Abstract
This invention relates to a call-source identification device comprising: a calling line identification receiver hard wire connectable to an incoming telephone line and adapted to sense a component of a telephone call signal that identifies the source of the call; a first transmitter and associated circuitry for radio channel transmitting the component; a first receiver for receiving the component;and signal processing means connected to said first receiver for processing the component to display the source information conveyed thereby.
Description
2i48g5~
BACKGROUND OF THE INVENTION
This invention relates to a call-source identification device for use with a telephone set.
Call-source identification devices have been in use for several years. Telephone call signals transmitted over most telephone lines include a digital component that identifies the source of the call. These devices take this component, convert it to analog form and display the call-source information so that the user can identify the caller before the phone is answered.
These devices are also programmable to exclude predetermined telephone sources from reaching a telephone set.
Useful as these devices have been and extensive as has been their use, their utility has by no means reached its attainable maximum capacity. The read-out of the information they yield is, of necessity, physically close to the telephone set because the device is hard-wired to the telephone. In the case where a telephone user finds it more convenient to use an extension telephone, he does not have access to the call-source information, nor does he have access if he is distant to the telephone.
SUMMARY OF THE lNV~N'l'ION
I have found that the utility of these devices can be increased manyfold by transmitting the component to a receiver for display at a remote location to the station where the call is detected. The remote location can have means to transmit instructions back to station where the call was received for processing; or, if the remote station is an extension to a telephone, a user can accept or reject the call by manipulation of the hand receiver of the extension telephone.
21~89~
-The remote call-source identification display device of this invention is not hard-wire connected to the telephone line. It is portable and can fit in a small pocket or purse. Moreover it is inexpensive. It is an improvement to the present devices in which the visual display elements are hard-wired to the telephone station and it is an improvement that increases utility in much greater proportion than it increases cost.
It is an object of this invention to provide a call-source identification device for a telephone station that will give a read-out at a location remote from the telephone station.
It is a further object of this invention to provide a call-source identification display device with which the user can terminate a telephone call from a remote location after having identified the call source.
It is a further object of this invention to provide a remote call-source identification device that can be programmed from its remote location to eliminate further calls from a particular calling source.
Other objects of the invention will be apparent after reading the specification.
With these and other objects in view a call-source identification device for a telephone station according to this invention has a calling line identification receiver adapted to sense a component of a telephone call signal that identifies the source of an incoming call; a first transmitter and associated circuitry for radio-channel transmitting the component to a remote location; a first receiver for receiving the component at the remote location; and signal processing means at the receiver for processing the component to display the source information conveyed thereby.
214~9~6 -BRIEF DESCRIPTION OF THE DRAWINGS
The invention will be readily understood after reading the following specification in conjunction with the drawings in which:
Figure 1 is a block diagram showing the main components of a remote call-source identification device according to this invention connected to a telephone set and telephone line.
DETAILED DESCRIPTION
Referring to the drawings figure 1 shows a block diagram of a call-source identification device according to this invention connected to a telephone station 10 which in this case is a conventional hand telephone but could alternatively be a telephone answering machine, a telefax machine, a computer or any other instrument adapted to receive an incoming telephone signal.
Incoming telephone call signals on line 12 to the telephone 10 have a component that identifies the calling station. In this invention, they pass through a call identification receiver 14 that is able to identify this component and pass it to a micro-controller 16. Micro-controller 16 is essentially a computer programmed to take the incoming digital source-identifying signal, convert it to analogue form and feed it to a liquid display device 18 that visually displays the identity of the call source on the basis of the component characteristic.
Programming of the micro-controller 16 is accomplished in assembly code using a code embedder.
214~95~
~ The liquid crystal display device 18 is physically close to the telephone so that a telephone attendant can look at the display device 18 and learn the source of the call. He has this information before he picks up the receiver. Thus, if he does not want to take the call he either does not pick up the receiver or he picks up the receiver and immediately lowers it to terminate the call.
The operation thus far described is well known and has been in substantial use for several years. The concept of screening calls is useful but its utility has been restricted because the display device is hard wired to, and is therefor physically close to, the telephone with the result that the user must be close to the telephone. The arrangement is of no use to a person who must move from the telephone because, after moving from the telphone, he cannot see the display device.
With this invention it is possible to screen calls at locations remote from the telephone, even in cases where the user is continually moving from place to place. With the invention, the analogue form of the signal that identifies the source is conducted from the micro processor 16 to an FKS-FM radio channel transmitter 20 for radio channel transmission to an FKS-FM
receiver 22, which is at a remote location to the transmitter.
The received signal is stripped of the FKS component in stripper 24 from which it passes to liquid display device 26 which displays the characteristics of the call signal for the incoming call.
To have this information available at a location remote from the telephone set materially increases the utility of the concept of providing a visual read-out of the origin of a call because it permits a person at a telephone extension, for example, to benefit from the knowledge and to attend to the telephone accordingly. The invention provides even greater utility for the 21489~
concept of information display because it further permits a person at a remote station to cut a call and/or add a call number to a stored list of numbers from which calls will always be rejected, whether or not he is at a telephone extension.
In this latter respect the apparatus at the remote station includes an FSK FM transmitter 30 which, when activated, transmits signals to a tuned receiver 32 at the location of the transmitter 20. Numeral 34 is a signal switch with three activating buttons. One button, when activated causes transmitter 30 to send a signal to receiver 32 which in turn conducts it to micro-controller 16 via FSK stripper 35 that commands the micro-controller to reject the incoming call.
Another button causes a different signal to travel the same route to command the micro controller to accept the incoming call. The third button causes a signal to travel the same route to command the micro-controller to reject the call and to store the call number in a list of numbers stored in the auxiliary RAM
memory 36 of the micro-processor 20 that are to be always rejected.
Micro controller 20 is a computer and is programmed to do various things in response to appropriate signals from the control panel 34. In any given requirement one or more of the three of the operations described above may not be required. It is also contemplated that the micro controller may be programmed to do other things.
The elements that are illustrated as hard wire connected to the remote receiver 22 are all available in compact form and can be housed in a portable casing represented in the drawing by box 38 of a size that will conveniently fit a shirt breast pocket.
They are conveniently powered by a small 1.5v AA battery (not shown in the schematic drawing) 2148~5h The elements shown as hard-wire connected to the micro-controller 16 are housed in a convenient casing such as that represented by box 40 with a socket as at 42 to receive a jack on line 12 and a socket as at 44 to receive the jack from telephone 10. Numeral 46 is a cord for connecting the device to a standard AC power supply to supply power to the operating parts by way of appropriate DC converters not illustrated in the drawings.
All essential constituent basic elements are available on the open market and following is a list of suppliers of elements that work well in the device.
