    description
      "This module contains a collection of YANG definitions for
supporting the Broadband Forum requirements on management of
ITU-T Passive Optical Network (PON) interfaces as defined in
ITU-T G.984.x, G.987.x, ITU-T G.989.x and ITU-T G.9807.x. As
such, this module is specific to access network equipment (e.g.,
BBF-specified Access Nodes and FTTdp DPUs).

Specifically, this module defines YANG types used for Optical
Network Unit (ONU) authentication and the decision to apply
an OMCI function.
