The CRTC partially denied an application Tuesday from Ontario-based Fibernetics Corp. to overturn an earlier decision related to tariffs. Fibernetics had asked the commission revoke a section of an earlier decision that had designated when and how new tariffs could be applied to local exchange carriers, or phone companies, that cause imbalances in traffic patterns generated by dial-up Internet and two-stage long distance calling services. At issue is CRTC telecom decision CRTC 2010-787, which said imbalance compensation payments to local exchange carriers is limited to cases in which the total traffic volume is less than 10 million minutes per month and where “the volume of traffic in one direction is more than 80 percent of the total traffic exchanged between LECs .” In that earlier decision, the CRTC had said that Bell Aliant and Bell Canada had suggested these limitations be measured over a three-month period when determining whether a carrier would receive an imbalance payment or discount. But following the decision, Fibernetics complained to the commission that neither Bell or any of its subsidiaries had proposed a three-month period of measurement and that the decision was arbitrary and inappropriate. The CRTC acknowledged Tuesday that it had inadvertently attributed the suggestion of the three-month period to Bell but ruled that the substance of its earlier decision is not affected. The commission ruled in favour of Fibernetics by noting that Bell inappropriately applied the three-month term to only local exchange carriers that filed initial applications for discounts related to traffic imbalances and not those that re-applied after previously losing access to discounts.
