Definitions

  • a distributing frame for a telecommunication exchange includes a plurality of first groups of terminals, a plurality of second groups of terminals and a jumpering section containing the jumper wires for interconnecting the terminals between the first and second groups.
  • First separating means are located within the jumpering section and include a plurality of first subsections arranged in a predetermined direction.
  • Second separating means are also located in the jumpering section and comprise two second subsections arranged along a predetermined direction substantially perpendicular to the direction of the first subsections.
  • the first separating means consist of a plurality of horizontal jumper supports which are arranged in horizontal planes defining lower and upper subsections
  • the second separating means consist of vertical bars'carrying these horizontal jumper supports arranged in a similar vertical plane which 'subdivides the jumpering section in identical front and rear subsections.
  • two of these distribution frames are arranged back to back, i.e. with their rear subsections adjacent each other, those jumper wires which are arranged in the rear subsections are not easily accessible.
  • An object of this invention is to provide a distributing frame wherein the larger part of the jumper wires are accessible after they have been arranged on the horizontal jumper supports.
  • the inventive distributing frame therefore provides a maximum front subsection so that most of the jumper wires are easily accessible.
  • This distributing frame is also particularly suitable for being used in a back-toback arrangement with a similar distributing frame.
  • third separating means are mounted in the other second subsection to provide therein one or more first jumper wire guide channels each associated with a distinct one of said first subsections and each adapted for guiding jumper wires from the first groups of terminals into the associated first subsection, said first guide channels being arranged in said second direction.
  • fourth separating means are mounted in the second subsection to subdivide it in second jumper wire guide channels associated with particular members of the first subsections to guide jumper wires from said first subsections to said second groups of terminals, said second guide channels being arranged in the second direction.
  • each jumper wire interconnecting terminals of a first group and a second group is arranged successively in a first guide channel, a first subsection and a second guide channel. In this way the chance of making errors is reduced since the jumper wires do not interfere with each other.
  • Another advantage of the inventive distributing frame comprises a first apertured means mounted in a free section provided between the first groups of terminals and the first separating means, the apertures of each of said first apertured means being associated with distinct ones of said second subsections.
  • a further advantage of the inventive distributing frame is that a second apertured means is mounted' in a free section provided between the second guide channels and each of the second groups, the apertures of each of said second apertured means being associated with distinct ones of said second guide channels.
  • This invention therefore comprises a distributing frame for a telecommunication exchange which includes a plurality of first groups of terminals. a plurality of second groups of terminals, and jumper wires used to interconnect tenninals of said first and second groups. At least one auxiliary first group of terminals is associated with the plurality of first groups of terminals, and at least one auxiliary second group of terminals is associated with the plurality of second groups of terminals, and jumper wires are connected between terminals of the first group and the associated auxiliary first group. and between terminals of the second group and the associated auxiliary second group. Further electric connections are also provided between said first and second auxiliary groups of terminals.
  • One embodiment of the inventive distributing frame for a telecommunication exchange includes a plurality of line side panels and a plurality of exchange side panels separated by a jumpering section, above the first and below the second panels, the jumpering section houses jumper wires for interconnecting terminals of the line side panels and exchange side panels.
  • the jumpering section is subdivided into a rear subsection and a front subsection, wherein the front subsection is much larger than the rear subsection, by a plurality of vertical uprights arranged in the same vertical plane and carrying a plurality of hoiizontal jumper supports which are arranged in lower and upper horizontal planes defining a lower and-an upper subsection which are arranged in vertical direction.
  • the rear subsection constitutes a single first guide channel, whilst the front subsection is subdivided in both a rear and a first guide channel which are arranged in the same horizontal direction as the front and rear subsections.
  • the jumper wires connected to terminals of an odd numbered pair of line side panels are led successively through an associated lower fanning strip directly in the lower subsection, in the rear guide channel, and finally through the middle aperture of an upper fanning strip to an exchange side panel.
  • the jumper wires connected to terminals of an even numbered pair of line side panels are led successively through an associated lower fanning strip, in the first guide channel, in the upper subsection, in the front guide channel and finally through the front aperture of an upper fanning strip to an exchange side'panel.
