Abstract: A graphical solutions development system using placement of blocks representing hardware/software functionality on a computer screen drawing and connecting the blocks by wires representing data and control flow to create application programs and/or hardware design. The blocks are instances of development components that include intelligence for optimization within a detected environment. This permits effective programming of digital signal processors and system design by users not expert in digital signal processing programming and system design.

Abstract: A method and apparatus is described for providing extended subscriber features, e.g., equal access, to otherwise non-conforming central offices of a telephone switching system. According to the invention, a register module is interposed between the subscriber line and an input of the central office for intercepting digits from the subscriber line intended for the central office and for receiving subscriber information from the central office identifying the subscriber line. The register module includes a memory having a plurality of address locations and a control circuit for analyzing the intercepted digits to determine whether processing of the subscriber call requires an extended subscriber feature. If so, the intercepted digits are processed to generate a coded signal, the coded signal including the address location where the stored digits and the subscriber information resides in the memory.
