<p>A wireless telephone subsystem for coupling line type telephony equipment to the public switched telephone network is described. A base unit (100) is provided which is adapted to be coupled to a plurality of lines of the PSTN. Base unit (100) is typically placed in a residence and acts as an interface between incoming phone lines and user handsets (301) and/or wireless subscriber loop interfaces (WSLI) (203) for connecting to fax machines, modems, conventional telephones, etc. Base unit (100) includes base coder/decoders (A3) for performing A/D and D/A transformations of analog PSTN signals and further includes a multiple channel transceiver (A15). A programmable switching means (A13) allows any handset (301) or WSLI (203) to access any of the plurality of lines or any other handset (301) or WSLI (203).</p> |
