Title: Innovations of John B Wilkes, Jr.

Introduction

John B Wilkes, Jr. is a notable inventor based in Harvest, AL (US). He has made significant contributions to the field of telecommunications, holding a total of 6 patents. His work primarily focuses on enhancing digital subscriber line services, which are crucial for modern communication systems.

Latest Patents

One of his latest patents is a system for providing extended range ADSL service with an auxiliary POTS channel over a single-line digital subscriber link. This innovation allows for relatively low-cost asymmetric digital subscriber line (ADSL) service and auxiliary POTS service to be delivered over extended distances, specifically at least 20–25 kft. The design incorporates a hybrid ADSL-SDSL architecture that can be inserted between the central office and remote sites of an ADSL system. The transceivers at both ends utilize trellis coded pulse amplitude modulation and a data rate that aligns with the capabilities of an extended distance symmetric DSL (SDSL) loop, while also providing a 64K POTS channel.

Another significant patent is related to peak power management and active decoupling arrangements for span-powered remote terminal access platforms. This power management circuit extracts power from a wireline to power a ring generator, which produces a ringing voltage signal distributed to multiple subscriber circuits. The innovation includes a power-limited voltage converter that steps up the wireline voltage to a higher isolating voltage, ensuring that the system remains functional even when deployed at distances beyond the specified capability.
