Telefonos De Mex Sa A (TFONF)

Telefonos de Mexico, S.A.B. de C. owns and operates a fixed-line telecommunications system in Mexico, where it provides fixed-line telephony services. Telefonos also provides other telecommunications and telecommunications-related services such as corporate networks, Internet access services, information network management, telephone and computer equipment sales and interconnection services to other carriers. The company's charges for fixed-line local telephone service include: installation charges; monthly line rental charges; monthly measured service charges; digital services and charges for other services, such as the transfer of a line to another address and reconnection. Telefonos offers a number of domestic long distance discount plans that reduce the effective rates paid by its customers based on volume, time of use or other factors. Corporate networks consist of the transmission of voice, video and data between two or more end points using private circuits. Telefonos's broadband service, Infinitum, allows its customers to use its high-capacity connectivity services with applications such as video-conferencing, file transfer, terminals and e-mail. Infinitum operates over Asymmetric Digital Subscriber Line, or ADSL, technology. The company provides various other telecommunications and telecommunications-related products and services, including sales of computer and telecommunications equipment and accessories, public phones, Internet portals and billing and collection services to third parties. The company's wireless network is mainly used to provide voice, data and Internet access services, based on terrestrial or satellite platforms, to customers who are geographically far from its fiber optic infrastructure. Telefonos's transport network is fully redundant and is supported by optic rings and equipment using Synchronous Digital Hierarchy, or SDH and Next Generation SDH technologies, which allow the network to be restored within 50 milliseconds and minimize the risk of signal interruption in the event of a system failure. The company's digital microwave network serves as backup to the fiber optic network and as a main means of transmission in rural areas and small towns where fiber optic infrastructure is not available. Voice processing in its network is controlled by digital local and long distance telephone exchanges employing high levels of redundancy and load sharing to enhance network availability and service quality. All of the Company's IP-based services are offered through a multiservice IP/MPLS platform. IP/MPLS is a high-capacity, high-performance network platform based on service convergence and is designed to complement its transport network, a feature that allows it to expand its backbone network with routes of up to 10 Gbps, maintain redundant routes and offer national coverage of its IP-based services.
