Interexchange Carriers (IXCs) are long-distance telecommunications service providers responsible for managing and routing communications between different local exchange areas. Unlike Local Exchange Carriers (LECs), which handle intra-local area communication, IXCs bridge the gaps across wider geographical regions, providing seamless connectivity over large distances.
Historical Context
The concept of IXCs became prominent in the 1980s following the breakup of AT&T’s monopoly in the United States. The divestiture resulted in the creation of several Regional Bell Operating Companies (RBOCs) to handle local communications while opening the market for competition in long-distance services.
Types/Categories of IXCs
- Incumbent IXCs: Originally part of the legacy monopolistic providers before the market was deregulated.
- Competitive IXCs: New entrants to the market post-deregulation, such as MCI, Sprint, and other telecom firms.
Key Events
- 1984: The AT&T breakup, leading to increased competition and the emergence of competitive IXCs.
- 1996: The Telecommunications Act of 1996 further deregulated the telecommunications market, allowing IXCs to offer local services and vice versa.
Detailed Explanations
How IXCs Work
IXCs utilize a network of fiber optic cables, satellites, and microwave radio relays to facilitate long-distance communication. They operate switches that route calls and data through various paths to their destinations efficiently and reliably.
Importance and Applicability
IXCs are critical for global connectivity. They enable businesses and individuals to communicate across cities, countries, and continents, playing a pivotal role in economic and social activities.
Mathematical Models/Formulas
While specific technical details may involve complex algorithms for routing and signal processing, a simplified overview involves:

Examples
- A call made from New York to Los Angeles is routed through an IXC.
- Internet data packets traveling between continents often traverse networks managed by IXCs.
Considerations
When choosing an IXC, factors such as reliability, pricing, network coverage, and customer service are crucial.
