SITOR stands for which of the following?

• A. Simplex Teletypewriter Over Radio
• B. Satellite Interface Telecommunication and Optical
• C. Simplex Integrated Telemetry and Optical
• D. Systematic Teletypewriter In Radio

Answer: (A)

SITOR is a teletype text transmission method that operates over a radio link in a simplex fashion. The expansion Simplex Teletypewriter Over Radio fits this idea exactly: it describes sending teletypewriter text one-way at a time over a radio channel. This naming reflects both the device involved (teletypewriter) and the one-directional nature of the transmission (simplex) over a radio link. Historically, this approach was used for early radio teletype networks, and the acronym itself aligns with that purpose. The other phrasing doesn’t correspond to the established expansion of this acronym.
