DESCRIPTION
The Zarlink 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 encode d vo ic e ou tpu t over a s tandard 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 ben efit by having a simple, co st eff ective, low p ower
and dense, interface design without sacrificing features or
functionality.
