Recommendation ITU-T G.7710/Y.1701 addresses the equipment management functions (EMFs) inside a transport network element that are common to multiple technologies. For example, common applications are described for date and time, fault management, configuration management, account management, performance management and security management. These applications result in the specification of common EMF functions and their requirements. The 2012 revision of this Recommendation has incorporated the following below. -Recommendation ITU-T G.7710/Y.1701 Corrigendum 1 (11/2009): this mainly contains an updated equipment management function process block diagram. -Recommendation ITU-T G.7710/Y.1701 Amendment 1 (07/2010): updates the packet layer related specification of severely errored second (SES) to align it with the SES definition in Recommendation ITU-T Y.1563. -Recommendation ITU-T G.7710/Y.1701 Corrigendum 2 (04/2011): this adds the missing 6 LBC terms to the process description, and gives additional specifications on gauge measurement. The 2019 revision of this Recommendation has incorporated the following below. -Recommendation ITU-T G.7710/Y.1701 Amendment 1 (9/2016): -Create new clause 12 for control plane function management, including fault event reporting for controller-based restoration.
