Support Maintenance Equipment --> Center:
center equipment commands

Definitions

center equipment commands (Information Flow): System-level control commands issued to center equipment such as reset and remote diagnostics.

Support Maintenance Equipment (Source Physical Object): 'Support Maintenance Equipment' represents the equipment used by IT personnel and technicians to locally or remotely troubleshoot, initialize, reprogram, and test IT assets that support ITS operations. It also manages service activities for IT assets, accepting service requests and providing service status as maintenance activities and repairs are scheduled and performed. It may include a workstation, laptop, trouble-ticket or other maintenance tracking software, specialized diagnostics tools, or any other general purpose or specialized equipment that is interfaced remotely or locally to support maintenance, repair, and upgrade.

Center (Destination Physical Object): This general physical object is used to model core capabilities that are common to any center.

Interoperability Description
Regional Interoperability throughout the geopolitical region is highly desirable, but if implemented differently in different transportation management jurisdictions, significant benefits will still accrue in each jurisdiction. Regardless, this Information Flow Triple should be implemented consistently within a transportation jurisdiction (i.e., the scope of a regional architecture).

Security

Information Flow Security
  Confidentiality Integrity Availability
Rating Moderate High High
Basis Commands could be sensitive and should include authentication data, thus should be MODERATE. Commands to Centers must be authenticated as having come from a source entitled to issue that command, or roadway equipment may be comprimised. Similarly, commands and configuration must be guaranteed to be correct; not manipulated midstream or corrupted, or the center may be mis-configured or compromised. Considered HIGH as opposed to MODERATE because the operational scope of a Center is typically quite large compared to a Field device. Without the ability to locally diagnose, operate, update and configure Center Equipment, the equipment is effectively out of control and would have to be taken out of service.
