ABSTRACT:
A method and apparatus for testing a customer premises equipment (CPE) alert signal detector used to detect the start of a Caller ID data transmission using test CPE alert signals generated by a testing platform and mixed with a voice signal as an input to the detector. The testing platform also generates a special sync signal which is input to control circuitry connected to the CPE alert signal detector. An active sync signal indicates when a valid CPE alert signal should be detected. The control circuitry is configured to execute a test algorithm that monitors both the sync signal and the output of the detector and indicates when the CPE alert signal detector has validly detected a CPE alert signal, falsely detected a CPE alert signal, or failed to detect a CPE alert signal. The number of valid, false, and missed CPE alert signal detections are totaled and can be used to calculate the talkoff and talkdown error rates for the detector.
