• On December 12, 2012, Core Communications, Inc. filed a second request with the Pennsylvania Public Utility Commission (PAPUC) to extend the briefing deadlines in the proceeding it initiated against Windstream Pennsylvania, Inc., f/k/a Alltel Pennsylvania. Core filed a petition with the PAPUC in March 2006 to arbitrate its dispute with Windstream regarding compensation owed to Core for wireless traffic that Windstream sent to Core through a Verizon tandem switch. The dispute also includes issues of indirect interconnection volume limitations, third-party tandem services, the jurisdiction of “Virtual NXX” traffic, and reciprocal compensation. On October 4, 2012, the PAPUC ordered the parties to file opening briefs and affidavits by November 5, 2012 and reply briefs by November 26, 2012, but on Core’s request, the PAPUC moved the deadlines to December 14, 2012 and January 18, 2013. In its second request for extension, Core stated that it has been in negotiations with Windstream to resolve the parties’ dispute, but needs more time to attempt to reach a settlement. Docket No. A-310922F7004.
