Description
CELLULAR TELEPHONE RECORDING ADAPTOR
TECHNICAL FIELD
This invention relates to adaptors for use with telephone sets and more specifically to adaptors for cellular telephones to permit tapping into the telephone signals.
BACKGROUND ART
In order to enhance the useability of a telephone set, in the past, devices have been developed to attach to a preexisting telephone set. For example, attachments have been provided to permit the recordal of the telephone signals on magnetic tape recorders. These devices normally do not work with cellular telephones, however, and none of them can be used universally with all or even most of the cellular telephones on the market, since cellular telephones have different electrical wiring configurations.
One example of a telephone signal recording apparatus is shown in U.S. Patent no. 4,446,335 issued on May 1, 1984 to C. E. Lee et al., which shows an apparatus for recording the incoming portion of a telephone conversation. The device is hard wired such that it can only be used with those telephones having predetermined functions for each electrical wire or connection. A particular disadvantage of this prior art device is that it cannot be used with a plurality of different telephones having different electrical wiring configurations. Further, it only records the incoming portion of the telephone call.
It is desirable, particularly with cellular telephones used in cars, to provide a means for taping a telephone conversation, so that the cellular telephone operator need not take notes while using the telephone. Further, there are presently a number of cellular telephones available which have different
electrical configurations and therefore it is desirable to provide a device which is operable with a plurality of different cellular telephones.
The present invention seeks to provide a telephone recording device which can be used with a plurality of different telephone sets regardless of the particular electrical configuration and which records both incoming and outgoing messages.
DISCLOSURE OF INVENTION According to one aspect of the invention, an adaptor is disclosed for use with a cellular telephone set having a hand set with a telephone modular plug releasably connected to a telephone modular jack in the telephone set. The adaptor has a housing and an adaptor modular jack mounted in the housing which is adapted to receive the hand set modular plug. A plurality of output ports are electrically connected to the respective pins of the adaptor modular jack. A plurality of input ports are electrically connected to respective ones of the plurality of output ports. An adaptor modular plug is connected to the input ports and is adapted to be plugged into the telephone set modular jack. A plurality of single pole switches are mounted in the housing. There is one switch for each output port and the switches are divided into first and second sets. Each switch has a first and second side. A plurality of tap lines connect each output port to one side of the switches. A tape jack with two terminals has one terminal connected to the second side of the first set of terminals and the ohter terminal is connected to the second side of the second set of switches. The plurality of output ports and input ports and the tape jack are also mounted in the housing.
BRIEF DESCRIPTION OF DRAWINGS:
Preferred embodiments of the invention will now be described, by way of example, with reference to the accompanying drawings, in which: Figure 1 is an exploded perspective view of a preferred embodiment of a telephone recording adaptor; and
Figure 2 is a circuit diagram of the telephone recording adaptor shown in Figure 1.
MODES FOR CARRYING OUT INVENTION
Referring firstly to Figure 1, a preferred embodiment of a telephone recording adaptor is generally indicated by reference numeral 10. Adaptor 10 has a circuit board 12 on which is mounted a conventional eight pin telephone modular output jack 14, a two pin tape recorder output jack 16, and an eight pin dip switch 18. A conventional eight pin telephone modular input plug 20 is electrically connected to circuit board 12 through an eight wire input line 22.
Upper and lower housing members 24, 26 enclose circuit board 12 and the components mounted thereon and have suitable access openings 28, 30, 32 for accessing respectively, output jacks 14, 16 and dip switch 18. A further access opening 34 permits input line 22 to enter the housing formed by housing members 24, 26.
Referring next to Figure 2, the circuit diagram for adaptor 10 is shown. A plurality of input ports 36 are provided to attach respective wires of input line 22 to printed circuit interconnection lines 38. Similarly, a plurality of output ports 40 connect modular output jack 14 to printed circuit interconnection lines 38. A plurality of tap lines 42 connect each interconnection line 38 to one of the single pole switches of dip switch 18 through
respective capacitors 44. Capacitors 44 are 0.1 uf, 50 vdc capacitors.
It will be noted in Figure 2 that the output ports 40 are numbered from 1 to 8, as are tap lines 42, the switches of dip switch 18 and the corresponding pins of jack 14 and plug 20. Pins 1 and 8 are first and last pins or ports and pins 2 through 7 are intermediate pins or ports. The switches of dip switch 18 are thus connected in parallel with input and output ports 36, 40. If desired, the capacitors 44 for tap lines 1 and 8 can be eliminated, since these are ground lines, as discussed further below.
Tap lines 42 are connected to the first or input side of dip switch 18. Pins 1 and 8 of the second or output side of dip switch 18 are wired together and are connected to one terminal, preferably the ground terminal of output jack 16. The remaining pins 2 through 7 of the output side of dip switch 18 are also wired together and are connected to the other terminal of output jack 16. Dip switches 1 and 8 form one set of switches and dip switches 2 through 7 form a second set of switches.
In use, the adaptor 10 is placed in series between the handset and the main power supply portion of a cellular telephone set. Modular plug 20 is the same type that is universally found on cellular telephone handsets, and modular jack 14 is the type that receives modular plug 20. Connected in this way with all of the switches of dip switch 18 open, adaptor 10 just acts as a patch cord and has no effect on the operation of the cellular telephone.
In order to record telephone signals using adaptor 10, a plug from a tape recorder is inserted into jack 16 and one of the dip switches 1 and 8 is closed along with one of the dip switches 2 through 7. It has been discovered that cellular telephones having handset plug corresponding to plug 20 universally have
pins 1 or 8 as a ground. It has further been discovered that at least one of pins 2 through 7 carry both the incoming and outgoing telephone or audio signals. Which switches of dip switch 18 should be closed will depend upon the particular make of cellular telephone and is a simple matter of trial and error to determine for any make of telephone. Capacitors 44 prevent any damage from being done by closing the incorrect switches of dip switch 18. With adaptor 10 configured in this way, a voice activated tape recorder connected to jack 16 will record all incoming and outgoing messages received or sent on the cellular telephone with which adaptor 10 is used.
Having described preferred embodiments, it will be appreciated that modifications can be made to the structure and circuitry of adaptor 10. For example, different types of plugs and jacks could be used, and of course, the number of wires or pins could vary. Printed circuit board 12 could be replaced with hard wiring, and input line 22 could be connected directly to output ports 40 as could tap lines 42. In this case, input ports 36 would be the same or co- terminus with output ports 40. Capacitors 44 could be eliminated, but instructions would have to be included with adaptor 10 to indicate how the switches of dip switch 18 should be set for particular makes of cellular telephones.
