Abstract
A device and method for generating a test signal for testing communication system demultiplexing equipment in which voice grade channels are designated to receive a real time input when a test signal is provided to the demultiplexing equipment. A bit stream representing a multiplex of test pattern data is generated and modified by inserting identifiers into the bit stream to indicate portions of the bit stream where real time information is to be inserted. The indicated portions of the modified bit stream are overwritten with the real time input.
