scope:

The present document is intended to provide an introduction to the Converged Cable Access Platform (CCAP) architecture. The CCAP architecture has been specified in an integrated and a modular implementation. The present document describes both the integrated and modular architectures and discusses the various specifications that contain normative requirements pertaining to the CCAP. In addition, the present document describes the architectural entities and interfaces that make up the integrated and modular implementations, as well as the protocols they support. For the modular implementation, the present document provides an overview of the operation of Packet Shelf and Access Shelf devices, as well as the interface between them.
