Single Channel VoicePort™ SLAC™ Device

ORDERING INFORMATION

*Green package meets RoHS Directive 2002/95/EC of the European

Council to minimize the environmental impact of electrical equipment.

DESCRIPTION

The Legerity Le88010 VoicePort™ SLAC™ device, in

combination with an analog DAA, implements all the voice

functions necessary to properly terminate and monitor the

customer premises side of a PSTN line and provide linear or

G.711 A- or u-Law encoded voice output over a standard PCM

or GCI highway. The Le88010 device is ideal for use in voice

enabled DSL modems that implement lifeline POTS and

support PBX functionality.

This device reduces system level cost, space, and power by

achieving a high level of voice integration and adds

programmability of transmission and signalling features.

Designers benefit by having a simple, cost effective, low power

and dense, interface design without sacrificing features or

functionality.
