This document provides a minimal set of pass/fail performance parameters for non-loaded metallic loops that have been designed and maintained to primarily support basic voicegrade analog services such as Plain Old Telephone Services (POTS). The document specifies end-to-end performance tests as well as single-ended performance tests. The document defines the methods, procedures, and equipment to be used for each test, and establishes the pass/fail criteria for each parameter being tested.
