Global carriers are also fairly self-explanatory.
Generally, while the IXCs and many of the ILECs have international operations, global carriers are more focused on international operations, and on wholesaling international connections to other carriers. Global Crossing aims to become a central provider of telecom capacity to other carriers, large corporations, and government agencies around the world. The company sells wholesale capacity on its terrestrial and undersea networks, and is ramping up its retail services in areas such as private data lines, business long distance, and data center services, the last through its subsidiary GlobalCenter. Like many other carriers, the company is increasing its focus on international data services. The Motley Fool.
