Telecommunications - An acoustoelectric transducer and a keying relay connected so that the keying relay is actuated when sound, or voice, energy above a certain threshold is sensed by the transducer. Note: A vox is used to eliminate the need for push-to-talk operation of a transmitter by using voice energy to turn on the transmitter. Synonyms voice operated relay circuit, voice operated transmit.

Telecommunications - Sets of telecommunications protocols and interfaces defined by CCITT (now ITU-T) Recommendations. Note: Some of the more common V.-series Recommendations are:
- V.21: A CCITT Recommendation for modem communications over standard commercially available lines at 300 b/s. This protocol is generally not used in the United States.
- V.22bis: A CCITT Recommendation for modem communications over standard commercially available voice-grade channels at 2,400 b/s and below.
- V.32: A CCITT Recommendation for modem communications over standard commercially available voice-grade channels at 9.6 kb/s and below.
- V.32bis: A CCITT Recommendation for modem communication over standard commercially available voice-grade channels at 14.4 kb/s and below.
- V.34: An ITU-T Recommendation for modem communication over standard commercially available voice-grade channels at 28.8 kb/s and below.
- V.42: A CCITT Recommendation for error correction on modem communications.
- V.42bis: A CCITT Recommendation for data compression on a modem circuit.
- V.FAST: A new CCITT Recommendation for high-speed modems currently under development.
