About Our Dispatch System

OUC uses Intergraph’s emergency response system environment for handling 911 calls. This system allows dispatchers to see emergency vehicles and the events they are responding to on a graphical map that updates automatically on computer screens. The system also involves video and voice communications systems on a broadband network.

In the late 1990s, DC’s 911 dispatch system was the worst in the country. Since then, we have built a fully redundant E911 network infrastructure and the modernization is 90 percent complete. The National Emergency Number Association has pronounced the District’s network to be a model of how E911 services should be engineered.

System Highlights

  • All wireless carriers are on the “selective router” system
  • Wireline carriers are in the process of being migrated onto the system
  • System will accommodate Voice Over-Internet Protocol (VoIP) carriers as well

Future Plans

  • Migrating carriers/calls onto the Unified Communications Center (UCC) telephone system
  • Adding increased redundancy via backup at the Public Safety Communications Center (PSCC)
  • Completing the Automatic Location Identification (ALI) service
  • Determining ALI and engineering standards
