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.

This is an email that is automatically sent out from your account whenever an email is received, to the sender of the email. This is also known as an autoresponder. Some systems allow you to set up more than one vacation reply (autoresponder) and it will select which one to send out based on features of the incoming message, which you specify. For example, any messages from your colleagues may receive one message, whereas messages from external clients receive another.
