ABSTRACT:
A novel and improved method and apparatus for providing an interface to a digital wireless telephone system compatible with standard analog wire line telephones, analog wire line fax machines, and computer modems is described. At the start of a telephone call, a data pump interprets the digits dialed, and if a first set of digits are received a control system configures the data pump for processing analog fax data. If a second set of digits are received, the control system configures the data pump for processing analog computer modem data. If a telephone number is received, the control system configures the interface system to pass additional data to a vocoder which encodes any digitized audio information received.
