Device Overview

Summary

The LE79271 Next Generation Subscriber Line Interface Circuit (SLIC) device, in combination with an LE792388 SLAC device, implements a DSL friendly, high density universal telephone line interface. 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. Additionally, the NGCC chip-set has integrated self-test and line-test capabilities to resolve faults to the line or line circuit.
