There is a company in Libertyville, IL that contacted me at Ameritech a few years ago that has several isolation/protection devices available as external primary and secondary protection. Now if I can just remember the name of the company....

Without the transformer isolation, the product would still be "metallically connected" to the OSP and all tests for Type 1 or Type 3 interfaces (depending upon the intended deployment location) would need to be performed. If and when Dwight finds an external protection device, he will need to test his product with that specific external device for compliance, and then state in the installation practice that this specific external protector MUST be used.
