Description
The SLIC provides a complete interface between an
industry standard programmable CODEC or DSP
and a subscriber loop.
Functions provided include battery feed, zero
crossing ring control, programmable current feed,
power down with wake up signal, cadenced
messaging facility, switch hook & dial pulse
detection, loop length indication and the capability of
reflecting a programmable CODEC’s impedance or
supplying a standard 600 ohm impedance to the line.
The device is fabricated as a thick film hybrid using
various technologies for optimum circuit design high
reliability.
