TT2300, also known as TT2300B, TT2300-ARQAutomatic Repeat reQuestAutomatic Repeat Query, TRA-2300, and TPLEX, is an 8MFSK synchronous system developed by Thrane & Thrane of Denmark (acquired by UK defense firm Cobham in 2012). TT2300 was used by French diplomatic services, UK Civil Aviation Authority (National Air Traffic System/NATS datalink, Prestwick/Reykjavik), and Algerian oil companies. Thrane & Thrane's name for this protocol/coding is TPLEX, not to be confused with TWINPLEX.


Characteristics[edit]

TT2300 runs at 100 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second. (300 bpsBits per second (bps)) or 200 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second. (600 bpsBits per second (bps)) and uses 8-bit ASCII encoding. Each of the 8 tones uses 200 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). spacing for ~1600-1700 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). bandwidth.

TT2300 looks and sounds very similar to 2G ALE at 100 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second.. To distinguish, TT2300 has an ACFAutoCorrelation Function of ~320 msmilliseconds (.001 of a second) for both 100 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second. and 200 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second..



Samples[edit]

100 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second. 200 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second.
