Description

The Zarlink dual channel Le88266/286 Tracking Battery Switching (ABS) VoicePort™ device implements a dualchannel
telephone line interface by providing all the necessary voice interface functions from the high voltage
subscriber line to the μP/DSP digital interface. The ABS device can operate from external battery supplies, or from
supplies generated by the on-chip switching regulator controllers. This device reduces system level cost, space and
power. Designers benefit by having a simple, cost effective, low-power and dense, interface design without
sacrificing features or functionality. The programmable, feature rich VoicePort device provides a highly functional
line interface which meets the requirements of short and medium loop (up to 1500 Ohms total at 1 REN)
applications. Features include: high voltage switching regulator, self-test, line test capabilities, integrated ringing (up
to 110 Vpk), worldwide software programmability with wideband capability, flexible signal generator with tone
cadencing and caller ID generation. These VoicePort device features are crucial for designing cost-effective, fullfeatured
Voice over Broadband solutions.
