  • Dual mode ISDN S/U interface converter
    Patent number: 7016374
    Abstract: A dual mode ISDN S/U interface converter and a network arrangement are provided. The dual mode ISDN S/U interface converter is capable of selectively operating in either line terminator (LT) or work terminator (NT) modes by an adjustment of jumpers or other electronic switches. The ISDN S/U interface converter also provides a selectable and reversible direction of sync flow over a common path, with a common sync circuit, common control, and common data bus. With the dual mode capability of the ISDN S/U converter, a system integrator can use a single type of equipment for insertion between an ISDN switch and a multiplexer.
