L9500A - High-Voltage Ringing SLIC
This device is optimized to provide battery feed, ringing, and supervision on short-loop plain old telephone service (POTS) loops.
This device provides power ring to the subscriber loop through amplification of a low-voltage input.
It provides forward and reverse battery feed states, onhook transmis
