Abstract
A communication system (10) includes a duplex digital communication node (14) and a half-duplex digital communication node (12). The half-duplex node (12) is configured to perform duplex testing. The half-duplex node (12) digitizes a test message (74), vocodes the test message (76), possibly encrypts the test message (78), FEC encodes the test message (80), assembles the test message into frames (82), and records the framed test message (84). During a duplex test mode of operation, the node (12) retrieves the test message (92) and transmits (90) it away from the node (12). During the duplex test mode, the node (12) also receives a signal, disassembles signal data from frames (114), FEC decodes the data (116), possibly decrypts the data (118), de-vocodes the data (120), and converts the resulting data stream into analog data (122).
