Digital Trunk

Two DSU cabinets may be programmed in a single DSU

node. On the left side of the node, slots 1, 2, and 3 comprise

one DSU cabinet. On the right side of the node, slots 4, 5,

and 6 comprise another DSU cabinet. When you program

cards in the left cabinet, program slot 3 before slot 2. When

you program cards in the right cabinet, program slot 5 before

slot 4. If you do not follow this order of programming, the

DSU cards on the side of the node that you are programming

will reset when you add the second card and the cabinet will

go out of service for one or two minutes.
