ABSTRACT:
A communication system (200) for providing analog signals comprises a terminal (220) for generating tone and voice signals on tone and voice lines (230, 235), respectively, and a signal processor (205) coupled to the terminal (220) for processing the tone and voice signals. The tone signals are coupled to an analog output (215) when the tone signals are determined to be present on the tone lines (230), and the voice signals are coupled to the analog output (215) when the tone signals are determined to not be present on the tone lines (230).
