Explain how V.92 modems achieve 56 Kbps over traditional phone lines.

What will be an ideal response?

V.92 achieves 56 Kbps by skipping the modulation of analog data to digital data as it's received from the Telco. By using a technique called pulse code modulation, it then digitizes analog signals, which reduces the noise introduced in the signal and allows for more bits per second when transferring data.
