Abstract

A hand-held cable communicator unit for technicians that enables voice and data communications across a cable network. The communicator includes a cable connector, a diplex filter, a transceiver circuit, an audio circuit and a control circuit. The transceiver circuit tunes to selected downstream and upstream channels signals. The audio circuit enables bidirectional voice communications using the selected channels signals via the cable network. The control circuit establishes a communication link and initiates and terminates communications. A communication system for field technicians of a cable network includes at least one communicator and a central communicator located at a point of distribution of the cable network. The central communicator includes transceivers, a switch matrix and a controller. Each central transceiver establishes a communication link with any linked communicator. The switch matrix forwards upstream and downstream communications between linked communicators. The controller performs functions to establish communication connections.
