Method and system for initiating a data transfer in a cellular communications system
 In a wireless telecommunications system (40), a subscriber unit (44) transmits a request for a data connection (10) to cellular infrastructure equipment (46), wherein the data connection is between the requesting subscriber unit (42) and a data receiver (80,82) coupled to the cellular infrastructure equipment (46) via a public switched telephone network (68). In response to the transmitted request (10), data connection configuration parameters (78) stored in the cellular infrastructure (46) are selected (90), and the data connection is configured (208) according to the selected data configuration parameters. Data connection configuration parameters may include AT commands from the AT command set.
