Minitel
The Minitel modem usually dialed a special number to connect to a PAVI (Point d'Accès VIdéotexte, "videotext access point"). The PAVI sent information to the correct servers on the Transpac X.25 network. In France the most common dial number was "36 15". "36 17" was for more expensive services. Minitel services names often started with this number. So, the "36 15" number at the front of the name was like the ".com" on Internet web sites.
