<p>A pulse code modulation decommutator interface (10) system is provided. The system includes a standard computer interface (16), a standard decommutator interface (18), control circuitry (20) and a memory (22). The invention thereby provides means for receiving and selectively storing a plurality of first control signals (28) from said computer and for selectively providing said first control signals to said decommutator; second means for receiving and selectively storing a plurality of second control signals from said decommutator and for selectively providing said second control signals (28) to said computer; and third means for receiving and storing data (26) from said decommutator and for selectively providing said data to said computer in accordance with a protocol established by said first and second control signals. In an extension of the invention, means are included for validating the data received from said decommutator. In a second extension of the invention, means are provided for rejecting noise in the signals received from said decommutator.</p> |
