Introduced: January 2015
Full Title
Full titles differ between systems:
IPC:
Line transmission systems > Details > Monitoring; Testing > Testing group delay or phase shift, e.g. timing jitter
CPC:
Line transmission systems (combined with near-field transmission systems H04B5/00) > Details > Monitoring; Testing > Testing group delay or phase shift, e.g. timing jitter
IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
IPC defines codes here since 2015.
