If granted, the carriers told the Commission in a filing last week, they still would have to comply with most of their E911 obligations, including selecting, ordering, installing and optimizing Phase 2 technical solutions within 6 months of a public safety request or Sept. 1, 2003, whichever came later. They told the FCC that “no commercially available” Phase 2- compliant E911 location system now available could be deployed economically and meet accuracy standards through a licensed rural area. “Moreover, there is no record of support for imposing the same quantitative accuracy standards derived for a dense urban area on a sparsely-populated Tier 3 rural area where a 911 caller can be physically located more quickly notwithstanding a more flexible accuracy requirement,” the carriers said. They said that during the proposed forbearance period, stakeholders would work to overcome the many issues that continue to beset E911 Phase 2 solutions in the smallest rural markets served by the smallest group of wireless carriers -- Tier 3. “As these matters are resolved, E911 accuracy and reliability in Tier 3 markets can be expected to improve,” the filing said.
