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.
