Description
The Microsemi Le89156 is an integrated, cost effective
single channel FXS device that is optimized for VoIP
access devices. It implements a complete BORSCHT
functionality by providing the necessary voice interface
functions to power, ring, signal, and connect one or
more telephones. On the digital side, the Le89156
provides standard MPI and PCM interfaces to leading
VoIP processors.
