Bertrand Gerbault

Title: Bertrand Gerbault: Innovator in SDH Frame Technology

Introduction

Bertrand Gerbault is a notable inventor based in Paris, France. He has made significant contributions to the field of telecommunications, particularly in the area of Synchronous Digital Hierarchy (SDH) frame technology. His innovative approach has led to the development of a unique method for interleaving and deinterleaving SDH frames.

Latest Patents

Gerbault holds a patent for a "Method and system for interleaving and deinterleaving SDH frames." This patent describes a method where STM-1 and STM-N SDH frame pointers are transmitted between a transmitter and a receiver. Each frame consists of a section overhead area, a pointer area, and a payload area that includes the data to be transmitted. At the transmitter, the bits of the pointer area and those of the payload area are interleaved according to a specific interleaving law. This process retains the position modulo 24 in the interleaved bits. The resulting interleaved frame is then transmitted to the receiver, where it is deinterleaved using a law that is the reciprocal of the interleaving law. This innovative method interleaves all the bits of pointers in the frame without altering the values of the B1 and B2 parity control bytes.
