Local Access and Transport Areas – Local Access and Transport Area is a U.S. term that refers to a geographic region assigned to one or more telephone companies for providing communication services. A connection between two telephone companies within the same region is referred to as intraLATA. A connection between two local exchange carriers in different regions is called interLATA, which is the same as long-distance service. Long Distance – Calling anywhere out of your local area or zip code area that you live in can be long distance calling. Although land lines only bill to the person starting the call, Cell phone carriers bill both the person calling and the person receiving the call. This is why many people don’t do long distance calling because the other person may not want to receive the charge for the call. Local Loop – In telephony, a local loop is the wired connection from a telephone company's central office in a locality to its customers' telephones at homes and businesses. This connection is usually on a pair of copper wires called twisted pair. The system was originally designed for voice transmission only using analog transmission technology on a single voice channel. Today, your computer's modem makes the conversion between analog signals and digital signals Data Over Telephone Lines – Telephone was originally invented to transfer voice. However, now you can transmit data over the telephone. The fixed-line telephone is on analog systems capable of transmitting only a narrow range of audio frequencies. Because it only transmits a small portion of the audio spectrum, it may not seem like a good choice for transmitting data. Explore Activity 3
