ABSTRACT:
A call management system takes records from a mainframe computer. A protocol converter converts the synchronous data output from the mainframe computer for use on asynchronous terminals. Parallel port controllers are connected to the protocol converter, and asynchronous terminals are connected to the port controllers. A local processor controls the connection of the terminals to the local procesor or to the mainframe system by sending special function codes during transmissions from the local processor. Each terminal has a special function key downloaded from the local processor which enables the terminal to switch the connection back from the host mainframe to the local processor. The protocol converter converts asynchronous signals to synchronous signals to address and update records in the main frame computer storage. The local processor controls call progress tone recognition apparatus and voice recorder or synthesizer apparatus and timing apparatus and automatic dialing apparatus for controlling a line control unit which provides DTMF signals to a local switching means and trunks leading from the exchange to dial individual numbers, recognize call progress tones and voice, begin a speech reproduction message on an answered line and switch the line to an operator's station upon completion of the message.
