COMMENTS: As noted earlier, the rules premise the threshold and any later assessments for RCF interim number portability on actual cost determinations made in a Commission proceeding or the use of proxies. If at the time the threshold is breached and the local exchange carrier begins to impose cost assessments the commission has not entered any order setting TELRIC RCF number portability costs, this section allows the local exchange carrier or any charged carrier to request that the Commission determine actual costs in a proceeding. Until such TELRIC costs are determined, the assessments may still be based upon the proxies, but subject to the later true-up procedure described in Section 5. Again, if all carriers are satisfied with continued use of the proxies during the remainder of the interim period, the Commission need not undertake a proceeding to determine TELRIC costs.
