Latest Patents

One of Terry's latest patents involves a distribution network comprising coax and optical fiber paths. This innovation supplements a cable television network with optical fibers and fiber termination units, allowing for the communication of additional downstream digital signals and upstream signals. The drop unit for each customer premises is designed to demodulate downstream signals and selectively deliver only those addressed to the customer premises. It utilizes binary phase shift keying (BPSK) to ensure relative immunity to noise when forwarding signals. Additionally, upstream BPSK signals from the customer premises are remodulated in the drop unit, isolating the customer premises wiring from the rest of the network.

Another significant patent by Terry is a switching node for a communications switching network. This invention includes a circuit switch for establishing long-duration circuit-switched connections and an ATM message switch for communicating short-duration messages or datagrams. The control circuitry, which includes free channel queues, enables rapid communication of signaling messages throughout the network without delays. This innovative approach enhances the efficiency of circuit-switched connections.
