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. Carrier telephony systems ranged from single channel systems that transmitted one carrier channel on top of a normal voice frequency channel to co-axial cable systems that had thousands of channels. It was mostly used to provide trunk lines between cities although subscriber carrier systems did exist.
