INTRODUCTION

This document describes one of the series of Zarlink line module reference designs. Each Zarlink line module is a complete standalone line card solution applicable to specific target market
segments. When used with the Zarlink’s VoicePath software and the VoicePath demo board, this module provides a complete voice solution requiring only a power supply to operate.

This line module demonstrates all of the powerful features of the Zarlink Le58QL021 QLSLAC and the Le79R79 devices. The QLSLAC device includes A-law/µ-law and linear coding. Transmit and receive gain, two-wire AC port impedance, transhybrid balance, equalization, and hybrid balance. The Le79R79 SLIC device provides internal ring generation and ring trip detection, battery switching, programmable open circuit voltage, and a programmable loop detect threshold. Together, these devices form a complete line card solution.

SCOPE

This document describes the Le71HR0021 line module only. For information regarding the VoicePath software, the WinSLAC software, or the VP demo board please see their respective user’s guides.
