Abstract: A system that facilitates the efficient transfer of digitally encoded messages comprising an enhanced service exchange device in combination with an enhanced service message handler. The system provides alternate delivery paths for digitally encoded messages after first attempting a point-to-point connection between the sending and receiving communicating devices. The system provides re-routing functionality for both the sending and receiving of data. For sending data, the enhanced service exchange monitors point-to-point message transfer failure parameters (such as device busy signals, no answer, or telephone network re-order signals). When such conditions are encountered, it re-directs the transfer attempt to an enhanced service message handler, which may then be used as a store-and-forward switch. For receiving data, messages are redirected to the enhanced service message handler if message transfer failure parameters are detected.

Abstract: A communication apparatus generates plural data representing a modulated analog wave by sequentially reading plural data representing an analog wave from a memory storing plural data, and controlling a sequence of such plural data to be read in accordance with information to be transmitted. Such a configuration is also provided in a switchboard to transmit internal information of the switchboard.
