Transbeam said that is concerned that Verizon's ongoing shutdown of copper circuits could cause issues. The CLEC claims that Verizon has not offered the CLEC "a replacement offering that is a reasonably priced wholesale alternative." Verizon said in an earlier filing responding to Transbeam that claims made by Transbeam and Windstream that the XO asset acquisition will affect its copper retirement processes are without merit. Later, Verizon assured XO's existing CLEC customers that it would continue to support Ethernet over Copper services after it takes control of the assets -- depending on several factors. Verizon said that "intends to grandfather and continue to provide those XO services that are not migrated to an equivalent Verizon service." As part of its review of the EoC agreements XO has with its wholesale customers, Verizon said it plans to migrate those customers to "reasonably equivalent" Verizon business services.
