Testbed configuration planning was completed on October 26, 1997. Testing took place between November 11 and 25, 1997. This section contains the suggestions of the NTC Phase 10 Participants and Bellcore based on the findings of the NTC Phase 10 analysis. The following suggestions are based solely on Phase 10 results and should not be construed to represent a thorough analysis of the underlying issues. The underlying issues require further study and industry discussion before solutions can be accepted by the industry.
Some suggestions are direct enough that they are suggested for immediate consideration.
Those that are more complicated and may have additional implications are recommended for industry study. In order to avoid routing such calls to a customer with an assigned number that is the same as the LRN, it is strongly recommended that assigned numbers not be used for LRNs and that LRNs never be assigned to customers. As the impacts of such a solution are not known, however, it is suggested that this solution be referred to the NIIF for further study and industry discussion. Under normal conditions the probability of receiving such mis-coded IAMs is very low. However a faulty originating office could increase the probability by a few orders of magnitude.
