David, I wonder if the Verizon document still refers to Issue 3 of GR-1089, which has been replaced by Issue 4 almost three years ago.
Issue 4 does no longer provide the possibility of an exemption, but asks for another test. See O4-15 in GR-1089 Issue 4. The objective has become a requirement in January 2008.

This is supported by Verizon document http://www.verizonnebs.com/TPRs/VZ-TPR-9305.pdf clause 7.2.12.1. Does this reflect current practice?
