Pac-West provided no specific details in its motion as to how it would propose that an expedited dispute resolution process regarding the 3:1 ratio be implemented. Therefore, further study will be necessary before a final determination can be made concerning the details of any expedited process that may be appropriate to resolve disputes over the 3:1 ration presumption of traffic imbalance under the FCC Order. There is no basis, however, to delay carriers' implementation of the FCC Order merely because no specific dispute resolution process has been established to permit carriers to rebut the 3:1 presumption.
