In ONS 15540 training module 2, titled "Backplane and Chassis Configuration" page 5 provides a detailed breakdown of the fixed and non-configurable MUX/DMUX linecard to Transponder linecard backplane cross connects (wrt 4 & 8 Channel OADM's).
The text of page 8 however, implies that these backplane cross connects are wired differently for 16 Channel OADM's. Other documents suggest ONS components are compatible across the family, therefore this suggests either a misunderstanding on my part, or an ambiguity in the training material.
Yu-Tien Chi is the instructor of the material, and Larry Engel presented it. Would anyone care to clarify whether the backplane connections are accurately depicted on page 5 or not?
