Introduced: January 1990

Full Title

Full titles differ between systems:

IPC:

Data switching networks > Circuit switching systems, i.e. systems in which the path is physically permanent during the communication

CPC:

Data switching networks (interconnection of, or transfer of information or other signals between, memories, input/output devices or central processing units G06F13/00) > Circuit switching systems, i.e. systems in which the path is physically permanent during the communication

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1990.
