This enables the design of a low cost, high performance, fully software programmable line interface with worldwide applicability. All AC, DC, and signaling parameters are programmable via a microprocessor interface. The Le79238 has an integrated test tool box which can be used standalone or with an NGVCP to resolve faults to the line or line circuit.
