  • 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.
  • 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.
  • an adaptor 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.

  • 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.

  • Figure 1 is an exploded perspective view of a preferred embodiment of a telephone recording adaptor
  • FIG 2 is a circuit diagram of the telephone recording adaptor shown in Figure 1.
  • 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.

  • Capacitors 44 are 0.1 uf, 50 vdc capacitors.
  • 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.
  • the adaptor 10 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.
  • 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.
  • adaptor 10 modifications can be made to the structure and circuitry of adaptor 10.
  • 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.

Abstract

L'invention décrit un adaptateur (10) s'utilisant avec un téléphone cellulaire dont le combiné est pourvu d'une prise téléphonique modulaire reliée non fixe à une fiche téléphonique modulaire située dans l'ensemble téléphonique. L'adaptateur (10) possède un boîtier et une fiche d'adaptateur modulaire (14) montée dans le boîtier et conçue pour recevoir la prise modulaire du combiné. Une pluralité d'orifices de sortie (40) sont reliés électriquement aux broches respectives de la fiche d'adaptateur modulaire (14). Une pluralité d'orifices d'entrée (36) sont reliés électriquement aux orifices de sortie respectifs (40). Une prise d'adaptateur modulaire (20) est reliée aux orifices d'entrée (36) et est conçue pour se brancher dans la fiche modulaire de l'ensemble téléphonique. Une pluralité de commutateurs unipolaires sont montés dans le boîtier. Il y a un commutateur pour chaque orifice et les commutateurs sont divisés en un premier et un deuxième ensemble. Chaque commutateur possède un premier et un second côté. Une pluralité de lignes de captage (42) relie chacun des orifices de sortie à l'un des côtés des commutateurs. Une fiche de captage (16) est pourvue de deux terminaux, dont l'un d'entre eux est relié au deuxième côté du premier ensemble de terminaux et dont l'autre est relié au deuxième côté du deuxième ensemble de commutateurs. La pluralité d'orifices de sortie (40) et d'entrée (36) ainsi que la fiche de captage (16) sont également montées dans le boîtier.
