<p>A telepoint communications system (200) employs a method (621-633) of selectively changing the service state of a communication path. The telepoint system (200) includes a base unit (201) and at least one handset (210). The base unit (201) is coupled to a public switched telephone network (PSTN, 206) via at least one wireline (202), and is able to communicate with the handsets (210-220) via at least one radio frequency (RF) channel. The method includes the step of, at the handset (210), receiving (605) a PSTN access number from the base unit (201). The handset (210) might then signal (617), to the base unit (201), a service request (416) to change the service state for the PSTN wireline associated with the PSTN access number. The base unit (201) might, after receiving the request signal, alter the service state (508) of the PSTN wireline.</p> |
