    摘要： A combination telephone set (such as a cordless phone) and security system control device that has a first interface means for interfacing the control device with a security system bus, a second interface means for interfacing the control device with a telephone network such as the PSTN, and a user interface means with an input means for providing user control information to the control device, the input means including means for a user to switch the control device between a telephone mode and a security system mode, an output means for providing status data to a user regarding operation of the control device, and adapted to enable a user to communicate over the telephone network when the security device is in the telephone mode. Processing means controls operation of the control device, and is adapted to switch between a telephone mode and a security system mode on receipt of a user command from the input means. When in the telephone mode, the processing means sends and receives telephony information between the user interface means and the second interface means; when in the security system mode, the processing means sends and receives security system information between the user interface means and the first interface means.

    摘要： A method of reducing noise and ingress in cable return paths is disclosed in which the return frequency spectrum is divided into two regions; one frequency region being for transmissions from in-home devices such as television settops and personal computers, and another frequency region being for transmissions from communications devices called coaxial termination units located between the drop cable and the home coaxial wiring. By locating blocking filters between the drop cable and home coaxial wiring, undesirable signals emanating in the home in the second part of the return spectrum are prevented from entering the cable return system. The location of the blocking filter reduces the noise in the second part of the return spectrum substantially and allows the establishment of reliable telecommunications services on the cable return in such second part of the return spectrum. The blocking filters can be incorporated into the coaxial termination unit and the bandwidth of such filters varied from the head-end to allow more or less bandwidth to be used by in-home devices.
