relative organizational distance between the sender and the recipient. The importance setting is further weighted by content criteria and a plurality of rules formed by a machine learning algorithm.

Abstract: A splitterless system provides along a subscriber loop, full Ethernet wire speed data transmission between a date source and an Ethernet standard end device. The system includes a gateway modem device connected to a data source, and arranged in splitterless contact with a subscriber loop extending between a Punch Down Block (PDB), and an Ethernet standard end device; and a user modem device connected between the Ethernet standard end device and the subscriber loop so as to define with the gateway modem device a subscriber loop segment, wherein the gateway modem device and the user modem device are operative to communicate along the loop segment in different predetermined, first and second frequency spectra, for uplinking and downlinking, respectively, thus to facilitate therealong full Ethernet wire speed data transmission therealong.
