Abstract

A system for providing fixed wireless access to standard telephony device is disclosed. A subscriber unit comprising a telephony interface for connecting to a standard telephony device, and a transceiver for establishing a communication link with a wireless network is used for providing telephony service to standard telephony device. Dual tone multiple frequency (DTMF) tones produced by said standard telephony device are sent to the wireless network, either directly or indirectly in the form of digit messages corresponding to the dialed digits, after a call set up message is sent. The subscriber unit sends a special set up message which identifies the subscriber unit as a terminal which sends digits on a digit by digit basis. A wireless network component (e.g. an MSC) is configured to identify such a set up message and upon receiving such a set up message collects and analyses digits sent by a subscriber unit on a digit by digit basis in order to provide a service feature or to connect a call._
