Title: James A. Johnanson and His Patent for Testing CPE Alert Detectors.
Introduction
James A. Johnanson is an inventor associated with Emmaus, Pennsylvania. His patent work addresses the testing of customer premises equipment (CPE) alert signal detectors, which help identify the start of Caller ID data transmissions.
Latest Patents
Johnanson is credited with 1 patent: “Method and Apparatus for Testing Customer Premises Equipment Alert.” The invention tests a CPE alert signal detector by mixing test alert signals with a voice signal and supplying the combined input to the detector. A testing platform also generates a synchronization signal for control circuitry. The circuitry monitors that signal alongside the detector’s output to identify valid detections, false detections, and missed detections. Totals for these outcomes can be used to calculate the detector’s talkoff and talkdown error rates.
Career Highlights
Johnanson’s listed company is Lucent Technologies Inc. His patent reflects work on evaluating the reliability of telecommunications equipment used in Caller ID signaling.
