Title: Innovations by Anthony J O'Toole
Introduction
Anthony J O'Toole is a notable inventor based in San Jose, CA, with a significant contribution to the field of telecommunications. He holds a total of 6 patents that showcase his expertise and innovative spirit. His work primarily focuses on improving digital-subscriber line technologies and enhancing the quality of voice and data transmission.
Latest Patents
One of his latest patents is related to time-multiplexed transmission on digital-subscriber lines synchronized. This invention addresses the high cross-talk interference found in pulp-insulated telephone cables, which are common in Japan and other countries. The deployment of newer xDSL systems in Japan has faced limitations due to this interference, particularly the near-end cross-talk (NEXT) from ISDN services using time-compression multiplexing (TCM). O'Toole's TCM-DSL technology eliminates NEXT interference by synchronizing transmission and reception with the TCM ISDN equipment, allowing for higher-speed data transmission with reduced interference.
Another significant patent involves an integrated line card for asymmetric digital-subscriber lines (ADSL). This innovation terminates ADSL copper-pair connections at a single point in a central office, utilizing a digital splitter instead of bulky analog frequency-splitters. The digital-signal processor (DSP) performs all necessary decoding, encoding, compression, and formatting for both ADSL and plain-old-telephone-service (POTS) signals, improving the overall quality of the phone line.
Career Highlights
Throughout his career, O'Toole has worked with prominent companies such as Cirrus Logic Inc. and Centillium Technology. His experience in these organizations has contributed to his development as an inventor and has allowed him to collaborate with other talented professionals in the field.
Collaborations
Some of his notable coworkers include Shahin Hedayat and Sriraman Chari, who have also made significant contributions to telecommunications technology.
