pooling trials in different MSAs should be appropriately staggered to permit the industry to
undertake all necessary steps. The purpose of a staggered roll-out is to provide carriers time to
upgrade or replace their Service Control Points (SCPs) and other components of their network,
as necessary, if the increased volume of ported numbers as a result of the pooling trial requires
them to do so.
38. We suggest to the Ohio Commission that it consider concentrating its thousandsblock
pooling trial in those NPAs which are the best candidates for pooling, based on the
considerations set forth in the Numbering Resource Optimization Notice.7 For example, we
encourage the Ohio Commission to consider number pooling in areas where multiple LNPcapable
carriers exist. We also suggest to the Ohio Commission that it allow for exceptions to
participating in a pooling trial, if doing so would prove prohibitively expensive to a particular
carrier. For example, certain switch types may not be able to accommodate thousands-block
number pooling.88 Finally, as the Commission stated in the Numbering Resource Optimization
Notice, we encourage the Ohio Commission, to the extent it has not already done so, to consider
consolidating rate centers prior to implementing pooling.89 Fewer, larger pools logically increase
the effectiveness of thousands-block pooling.90
39. We reiterate that the authority we grant herein to the Ohio Commission to
undertake a thousands-block pooling trial is interim in nature, and is in no way intended to
relieve the Ohio Commission of its obligation to implement necessary area code relief in a timely
fashion. Whatever decisions the Commission reaches with regard to thousands-block pooling
administration and guidelines will supersede whatever systems the Ohio Commission puts in
place prior to enactment of those rules.
40. Technology- and/or service-specific overlays. The Ohio Commission also seeks
the authority to implement service-specific and technology-specific NPA overlays where such
overlays are found to be in the public interest.9' In the Numbering Resource Optimization
Notice, the Commission announced its intent to reexamine its prohibition on technology and
service-specific overlays and determined that it would address pending petitions for rulemaking
and waiver of this prohibition in the broader context of that proceeding.92 For this reason, we
decline to reach this portion of the Ohio Commission's request at this time.

that Winstar requires approximately 90 days to prepare its OSS systems for new pooling markets).
