Next generation switching (NGS) system maintenance operations model

  • K. F. Li


This paper provides a view of the next generation switching (NGS) system maintenance operations model based on potential switching technologies. Several potential benefits of the NGS system maintenance over today's switch maintenance are discussed with emphasis on functions but not on costs. A set of maintenance functions required for the NGS system is provided, using the LSSGR and OTGR as guidelines. The definition associated with each maintenance function is also presented. Finally, issues related to the NGS module structure and definition are identified and discussed because the progress of the overall NGS work is largely dependent on the resolution of these issues. The purpose of this work is twofold: (i) to place switch maintenance functions into the NGS operations model; and (ii) to provide a guideline for further defining switch maintenance functions which are/will be unique to NGS.
