Abstract: In order to protect electrical and fiber optic cables in a central telephone office terminal equipment frame, the cables are controlled and managed so as to be releasably retained in a service loop within a fiber management panel. The releasable retention is performed by a stretched extension spring selected, dimensioned and stretched in such a manner with respect to the diameter of the cables that each cable can be gently but firmly retained when pressed into the gap between adjacent coils. The retention spring permits emergency release of the cable in the event of mishandling of the equipment by service personnel.

Abstract: The invention electronically identifies whether a computer module board is placed in the correct mechanical slot in a computer frame. A conductive line is connected to at least one electronic connector location in each mechanical slot in a computer frame. A computer module has open circuit electrical connectors which if put in the correct slot will mate with the locations in the slot in the frame which are connected to the conductive line. The other electrical connections which are used for identification are connected to a ground plane in the computer module board. A voltage source is connected through a resistor to a conductive line in the computer frame producing a high signal. If any computer module board engaged in a slot of the computer frame is in the incorrect slot, a low signal will be caused indicating the fault. The fault signal will be supplied to a power supply controller which prevents operating power from being provided to the computer boards.
