L9500A Description
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 transmission, a low-power scan state, ground start (tip open), and a forward disconnect state.
