<p>A two-way paging system is described which consists of a paging terminal and a plurality of remote paging units. The paging terminal is designed to receive a message from a caller and transmit the message to at least one remote paging unit. The paging terminal is also designed to receive a transmission from at least one remote paging unit and has a memory with a plurality of pre-recorded messages, parameters or destination addresses stored in the memory with each message being selectively retrievable by a unique message code. The plurality of remote paging units have a receiver for receiving a message transmitted by the paging terminal. The plurality of remote paging units also have a transmitter for transmitting a signal to the paging terminal where at least part of the signal contains a unique message code corresponding to one of the pre-recorded messages, parameters or destination addresses stored in the memory of the paging terminal. The transmission signal from the remote paging unit can be an acknowledgment message in response to a message transmitted by the paging terminal or an unsolicited message.</p> |
