Abstract: The present invention discusses a method and apparatus for selectively providing a power to an alarm system, such as the power source provided by a telephone company, to alarm equipment located at customer's premises in a Fiber to the Premises (FTTP) telephone network. This power source is commonly used to power the POTS lines in a Service Provider's network. Two signals, one relating to the optical connectivity of the network and one relating to the connectivity of virtual circuits, are monitored at the customer premises. A logical operation is performed so as to remove a power source if either of the two signals is lost.

Abstract: A method and five pin integrated protector and splitter module are provided for use at a protector panel of a facility for housing telephone-related equipment, where the module is capable of being used in conjunction with at least a broadband MODEM separate from a digital loop carrier. The module includes a first pair of module pins for receiving a signal including voice and data, and a protection circuit coupled with the first pair of module pins. The protection circuit includes a ground contact for coupling with a ground potential at the protector panel, for protecting telephone-related equipment from at least one of an overvoltage and overcurrent condition present at the first pair of module pins. The module further includes a splitter circuit coupled with the protection circuit, for splitting the voice from the received signal as a voice signal, and a second pair of module pins coupled with the splitter circuit, for providing the voice signal from the five pin module to the digital loop carrier.

Abstract: A guide for the formation of mortis joints using a spiral rotary cutter provides a first guide portion having faces at 90° and bisected by more than one half of its surface by a groove and a means for fastening this guide to the base of a rotary cutting tool.
