Title: Daniel DeLiberato: Inventor in Modem Connectivity and Voice Quality

Introduction

Daniel DeLiberato is an inventor based in Natick, Massachusetts, whose patent work addresses telecommunications systems. His inventions focus on improving modem connectivity and managing voice quality in communications networks. He is associated with Cisco Technology, Inc. and holds 3 patents.

Latest Patents

One of DeLiberato’s patents, “Using Modem Profiles to Improve Connectivity, Connect Timing, and Compression Performance on a Modem Relay (MR) Gateway,” describes using stored modem profiles to help negotiate compression parameters over a modem relay connection. A gateway identifies the calling or called modem and uses its profile to send candidate commands or responses. The invention also describes storing parameters achieved during calls and establishing profiles through preliminary calls.

Another patent, “Dynamic Attenuation Method and Apparatus for Optimizing Voice Quality Using Echo Cancellers,” concerns adjusting attenuation in an echo path during a telephone call. The system measures echo return loss and gradually reduces attenuation when conditions allow, stopping when the minimum level needed for reliable double-talk detection is reached.

Career Highlights

DeLiberato’s patent work reflects a focus on practical improvements to telecommunications performance. His inventions address both modem-relay negotiation and echo-cancellation systems, with the aim of improving connection behavior and voice quality.

Collaborations

DeLiberato is associated with Cisco Technology, Inc. His listed coworkers include Nathan Richmond Melhorn and Alex Urquizo.
