APS 1+1 Redundancy Installation

APS 1+1 redundancy provides both card and line redundancy. It uses the standard BXM OC-3 and
OC-12 front cards but requires a special APS Redundant Backplane and APS Redundant backcards.
With previous card cages, because of the positioning of mechanical dividers, the APS card pairs could
be inserted only in slots 2 through 5 and 10 through 13. The mechanical dividers are located at slots 1
and 2, 5 and 6, 9 and 10, and 13 and 14.
With current card cages, this limitation is removed so that the APS card pairs can be located anywhere
except BCC cards slots 7 and 8, and ASM card slot 15. An APS 1+1 redundant card pair must be in
adjacent slots (2,3 or 4,5 and so on).
