Dear Forum Members,
A voice grade telephone line will pass frequencies in the approximate range of 300 Hz to 3400Hz. Modern
modems can transfer data up to 56,600 bps. How does modem achieve this high data rate given the limited
bandwidth ?
pls do help me with your answers
sincerely
R Kejriwal

The analog bandwidth of phone lines is a function of the digital telephone network and the analog-digital conversion techniques used. The digital phone network (most of the network) is based upon 64kbps channels per call.

Aloha! Richard.
