ABSTRACT: Issue 1 of GR-3111, Generic Requirements for Transmission Characteristics for Network Equipment, describes the transmission criteria for high speed services over network connectors and passive components intended for use in the copper outside plant environment. This document augments the existing requirements contained in product specific GR documents.

This GR provides specific test methods for determining the transmission characteristics of network equipment and components used in the high-speed digital networks. In addition, criteria is provided for different products used in these digital network systems.

The criteria would help manufacturers supply network equipment with transmission characteristics that are better compatible with high-speed digital networks. In addition, these criteria would help network designers to optimize the transmission characteristics of the network and provide a better and more reliable service.

When using GR-3111, you may want to refer to GR-421, as well as various industry standards documents.
