2007 Annual Report

TDS Telecom

TDS Telecom continues to make excellent progress as it transitions its business model from a traditional wireline telephone company to a broadband-focused enterprise. ILEC equivalent access lines increased slightly to 762,700, due to the rapid rise in the number of ILEC access lines equipped for DSL. Overall, equivalent access lines declined 1.3 percent to 1,197,700. Cost reduction initiatives at TDS Telecom enabled the company to increase its operating income 10 percent, to $141.2 million, despite a 1.8 percent decrease in its total operating revenues.

Digital Subscriber Line (DSL) Business
The company made substantial additional gains in its DSL business, increasing the combined (ILEC and CLEC) number of DSL customers to 186,800 and growing combined DSL revenues by 32 percent compared to 2006. TDS Telecom also increased the DSL speeds and services offered to its residential and commercial customers. Certain residential customers can now choose speeds up to 15Mbps, while some of the company’s commercial customers have data speed options that can provide up to 1000Mbps.

Triple Play Bundling
The company aggressively marketed its Triple Play bundles of voice, high-speed data, and DISH Network™ television services to gain new revenue-generating units, to retain existing customers by reducing churn, and to make its service offerings more attractive to customers who might otherwise choose services from cable competitors. The bundles include a combination of broadband (speeds of up to 15Mbps), unlimited local and long distance calling, DISH Network television, and services such as call waiting, caller ID, three-way calling, and more.

Commercial Broadband Services
TDS’ CLEC business, TDS Metrocom, which focuses primarily on commercial customers, rolled out Dynamic XData services to its small business customers. Dynamic XData uses Voice over Internet Protocol (VoIP) technology to deploy voice and data services efficiently over a T-1 line. Depending on location, ILEC and CLEC business customers can also choose from dedicated, managed Ethernet service (3Mbps), dedicated DS3 Internet Access (10-40Mbps), and GigaNet service (up to 1000Mbps).

In January 2008, TDS Metrocom introduced fixed wireless WiMAX digital phone and high-speed Internet service to nearly 65,000 potential customers in the Madison, Wisconsin area. Response to date has been enthusiastic, and the company is working to expand availability in other markets.

Regulatory Issues
TDS Telecom continued its work with state and federal regulatory agencies to seek to assure that the right regulatory decisions are made on key issues, such as access rates, affecting the company’s customers and its prospects for future growth.
