DESCRIPTION

The Le79228 Quad Intelligent Subscriber Line Audioprocessing Circuit (ISLAC™) device, in combination with a

VE790 series ISLIC™ device, implements a four-channel

universal telephone line interface. This enables the design of a

single, low cost, high performance, fully software

programmable line interface for multiple country applications.

All AC, DC, and signaling parameters are fully programmable

via microprocessor or GCI interfaces. Additionally, the

Le79228 Quad ISLAC device has integrated self-test and linetest capabilities to resolve faults to the line or line circuit. The

integrated test capability is crucial for remote applications

where dedicated test hardware is not cost effective.
