ABSTRACT:
A card rack is provided for removably housing two types of circuit packs in respective first and second portions, e.g., upper and lower portions of the card rack. The card rack includes connectors for interconnecting components on the circuit packs with one another and to input and output cables. The input cables are connected only to circuit packs of one type which are disposed only in one, e.g., the lower, portion of the card rack. The upper card rack portion overhangs the lower card rack portion for, in combination with sides of the card rack, forming a recessed space through which the input cables are routed to the lower portion circuit packs. The passage of the cables through the recessed space isolates the cables from becoming entangled with traffic passing in front of the card rack and thereby avoids the need for a separate door enclosing the front portion of the card rack. Preferably, the various circuit packs are relatively dimensioned for disposing innermost ends of the circuit packs in a common vertical plane for simplifying both the construction of the card rack and the arrangement used for interconnecting the various circuit packs.
