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.
