Programmable universal signaling circuit for a telephone network

摘要

A programmable universal signaling circuit for use in a universal channeling unit of a telephone network. The programmable universal signaling circuit uses a line converter and decoder circuit which under control of a microprocessor generates a unique set of configuration signals for configuring the universal signaling circuit into one of a plurality of standard signaling telephone circuits. The universal signaling circuit can be reconfigured either at the location of the universal channel unit or remotely.
