<p>A fixed wireless terminal utilizes a method for accessing a wireless local loop (WLL) telephone network to provide both a diagnostic mode of operation and a digital data delivery mode of operation in a system which utilizes a protocol which provides support for only the digital data delivery mode of operation. The method includes setting up a call (706) to a WLL device which includes a mobile station and a communication interface. The mobile station receives call setup signals followed optionally by a predetermined guard time (708). The communication interface is responsive to a predetermined guard time for switching to a diagnostic mode (712), and in the absence of the predetermined guard time being transmitted, the communication interface maintains the digital data delivery mode.</p> |
