Mark, Is this section applicable to your product? Section 9.10 only applies to equipment that was formerly installed in an IBN system (now in a CBN), and newer products rarely fall into this category. At my last job, I performed a lot of GR-1089 evaluations and >95% of the products were exempt from 9.10. The only products I saw that fell into this category was some old 80's era boxes that had new cards to allow updated functionality (almost impossible to get them EMI compliant due to the initial design for LOW bandwidth & isolated shield grounds, but we got it.)
