Court prepares to hear challenges to FCC's Universal Service order

Groups filing challenges include AT&T, C Spire Wireless (formerly Cell South), Halo Wireless, the National Association of State Utility Consumer Advocates, the National Telecommunications Cooperative Association and the Choctaw Telephone Company.

Public utility boards in Pennsylvania, Vermont and Ohio have also joined the suit. 

The FCC's Universal Service Fund was originally designed to subsidize landline phone access in rural areas. Under the new plan, the $4.5 billion high-cost portion of the fund will be renamed the "Connect America Fund" and will be used to expand broadband Internet access.

The program is funded through monthly charges on consumer phone bills.

The agency's order also made changes to the intercarrier compensation rates phone companies pay one another to connect calls.

The FCC voted for the changes in October and released the full 740-page order in November.
