About DCS Switch Settings
The Distributed Communications System (DCS) for a system is connected to the system through the
Processor Interface circuit pack. The first circuit can be connected directly to the DCS through the
processor interface (PI) connector on the rear of the control carrier.
Any of the remaining three circuits on the processor interface used to support the Distributed
Communications System (DCS) must be connected through a data module serving as the interface link.
The option settings for a 7400A Data Module are shown in
