What speed does V.17 commonly operate at?

V.17 is a modem standard that is designed for the transmission of data over telephone lines using analog signals. It is particularly known for its capability to operate effectively in environments with digital transmission formats. The standard specifies a modulation scheme that allows for high-speed data transfer, typically up to 14,400 bits per second (bps).

This speed is significant because it represents the maximum throughput that V.17 can achieve while maintaining a reliable connection. In practical applications, V.17 is commonly used in fax machines, providing a balance between speed and effective error correction capabilities, which is essential for delivering clear and accurate transmitted documents. The other speeds listed either reflect different modulation schemes or lower throughput capabilities that do not correspond to the V.17 specification.
