On October 11, 2006, DOJ closed its investigation into the AT&T/BellSouth merger withoutfurther action. On December 29, 2006, FCC approved it. The competitive framework formedduring the preceding SBC/AT&T and Verizon/MCI merger proceedings was strengthened withthese approvals. However, the scope of the merger remedies including those ensured in themerger commitments is not so broad. They mainly focus on existing communications networksbased on PSTN, including no small parts of the Internet. Problems raised by the NextGeneration Network (NGN) and Fixed Mobile Convergence (FMC) are yet to be solved.Government authorities should make the comprehensive framework based on the layers modelfor the future.

On October 27, 2005, DOJ approved the SBC/AT&T and Verizon/MCI mergers. On October31, 2005, FCC authorized them. In these consent degrees, DOJ conditioned the divestiture ofsome special access connections to some buildings in these RBOCs'in-religion territories. Inaddition, FCC accepted voluntary, enforceable commitments made by the applicants as mergerconditions. These decisions altered the competitive framework of the U.S. telecommunicationsindustry since 1984, when former AT&T Corporation was divested. The TelecommunicationsAct of 1996 succeeded to the framework, and hypothesized that the PSTN continues to be theunrivaled infrastructure for the industry. Nevertheless, the rise of the IP-based networks hasoutdated it. FCC tried to modify the framework to accommodate to the Internet age.However, these adjustments also caused asymmetric regulations, which have caused a greatnumber of lawsuits since the AT&T Corp. v. City of Portland, 43 F. Supp. 2d 1146.Comprehensive legislation by the Congress based on the layers model is indispensable for thefuture.
