Description
The SLIC provides a complete interface between a
switching system and a subscriber loop. Functions
provided include battery feed and ringing feed to the
subscriber line, 2-Wire to 4-Wire hybrid interfacing,
constant current feed with constant voltage foldback,
and dial pulse detection. The device is fabricated
using thick film hybrid technology in a 20-pin single
in-line package.
