Telecom Terms
Inside Wire
The phone wire, including the associated jack, inside your home or business (and could include wire that is outside on the building) that connects your phone to the phone box where a telephone company's lines enter the building. Inside wire is owned by the customer and is their responsibility. If you rent, inside wire is your landlord or the property owner's responsibility. Inside wire does not include customer premises equipment.
Interconnection
The connection of one telecommunication carrier's network to another or the connection of a piece of telephone equipment to the nationwide telephone network.
Internet
An unregulated, global confederation of computer networks linked through regional, private business and educational networks. Millions of people in more than 50 countries use the Internet daily. The internet began in 1969 as an attempt by the Defense Department to link universities to Pentagon researchers, while also serving the national security purpose of spreading out crucial computing tasks to a wide geographic area. Today most of the Internet's growth is in the commercial sector.
IntraLATA Calling
Calls originating and terminating in the same service area (LATA).
IP - Internet Protocol
A standard protocol for transmission of data from source to destinations in packet-switched communications networks and interconnected systems of such networks. ( In comparison, think of the laws that govern the road and highways; stop, yield, one way, turn signals, stoplights.)
ISDN- BRI
Integrated Services Digital Network. A standardized design for simultaneous voice, data and video signals over a pair of twisted wires, the most common type of customer line in the telephone network.
IXC
Interexchange Carrier. Synonymous in common usage with "long-distance carrier." Under the federal Telecommunications Act, an IXC carries communications traffic across LATA boundaries. BOCs, at one time, were only permitted to carry communications within LATA boundaries. Toll or "long-distance" calls within LATA boundaries do not fall within the federal Telecommunications Act's definition of "interexchange."
