The American National Standards Institute has approved ANSI/SCTE 226 2015, "Cable Facility Classification Definitions and Requirements." The standard defines classes of critical facilities along with expected performance availability across five classes of structures, with the aim of creating a common nomenclature for critical facilities.
The standard is available at http://www.scte.org/SCTE/Standards/Download/SCTE/Standards/Download_SCTE_Standards.aspx.
