Abstract
An apparatus and method are provided for obtaining, from an analog subscriber loop, test data that may be used to test the performance of a telephony communication system. The apparatus includes a digital-to-analog (D/A) converter, a first port, a second port, and an analog-to-digital (A/D) converter. The D/A converter receives digital data and converts the digital data into a first analog signal. The first port transmits the first analog signal across a first subscriber loop to a telephony communication network. The network, via A/D and D/A conversion, translates the first analog signal to a second analog signal and transmits the second analog signal to the second port via a second subscriber loop. The A/D converter receives the second analog signal from the second port and converts the second analog signal into the digital test data, which is then used to analyze the performance of the telephony communication system.
