Transmission component

U.S. telecommunications law
A transmission component is a communications path that enables a consumer to transmit a message to another point, with no computer processing or storing of the information, other than the processing or storage needed to convert the message into electronic form and then back into ordinary language for purposes of transmitting it over the network.

For example, when customers buy broadband access service they purchase a transmission component that facilitates the transfer of bits from their home computer to the Internet (this transmission component is often bundled with other services, like technical support and e-mail accounts).
