CenturyLink, Inc. on June 17 filed a motion to strike what it called the “irretrievably flawed” data framework underlying the Federal Communications Commission’s recent business data services proposal.

AT&T, Cincinnati Bell, Consolidated Communications, FairPoint Communications, and Frontier Communications joined CenturyLink in filing the motion. 

The motion comes in response to recent acknowledgements by four of the largest cable providers that they significantly undercounted the number of locations that are capable of providing business data services and thus deemed competitive.

The cable companies’ most recent FCC filings reflect 22 times more Ethernet-capable locations than the data on which the FCC based its May 2 further notice of proposed rulemaking (FNPRM).

“We are extremely concerned that the FCC’s latest business broadband proposal is now based on fatally flawed data that, unless corrected and updated, could have serious economic consequences for the business broadband market,” said CenturyLink Senior Vice President for Public Policy and Government Relations John F. Jones in a prepared statement on the company’s blog.

“We’re asking the FCC to rescind the affected portions of its proposal and update its data before pronouncing judgment on what is or isn’t competitive,” he added.

“The FCC’s FNPRM proposes a big, positive step towards deregulating competitive areas. However, the commission’s rulemaking decisions regarding pricing and additional regulation in non-competitive markets must be grounded on a sound factual basis. It has now become clear that the report prepared by Dr. Marc Rysman used in the FCC rulemaking, as well as nearly all other analyses submitted into the record, were based on an irretrievably flawed data set that severely understated cable providers’ ability to provision true business data services,” the companies’ motion said.

Major cable providers did not clearly or fully report that they were able to provide business data services using metro Ethernet in 22 times more census blocks than were reflected by the original data in 2013, according to the motion.

The FCC in April voted to ban contractual practices with historically entrenched companies like AT&T and Verizon.
