This Recommendation provides a set of carrier grade open environment (CGOE) components, each of which can be related to a CGOE category identified in the CGOE model that is defined in [ITU-T Y.2901]. These CGOE components are intended for use by vendors to assist them in developing commercial off-the-shelf (COTS) components. It is recognized that CGOE components will continue to be identified on a going forward basis and annexes will be added to capture these additions. Additionally, to ensure that a consistent approach is used in the generation of future annexes, a framework for the specification of new CGOE components is provided.
