DESCRIPTION

The Zarlink dual channel Le88211/231 Tracking Battery

VoicePort™ device implements a dual-channel telephone line

interface by providing all the necessary voice interface

functions from the high voltage subscriber line to the µP/DSP

digital interface. This device reduces system level cost, space,

and power by achieving the highest level of voice integration

possible. Designers benefit by having a simple, cost effective,

low power and dense, interface design without sacrificing

features or functionality. The programmable, feature rich

VoicePort devices provide a highly functional line interface

which meets the requirements of short and medium loop (up to

1500 Ohms total) applications. Features include: high voltage

switching regulator, self-test, line test capabilities, integrated

ringing (up to 140-Vpk), worldwide software programmability,

flexible signal generator with tone cadencing, caller ID

generation and all BORSCHT functions. These VoicePort

device features are crucial for designing cost-effective, full-

featured Voice over Broadband solutions.
