Latest Patents

John S. Tsai holds a patent for a "Call service initialization arrangement." This invention allows call services defined in service profiles stored in a switching system to be enabled for individual terminals without the need for assigning terminal endpoint identifiers or virtual channel identifiers at subscription time. The system enables call services for a terminal when it transmits two identifiers to the switching system, one identifying the terminal and the other defining a service profile. The switching system includes the identifier of the service profile in broadcast messages to address terminals with features defined by that service profile. Two embodiments of the invention are applicable, one in a narrowband integrated service digital network (ISDN) and the other in a broadband ISDN (BISDN).
