Abstract

Abstract A system is disclosed for serving coin telephone calls on a wholly automatic basis without any operator intervention normally being required either for notifying the calling party of the required deposits or for monitoring the collection of coins deposited in the coin station. Moreover, coin tone detectors and announcement circuits are isolated so that coin deposits can be detected during announcements.
