GENERAL PURPOSE DATA CONTROL SYSTEM

摘要

A general purpose data control and information system (30-64) particularly well adapted for multiple unit (60-64) radio communications providing reliable enhancement to normal voice systems. The system provides addressing capability (Fig. 2, bits 0-15), along with data transfer (Fig. 3) and utilizes handshake and retransmisssion protocol to enhance flexibility and reliability. The system utilizes fixed length signalling packets (Figs. 2 and 3) with error correction encoding, to permit data transfer, transmitter identification and control and status monitoring.
