Title: Prakash Appanna: Innovator in Asymmetrical Digital Subscriber Line Technology
Introduction
Prakash Appanna is a notable inventor based in Santa Rosa, CA (US). He has made significant contributions to the field of telecommunications, particularly in the development of protocols for asymmetrical digital subscriber lines (ADSL). With a total of 3 patents to his name, Appanna's work has enhanced the efficiency and reliability of data transmission over existing telephone infrastructures.
Latest Patents
One of his latest patents is the "Asymmetrical Digital Subscriber Line (ADSL) Downstream High Speed Cell Bus Interface Protocol." This innovation allows ADSL cell packets to be transmitted downstream from an ADSL bank control unit (ABCU) to multiple ADSL line units at a high rate of throughput. It features flexible and efficient bandwidth allocation while reducing error probability. The frame boundaries of this ADSL frame are derived from a conventional subscriber bus interface (SBI) frame, enabling compatibility with existing channel banks.
Another significant patent is the "Asymmetrical Digital Subscriber Line (ADSL) Upstream Subscriber Bus Interface (SBI) Protocol." This protocol provides a SBI frame format that ensures compatibility between an ADSL line card and either an ABCU or a conventional narrowband bank control unit (BCU). It also allows compatibility between a conventional plain old telephone service (POTS) line card and both the ABCU and the conventional narrowband BCU.
