Description
W09~/0S649 PCT/CA90/0030 CELLULAR TELEPHON~ R~CORDING ADAPTOR
TECHNICAL ~IELD
This invention relates to adaptors for use with telephone sets and more specifi~ally 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 pas~, 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 wirPd such that it can only be used with those telephones having predetermi~ed functions ~or each electrical wire or connection. A par~icular disadvantage of this prior art device is that it cannot~be used wlth a plurality of di~ferent telephones having different electrical wiring configura~ions. Further, it only records the incomtng portion o~ ~he telephone call.
It is desirable, particularly with cellular telephones used in cars, to provide a means for taping a ~elephone convexsation, so that the cellular telephone operator need not take notes while using the telephone. Further, ~here are presently a number of cellular telephones available which have dlfferent W092/05649 PCT/CA'jO/00305 electrical configurations and thererore lt is desirable to provide a device which is operable with a plurality of different cellular telephones.
The present invention seeks ~o provide a telephone recording device which can be used with a plurality of different telephone sets re~ardless of the particular electrical configuration and which records both incoming and outgoing messages.

BRIEF DESC~IPTION OF DRAWINGS:
Preferred embodiments of the lnven-tion will now be described, by way of exzmple, w1th reference to the accompanylng drawings, iIl which:
Fisure 1 is an exploded perspective view of a preferred embodiment of a telephone recording adap~or:
and Figure 2 is a circuit diagram of the telephone recording adaptor shown in Figure 1.
MODES FOR CARRYING OUlT INVENTION
Referring firstly ~o Figure 1, a preferred embodimen~ of a telephone recording adap~or is generally indicated by reference rumeral 10. Adaptor 10 has a circuit board 12 on which is mounted a conventional eigh~ pira telephone modula~ outpu ~ j ack 1~, a two pin tape recorde~ outpu~ jac~. 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 a~d the components mounted thereon and have suitable access openings 28, 30, 32 for accessing respectively, outpu~ jacks 14, 16 and dip switch 18. A further access openiny 34 permits input line 22 to enter the housing formed by housing members 24, 26. ::
Referring next to Figure 2, the circuit dlagram for adaptor 10 is shown. A plurallty 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 ~0 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 s1ngle pole swi~ches of dlp sw:tch 18 trrough .. . , .. . : , . ., ,. , .. , . . . . . .. - . ...... . ........... .

WO9./05619 ~ ~ ~ 9 ~ PCI/CA90/00305 respective capacitors 44. Capacitors 44 are 0.1 uf, 50 vdc capacitors.
It will be noted in Figure 2 that the output por~s 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 capacltors 44 for tap lines 1 and 8 can be eliminated, since these are ground lines, as discussed furthe~ below.
Tap lines ~2 are connec ed 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 ter~inal, 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 i5 placed in series between ~he handset and the mai~ 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 oL the cellular telephone.
In order to record telephone signals using adaptor 10, a plug ~rom 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 swi~ches 2 through 7.
It has been discovered that cellular telephones having handset plug corresponding to plug 20 universally have W092/~5649 ~ ~ ~ 9 ~ PCT/CA90/00305 1~
_ 5 _ pins 1 or 8 as a ground. It has further been discovered that at least one o~ pins 2 through 7 carry both the incoming and outgoing telephone or audi.o sl~nals ~hich switches of dip switch 18 should be closeà will depend upo~ the pa~tieular 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 swi~ches 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 o~ sent on the cellular telephone with which adaptc- 1~ is used.
Having described preferred embodiments, it lS will be appreciated that modifications can be made to the structure and circuitry OL adaptor 10. For example, different types o~ plugs and jac}cs 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 instructior.s would have to be included with adaptor 10 to indicate how the switches of dip switch 18 should be se~ fo- pa~ticular makes of cellular telephones.
