What is carrier telephony and what are the features of carrier telephone system?
Carriers are the companies that construct and maintain the networks that provide telephone services. Carrier telephony is a method of transmitting several telephone channels over a single pair of wires. It was used extensively throughout the world in the 1940s through 1980s prior to the introduction of digital transmission systems.
