Abstract: A divan includes a seating surface and a backrest. In a first configuration, the backrest is positioned adjacent to the seating surface to support a person's back while the person is seated on the seating surface. In the first configuration, the seating surface is disposed at a first predetermined height above a horizontal plane. In a second configuration, the backrest establishes an upper bunk above the seating surface. In the second configuration, the seating surface establishes a lower bunk beneath the upper bunk. In the second configuration, the seating surface is disposed at a second predetermined height that is lower than the first predetermined height.

Abstract: A switch fabric architecture for a telecommunications system is described. In a basic aspect of the invention a N×N switch fabric and associated line cards are combined into a single shelf. In a 2N×2N switch fabric architecture, two shelves, each having a 2N×2N switch fabric with associated line cards, and 2:1 and 1:2 selectors are interconnected with inter-shelf cabling and in a 4N×4N switch fabric architecture, four such shelves are interconnected with appropriate inter-shelf cabling.
