4 frequency diplex system used by organizations such as Interpol and United Nations and the government Diplo services of countries such as Australia, Denmark, Holland, Norway, Pakistan and Spain. Typically runs at 100 and rarely at 200 or 300 bd. This 2 channel system supports several different shift parameters and word, bit, character or not-interleaved of the channel characters but is easy to identify because of its 4 peak signal. This system was developed by Thrane and Thrane of Denmark.
