The NTAC module communicates with the AMC circuit board of the INU
via a fast optical link using the standard DDCS protocol. The optical fibers
are connected to channel 1 of the AMC circuit board.
The NTAC interface is DIN rail-mounted inside the control compartment
(Fig. 3-6: 1).
The indicated mounting position can vary depending on the number of
optional devices present in the control compartment.
