Abstract
A method and protocol for creating R2 data connections over a telecommunications connection is presented. The protocol includes a small set of signals used to create a data connection over a telecommunications using R2-MFC signaling for voice connections. The method includes a first set of methods for R2-MFC short cycling and a second set of methods for R2-MFC spoofing. R2-MFC short cycling uses the R2 data connection protocol and a tone detection apparatus to create a data connection. R2-MFC spoofing uses the R2 data connection protocol to create a data connection without a tone detection apparatus to detect a forward register signal. The method and protocol allow a data connection to be quickly and economically completed using R2-MFC signaling. The method and protocol are suitable for data services such as Internet or intranet access and teleconferencing.
