Electrical Operation
DCS wires attach to the lower four wire-wrap termination points on the
rear of the DNI-1B panel (NE-1); the network element wires attach to the
upper four points (NE-2). OUT (transmit) circuits attach to the upper pair
of termination points; IN (receive) circuits attach to the lower pair.
Inside the DNI-1B, the DCS IN circuits are hard-wired to the NE OUT cir-
cuits and the NE IN circuits to the DCS OUT circuits (internal cross-con-
nect, Tip-to-Tip and Ring-to-Ring):
