Title: Johann Pfeiffer: Innovator in Network Technology
Introduction
Johann Pfeiffer is a notable inventor based in Vienna, Austria. He has made significant contributions to the field of network technology, holding a total of 3 patents. His work primarily focuses on methods for configuring network termination units and filter arrangements for signal separation.
Latest Patents
One of Pfeiffer's latest patents is a method for configuring a network termination unit. This invention relates to the packet-by-packet asynchronous transfer mode transmission of data. The method involves subdividing data into cells and assembling them into packets, which can be transmitted at either a constant data rate (CBR) or a non-constant data rate (UBR). The network termination unit serves as an interface between a transmission line and a data terminal, determining the number of data cells in each packet to manage the ATM connection's data rate.
Another significant patent is a filter arrangement designed for separating analog or digital baseband signals, such as POTS or ISDN signals, from digital wideband signals. This filter arrangement includes a bi-directional low-pass filter and a bi-directional high-pass filter. The low-pass filter allows direct current to flow through, while the high-pass filter is arranged in parallel to enhance signal separation.
