EIA/ITU PABX SLIC with 30mA Loop Feed
The Intersil SLIC incorporates many of the BORSHT
functions on a single IC chip. This includes DC battery feed,
a ring relay driver, supervisory and hybrid functions. This
device is designed to maintain transmission performance in
the presence of externally induced longitudinal currents.
Using the unique Intersil dielectric isolation process, the
SLIC can operate directly with a wide range of station battery
voltages.
The SLIC also provides selective denial of power. If the PBX
system becomes overloaded during an emergency, the SLIC
will provide system protection by denying power to selected
subscriber loops.
The Intersil SLIC is ideally suited for the design of new digital
PBX systems, by eliminating bulky hybrid transformers.
