The Model 9483 NENA-compliant GPS master clock continues Spectracom’s tradition of delivering precise time synchronization for public safety answering points (PSAPs) and emergency command systems. Trusted by over 4,500 PSAPs across North America, it ensures accurate 911 event logging, faster response times, and seamless inter-agency coordination with Legally Traceable Time®.
This versatile NetClock supports expansion modules for enhanced capability and redundancy while maintaining strict compliance with the National Emergency Number Association (NENA) Master Clock Standard #04-002 and Next-Generation 911 initiatives, including the i3 Solution and Security TID #075-001 standards. It offers backward compatibility with legacy systems and supports a wide range of equipment including IP-based NTP/SNTP devices, IRIG, and RS-232 ASCII time code systems.
Compatible with essential PSAP equipment such as voice recorders, radio consoles, CAD, ANI/ALI, LAN networks, display clocks, fire alarms, and video surveillance, the 9483 delivers split-second timing critical for emergency communications centers to synchronize networks and log legally traceable events reliably.
Installation and management are simplified through front panel controls, SNMP support, enterprise directory authentication, Syslog error monitoring, DHCP, and IPv4/IPv6 dual-stack support. A browser-based user interface offers easy monitoring and configuration.
Enhanced security features surpass NENA standards, allowing selective enabling or disabling of features, interfaces, ports, and protocols. Remote login and secure file transfers ensure robust protection using industry-standard interfaces.
Designed for flexibility, the 9483 bridges legacy and network-based systems, providing a variety of timecodes, including all NENA formats, plus standard 10 MHz and 1 PPS signals. Optional T1/E1 outputs sync telecom systems. Additional network ports supporting Gigabit Ethernet enable synchronization across isolated networks or restricted administration.
For enhanced reliability, an integral oven-stabilized crystal oscillator (OCXO) provides at least 30 days of accurate holdover during GPS loss, while an optional Rubidium oscillator meets the demands of critical applications. Power options include integral AC, DC, or redundant AC/DC configurations, ensuring continuous operation in any environment.
