Application ID: 06335516

Base Claim:
1. A system of the type responsive to signals from a telephone set, said signals including a plurality of distinct interconnection supervisory signals, said system including translation means for converting said supervisory signals into a computer compatible code, and means for transmitting respective computer compatible codes to a computer device, said translation means comprising: decoder means, responsive to said signals from said telephone set, for generating a first digital code word indicative of the particular supervisory signal present in said signal from said telephone set; a plurality of translator means, each translator means responsive to said telephone signals and for generating a respective second code word indicative of different predetermined sequences of said supervisory signals; memory means, responsive to address signals applied thereto and including at least one individually addressable location corresponding to each symbol in said computer compatible code containing indicia of the corresponding code symbol, for generating an output signal indicative of the contents of an addressed location therein in accordance with said address signals; means for applying said first code word to said memory means as a portion of said address signal; selector means, responsive to control signals applied thereto, for selecting one of said plurality of translator means, and applying the second code word generated by said selected translator means to said memory means as another portion of said address signal; and means, responsive to said memory means output signals and a strobe control signal applied thereto, for selectively transmitting indicia of said symbol code to said computer.

Claim 10:
10. The system of claim 1, wherein one of said plurality of translator means comprises: first detector means, for generating latch command signals indicative of the occurrence of relatively long duration supervisory signals having durations longer than a predetermined period; latch means, responsive to said latch command signals, for responsively storing indicia of at least a portion of said first code word corresponding to said long duration supervisory signals for application to said memory means as said second code word; and means, response to relatively short duration supervisory signals, for responsively generating a strobe control signal to said means for selectively transmitting, to effect transmission of the symbol code indicia from the instantaneously addressed location in said memory means.
