DALLAS — Dallas' new $6.5 million dispatch system went offline for at least 30 minutes Thursday morning, forcing police to revert to an old-fashioned method of sending police and firefighters to emergency calls.
Officials said the problem arose because of an error by a technician who was working on the system.
"It was human error," said Worris Levine, head of the city's communications and information services department.
