FT-2000 OC-48 Dual ADR Terminal
(D-Bay) 3
Equipment Packages 3
This equipment package is identified as J68974D. Conceptually, the D-Bay is very
similar to the E-Bay. The main differences are:
â– A modified power distribution and fuse panel
â– A more compact arrangement of the circuit pack shelves
■A new high-speed shelf—which is identified as the "Condensed
High-Speed Shelf"
■A new fan assembly—for forced air circulation
This configuration includes two Low-Speed/High-Speed shelf pairs and supports
two independent two-fiber ring systems. This means that the bay provides a total
of 96 slots. Thus, whenever the D-Bay is fully equipped, it is functionally
equivalent to two single OC-48 E-Bays. Figure 3-25 functionally depicts the
D-Bay.
NOTE:
In terms of operational features, there are no differences between the
E-Bay and the D-Bay. They both require the same circuit packs and same
generic software—FT-2000 ADR Release 7 or later.
