The Model 9483 NENA-compliant GPS master clock by Spectracom delivers essential time synchronization for public safety answering points (PSAPs), emergency, and command systems. Trusted by over 4,500 PSAPs in North America, it ensures accurate event validation, faster response, and seamless inter-agency coordination with legally traceable time.
Designed for versatility, the 9483 features expansion card modules for added capabilities, enhanced redundancy, and top-tier security on a network appliance. It supports legacy systems and complies with the National Emergency Number Association’s (NENA) Master Clock Standard #04-002, as well as Next-Generation 911 standards, including NENA’s i3 Solution and Security TID #075-001.
The NetClock integrates with virtually all PSAP equipment vendors and platforms, supporting IP-based NTP/SNTP systems, IRIG, and RS-232 ASCII time code legacy devices such as voice recorders, radio consoles, CAD, ANI/ALI, LAN networks, display clocks, fire alarms, and video surveillance systems.
Reliable timing is critical in emergency communication centers to synchronize networks and log events with legally traceable time. The 9483 excels at delivering precise, split-second timing to mission-critical systems with high reliability.
Setup and administration are user-friendly, with front-panel controls for network configuration and extensive protocol support, including SNMP, enterprise directory authentication, logging via Syslog, DHCP for easy installation, and IPv4/IPv6 dual-stack compatibility. A modern browser-based interface simplifies monitoring and configuration.
Security features surpass NENA standards for next-generation 911 systems, allowing granular control over interfaces, ports, and protocols. Remote login and secure file transfer enhance protection with industry-standard methods.
As a flexible master clock, the 9483 bridges legacy and modern network systems, offering multiple timecode formats (including all NENA standards), precise 10 MHz and 1 PPS outputs, and optional T1/E1 telecom synchronization signals. The built-in network port can be expanded with three additional Gigabit Ethernet ports to support isolated networks or segregated management access.
For enhanced reliability, an integral oven-controlled crystal oscillator (OCXO) ensures accurate synchronization for up to 30 days without GPS, while an optional Rubidium oscillator serves the most demanding applications. Power options include integral AC, DC, or both for redundancy, ensuring uninterrupted operation in critical environments.
