Abstract: As a telecommunications device goes off-hook a simultaneous connection is made to a local exchange and a data network removing the necessity to dial, or input numbers to access the data network. Upon connection to the local data network, a modem tone is returned to the telecom device. Connection to the local exchange causes a dial tone to be returned to the DSLAM in the local change. The device receives the modem tone, the dial tone is blocked by the DSLAM and a data communication session begins. If the device transmits DTMF signals within 20 seconds, the call reverts to a standard switched call, dropping the connection with the local data network. If no DTMF signals are sent within 20 seconds, the DSLAM releases the connection with the local Exchange and the data communications session continues.

Abstract: The present invention installs an IP intranet functionality in a Mobile Switching Center for supporting wireless data and multimedia services within an operator community of interest. An IP network is introduced between a multimedia device and the Internet. The intranet provides a subnetwork and service context for wireless telco operators. Upon initiation of a service session by a multimedia terminal, the Mobile Switching Center presents the subscriber with an operator “intranet homepage” that serves as the primary navigator and launch pad for traversing the operator intranet or for launching a session on the Internet. If the initiating device is a voice only terminal, the Mobile Switching Center enables connection to another voice only terminal as usual.
