Abstract: An intermediate server for conveying information, the intermediate server includes: an intermediate network interface, for receiving signals provided from a mobile phone to an access point and further conveyed over an intermediate network; wherein the signals are provided by the mobile phone over an unlicensed medium; wherein the intermediate network interface is further adapted to communicate with an intermediate network manager such as to guarantee an allocation of intermediate resources to the exchange of signals; a fixed network interface, for exchanging signals with a fixed network; and at least one translation component, adapted to apply translation mechanisms from a mobile phone protocol to a fixed network protocol.

Abstract: The present invention is directed to an ‘add-on’ device for imparting voice/sound features to a standard cable modem. A proprietary communication protocol is disclosed, which allows the add-on device and the cable modem to communicate with each other in a way that mimics the behavior of an EMTA device. The add-on device has an outline that is adapted to the outline of the cable modem, and it is mechanically secured to the cable modem by utilizing the original HFC connection of the cable modem. In order to enhance the functionality of a cable modem, the cable modem is upgraded by replacing its original software package by an upgrade software package, thereby allowing logical communication between the upgraded cable modem and the add-on device, for exchanging composite data between them.
