A system of distribution devices for handling data conductors or junctions between data conductors, the system comprising: a plurality of distribution devices (10, 11), wherein each distribution device (10, 11) comprises, a housing having assemblies for connecting and/or storing data conductors, and at least two physically and functionally separate functional regions (15, 16) in the housing, wherein a first functional region of each distribution device (10, 11) provides for at least one or more of connecting and storing data conductors, a second functional region of each distribution device (10, 11) provides exclusively for guiding data cables having the data conductors: characterised in that the plurality of the distribution devices (10, 11) are positioned next to each other or one above the other, in such a way that the second functional regions of one of the plurality of the distribution devices (10, 11) positioned next to each other or one above the other define a continuous cable guide channel which extends over the distribution devices (10, 11) positioned next to to each other or one above the other, in order to transfer data cables between the distribution devices (10, 11) in the horizontal or vertical direction and in a manner physically separated from the first functional regions of the plurality of distribution devices (10, 11); the first functional regions of the plurality of distribution devices positioned next to each other or one above the other are separated from one another by adjoining side walls (23, 24) of the housings, and further characterised in that the first functional region and the second functional region of the housing of each distribution device (10, 11) of the plurality of distribution devices are separated from one another by a side wall of a housing lower part of the respective housing, and wherein the side walls of the housing lower part of each distribution device of the plurality of distribution devices have at least one aperture for transferring the data cables having the data conductors between the two functional regions (15, 16). a plurality of distribution devices (10, 11), wherein each distribution device (10, 11) comprises, a housing having assemblies for connecting and/or storing data conductors, and at least two physically and functionally separate functional regions (15, 16) in the housing, wherein a housing having assemblies for connecting and/or storing data conductors, and at least two physically and functionally separate functional regions (15, 16) in the housing, wherein a first functional region of each distribution device (10, 11) provides for at least one or more of connecting and storing data conductors, a second functional region of each distribution device (10, 11) provides exclusively for guiding data cables having the data conductors: the plurality of the distribution devices (10, 11) are positioned next to each other or one above the other, in such a way that the second functional regions of one of the plurality of the distribution devices (10, 11) positioned next to each other or one above the other define a continuous cable guide channel which extends over the distribution devices (10, 11) positioned next to to each other or one above the other, in order to transfer data cables between the distribution devices (10, 11) in the horizontal or vertical direction and in a manner physically separated from the first functional regions of the plurality of distribution devices (10, 11); the first functional regions of the plurality of distribution devices positioned next to each other or one above the other are separated from one another by adjoining side walls (23, 24) of the housings, and further characterised in that the second functional regions of one of the plurality of the distribution devices (10, 11) positioned next to each other or one above the other define a continuous cable guide channel which extends over the distribution devices (10, 11) positioned next to to each other or one above the other, in order to transfer data cables between the distribution devices (10, 11) in the horizontal or vertical direction and in a manner physically separated from the first functional regions of the plurality of distribution devices (10, 11); the first functional regions of the plurality of distribution devices positioned next to each other or one above the other are separated from one another by adjoining side walls (23, 24) of the housings, and further characterised in that the first functional region and the second functional region of the housing of each distribution device (10, 11) of the plurality of distribution devices are separated from one another by a side wall of a housing lower part of the respective housing, and wherein the side walls of the housing lower part of each distribution device of the plurality of distribution devices have at least one aperture for transferring the data cables having the data conductors between the two functional regions (15, 16).
