scope:

This standard defines a minimal set of electrical requirements for a network end POTS splitter, often referred to as a central office (CO) POTS Splitter. The parameters defined include terminations, frequencies, testing, test signatures, dc characteristics, voice-band characteristics, attenuation, envelope delay distortion, impedance, longitudinal balance, and metallic balance. Additional features and performance characteristics may be included in a network end POTS splitter; however such features and performance characteristics are beyond the scope of this document.

Purpose

This standard is intended to facilitate the provisioning of various digital subscriber line (DSL) technologies and voice-band services over the same loop. The document is written broadly to permit the splitter to be used for current DSL technologies and potential new DSL technologies that use the same frequency spectra.
