Introduced: September 1968
Full Title
Full titles differ between systems:
IPC:
Line transmission systems > Systems for transmission power distribution lines > Circuits for coupling, blocking, or by-passing of signals
CPC:
Line transmission systems (combined with near-field transmission systems H04B5/00) > Systems for transmission via power distribution lines > Circuits for coupling, blocking, or by-passing of signals
No child classifications to compare. This is a leaf node in both IPC and CPC.
