The recommended on-hook requirements are written with a model of five (5) Customer Premise Equipment (CPE) attached to the Customer Interface (CI) and the minimum performance requirements are based on a model of three (3) CPE. This document propo

Any measurement procedure and equipment that can result in an identical measurement is considered valid. While the procedures may call out specific test points within the

40、 requirements, the full range of the requirements take precedent over the test method.
