DCS Connections

DCS Connections
Typically, cabinets are connected by distributed communication-system (DCS)
links using direct connections or modems.
The system uses the processor interface as the control circuit pack. The control
circuit pack provides a single EIA port that allows access to one data link.
Connections to the system vary depending on the distance between systems
and the type of system being connected.
