Abstract
A telecommunications system is arranged to efficiently route digital information from a mobile network to a Public Switched Telephone Network (PSTN) and vice versa by interposing a packet network between the mobile network and PSTN so that digital information originating from the wireless network at a first data rate may be forwarded over the packet network at that rate and then sent over a direct connection from the packet network to the PSTN at a second data rate expected by the PSTN. In this way the conversion of the digital information from the first to the second data rate is performed only when needed, i.e., at the ATM switch connected to the PSTN.
