If I understand correctly, you are asking about the history of this line and the connection?  If so, run-through operations between the Chiyoda Line and the Joban Line (local service) began on April 20, 1971.  Back then the operating companies were Eidan (now Tokyo Metro) and JNR (now JR East).

Thanks for information! And yes, you understood everything correctly.
