Plessey公司的新型特高速16000型调解器序列可大大提高线路利用率,并降低传输费用。这种16千比特/秒调解器是为在CCITT M1020、3002—C2或在D型线路上作点——点通信而设计的,它在标准的四线音频线路上所取得的传输质量可类比
Plessey’s new Very High Speed 16000 Modem Sequencer dramatically increases line utilization and reduces transmission costs. Designed for point-to-point communication on the CCITT M1020, 3002-C2 or D-type line, this 16 kbit / sec modem delivers analogy of the transmission quality achieved on a standard 4-wire audio line
