Device Overview

Summary

The LE792388 Next Generation Octal Subscriber Line Audio-processing Circuit (SLAC), in combination with the single channel LE79271 or dual LE79272 SLIC, implements a DSL friendly, high density 8-channel universal telephone line interface with wideband capability. 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 LE792388 has an integrated test tool box which can be used standalone or for high density line cards you can offload a lot of the basic call control and test functions to the LE79124 or LE79128 VCP to help manage calls or resolve faults to the line or line circuit. A full API is available to run on a host processor to simplify software integration.

Low Density Chip Set:
Octal SLAC (codec) + Long Loop SLICs
Le792388 (codec) + Le79271 (SLIC) / Le79272 (Dual SLIC)
ZL792588 (codec with External/ Internal Ringing) + Le79271 (SLIC) / Le79272 (Dual SLIC)
