  • the information accompanying the incoming calls is preferably out-of-band signaling generated by the wireless telecommunications network 12 that is transmitted to the wireless transceiver.
  • the information may include out-of-band signaling that identifies if an incoming call is destined for a facsimile machine rather than a telephone, or vice versa.
  • the information may also be transmitted by the telecommunications network via in-band signaling.
  • in-band signaling information may be used to switch lines during a call.
  • the first and second ports 20, 22 couple the switching apparatus with the telecommunications devices 14, 16.
  • the ports are preferably conventional female-type couplers such as RJ-11 jacks operable for coupling with corresponding male-type jacks connected to the telecommunications devices.
  • the switching circuitry 24 is operably coupled with the input 18, the first port 20, and the second port 22 and is operable for selectively connecting an incoming call to a particular telecommunications device 14 or 16 connected to the switching apparatus without ringing other telecommunications devices that are also connected to the same switching apparatus as a function of information accompanying the incoming call.
  • the preferred switching circuitry broadly includes a processor 26, a subscriber loop interface circuit 28, and a switching device 30.
  • the processor 26 is coupled with the wireless transceiver 18 and the subscriber loop interface circuit 28 via control lines and is configured for analyzing information accompanying the incoming call and for determining to which of the first and second telecommunications devices 14, 16 the incoming call should be connected as a function of the information as described below.
  • the processor may be a stand-alone device that is coupled with the wireless transceiver as illustrated in Fig. 1 or may be an integral component of the wireless transceiver.
  • the processor is a Model 80C186EC (Intel design) processor, manufactured as an integral component of the QUALCOMM MSM2300 wireless transceiver.
  • the subscriber loop interface circuit 28 is coupled with the wireless transceiver 18 for interfacing the transceiver with the first and second POTS telecommunications devices 14, 16.
  • the subscriber loop interface circuit permits the switching apparatus to operate as a wireless local loop so that the POTS devices are connected to tip and ring wires even though they transmit/receive calls from a wireless network rather than a landline network.
  • One subscriber loop interface circuit that may be used with the present invention is the model L8560A/C low-power subscriber loop interface circuit manufactured by Lucent Technologies.
  • the switching device 30 is coupled with the processor via control lines and is coupled between the subscriber loop interface circuit 28 and the first and second ports 20, 22 via tip and ring wires.
  • the switching device is operable for selectively connecting incoming calls to one of the first and second ports under the control of the processor 26 as described in more detail below.
  • the switching device may include any conventional switching components such as relays or semi conductor switches and may include other electronic components such as transistor-type drivers.
  • the switching device may be a stand-alone device that is coupled with the subscriber loop interface circuit as illustrated in Fig. 1 or may be an integral component of the subscriber loop interface circuit.
  • the processor 26 is first programmed or configured to connect incoming calls to the ports 20, 22 in a prescribed manner as a function of the information accompanying the calls.
  • the processor may be configured to connect all incoming calls that are accompanied by information that indicates that the calls are destined for a facsimile machine to the first port 20 and to connect all incoming calls that are accompanied by information that indicates that the calls are destined for a telephone to the second port 22.
  • the processor may be configured in this manner during manufacture, during set-up by an end user, or by automatically detecting the type of telecommunications device attached to each port.
  • the telecommunications devices 14, 16 are then coupled with the switching apparatus 10 by plugging jacks connected with the devices into the ports 20, 22 in a conventional manner.
  • Each telecommunications device is connected to a port.
  • the port can be designated during the configuration of the processor. For example, if the processor has been programmed to connect all incoming calls that are destined for a facsimile machine to the first port, a facsimile machine must be plugged into the first port. Or, the port designation can be indicated by the end user. Or, the type of telecommunications device can be automatically detected.
  • incoming calls are received and analyzed by the wireless transceiver 18 and processor 26.
  • the wireless transceiver and antenna receive an incoming call and then trigger the processor before the transceiver causes the components coupled therewith to go off-hook.
  • the processor analyzes the information accompanying the incoming call to determine what type of call (e.g., voice, data, facsimile) is being received.
  • the processor 26 determines the type of incoming call, it signals the switching device 30 to connect to the appropriate port 20 or 22. For example, if the processor determines that an incoming call is destined for a facsimile machine, it signals the switching device to connect to the first port 20, which has been coupled with a facsimile machine 14 in the example described above.
  • the wireless transceiver 18 next connects the incoming call to the subscriber loop interface circuit 28, which in turn transfers the call to the appropriate telecommunications device through the port that has been selected by the switching device.
  • the call is then answered in a conventional manner, for example, when a user takes the phone off-hook or when the facsimile machine automatically answers the call.
  • the off-hook condition is detected by the subscriber loop interface circuit, which then signals the wireless transceiver to pass the incoming call to the selected telecommunications device.
  • the switching apparatus 10 of the present invention therefore connects an incoming call to a particular telecommunications device as a function of information accompanying the call without ringing other devices coupled with the switching apparatus. This provides an advantage over prior art devices in that calls are directed only to the appropriate telecommunications device so as to avoid unwanted ringing or connection attempts.
  • the switching apparatus of the present invention is preferably implemented in connection with a wireless telecommunications network as a part of a wireless local loop, it may also be implemented in connection with conventional landline communications networks.
