| He is a "test" upload of an SXS composite drawing (1924) showing all the relays and connections involved in a call from a Phone to a Rotary Line Switch to a Selector(s) to a Connector to the called Phone. Sorry about the quality. The original diagram is in a book from 1924. I will have to see if I can make them better... |
