These Notes outline technical requirements and fundamental principles of operator and
direct (customer) distance dialing. They are a revised edition of "Notes on Distance Dialing 1961,"
which superseded the earlier "Notes on Distance Dialing - 1956."

This issue of the Notes includes two sections not in previous issues. Section 8 discusses
International Dialing and Section 9 covers in general some of the new services that are now being
routed on the message network. The remaining sections have been generally updated and
revised.
