inputs are also forwarded to the optional redundant crosspoint cardset. The optional redundant cros-
spoint cardset feeds any input to any output depending on which active crosspoint card it is taking
over for.
Outputs are distributed from each crosspoint card to specific output cards such that crosspoint cards
in the left side of the frame (when facing the front of the router) feed output cards located in the left
side of the frame. Similarly, crosspoint cards in the right side of the frame feed output cards located
in the right side of the frame, as shown in Figure 1-3 on page 7.
For more information on crosspoint cards, the slots into which they are inserted, and the signals
switched, see Crosspoint Slots and Signals Switched
on page 13.
