The member has a receptacle disposed at least partially along a length of the member. In one embodiment, the receptacle is a U-shaped channel which extends along the length of the elongated member. A retainer includes a flange that can be inserted in the receptacle and is sidable along the length of the receptacle. A second channel is provided for detachably securing the elongated member to a cable trough. A third channel may be provided on a front face of the elongated member for retaining a designation chart. The chart may be marked to indicate cable designations.

Abstract: A digital cross-connect module with a housing formed of two portions which slidably engage one another. One of the portions includes tabs which engage slots formed in the other portion. The two portions are formed of plastic, so the module housing is lighter and easier to produce than conventional housings. The housing contains a printed circuit board (PCB). The PCB has a first plurality of jacks adjacent the front of the housing and a second plurality of jacks adjacent the rear of the housing for cross-connecting digital signals.
