Surge Waveforms for Various Standards
Surge Waveforms for Various Standards
TIA-968 now replaces FCC Part 68, except for hearing aid compatibility (HAC), volume
control, and indoor cabling. This has become harmonized with Canadian requirements.
Various countries around the world have adopted this regulation.
GR 1089 is a standard generally supported by the US Regional Bell Operating Companies
(RBOC). It is updated by Telcordia Technology (formerly Bellcore). The RBOC typically
requires compliance with GR 1089 for any of their telecom purchases.
ITU is a specialized agency of the UN devoted to international harmonization. Most
European countries recognize the ITU standards.
CNET is the Centre National d’etudes de Telecommunications, a French organization.
VDE is the Verband Deutsher Elektrotechniker, a Federation of German electrical
engineers. VDE is very similar to the IEEE (Institute of Electrical and Electronics Engineers)
but is national in scope rather than global.
ANSI is the American National Standards Institute, which is a non-government organization.
The British equivalent to this is BSI.
IEC is the International Electrotechnical Commission, a result of Europe’s move toward a
single market structure and its drive to formalize and harmonize member countries’
requirements.
FTZ R12 is a German specification.
Table 4.19 and Table 4.20 show the recommended SIDACtor device surge rating for each
standard.
