The results provide facual data on the digital and analog performance of these circuits. Phase II of the AUTOVON Evaluation compared the performance of Special Grade Trunks, Common Grade Trunks, and Common Grade Trunks with a fixed corrective equalization. These trunks were evaluated using phase modulated and amplitude modulated type MODEM's. The MODEM's were operated at data rates of 2400, 4800, and 9600 bits per second. (Author)
