OUC Network

OUC’s award-winning network includes the technologies discussed below.

911 Computerized Telephony

Computerized telephony provides a redundant, secure and robust emergency telephone network. All wireless (cellular) carriers have been placed on the District’s own selective router. Once all carriers are connected directly, the District will be the first and only Public Safety Answering Point (PSAP) in the nation to accept and route calls within an independent, municipally owned infrastructure.

Computer Aided Dispatch (CAD) and Associated Geographic Information Systems (GIS)

These technologies use computerized mapping and analytical features to track and display AVL/GPS-equipped fire and police units. This helps dispatchers make recommendations by finding the closest and best-equipped units for any given emergency.

Emergency Dispatch Instruction Software

This software enables OUC staff to provide 911 callers with life-saving, pre-arrival instructions over the phone. These instructions can help District callers stabilize and, in some cases, save the lives of patients during the vital seconds between the 911 call and unit arrival.

TDD/TTY Computerized Systems

These systems instantly recognize TDD/TTY calls from citizens who are deaf or hard of hearing. The systems provide customized, pre-programmed phrases that enable call-takers to speak directly to the TDD/TTY devices.

Computerized Radio Dispatch Systems Consoles

These consoles connect OUC staff with both handheld and mobile radio systems used by police, fire and emergency medical services.

Redundant Trunked Radio Network

This network comprises nearly a dozen radio towers connected by a computerized master controller. The controller contains the master radio database and acts as the primary point for audio path control within the network. Each tower site can also function independently, providing first responders with the solid redundant communications they need.

Computerized Recording Systems

These systems provide both operational and legal protection. They allow OUC personnel to instantly replay the last 20 minutes of calls made to the center. They are also used for training, quality assurance and, in some cases, various legal proceedings.
